auto buildObjectFromJSONDoc(const std::string& templateName, const io::JsonGenericValue& jsonConfig) -> AttribsPtr override
Parse passed JSON Document for esp::metadata::attributes::AbstractAttributes. It always returns a valid esp::metadata::attributes::AbstractAttributes shared pointer.
void setValsFromJSONDoc(AttribsPtr attribs, const io::JsonGenericValue& jsonConfig) pure virtual
Method to take an existing attributes and set its values from passed json config file.
auto parseUserDefinedJsonVals(const attributes::AbstractAttributes::ptr& attribs, const io::JsonGenericValue& jsonConfig) const -> bool
This function takes the json block specifying user-defined values and parses it into the passed existing attributes.
auto parseSubconfigJsonVals(const std::string& subGroupName, const attributes::AbstractAttributes::ptr& attribs, const io::JsonGenericValue& jsonConfig) const -> bool
This function takes the passed json block jsonConfig, looks for subGroupName , and if found in json document and referencing an appropriately formatted object, will load the found values into a subconfig, keyed by subGroupName , placed into attribs ' subconfig tree.
auto getFullAttrNameFromStr(const std::string& attrName) const -> std::string
Returns actual attributes handle containing attrName as a substring, or the empty string if none exists. Does a substring search, and returns first value found.
void finalizeAttrPathsBeforeRegister(const AttribsPtr& attributes) const pure virtual

Protected functions

void filterAttribsFilenames(const AttribsPtr& attributes, const std::string& curRelPathName, const std::string& curFQPathName, const std::function<void(const std::string&)>& relPathSetter, const std::function<void(const std::string&)>& fqPathSetter) const
Called internally right before attribute registration. Filepaths in the json configs for Habitat SceneDatasets are specified relative to the location of the config in the file hierarchy. As the config is loaded, these filepaths will be fully qualified with absolute paths so that they can be easily found and consumed on command. However, saving fully qualified filepaths to JSON configs is undesirable.
auto createFromJsonOrDefaultInternal(const std::string& filename, std::string& msg, bool registerObj) -> AttribsPtr
Called intenrally from createObject. This will create either a file based AbstractAttributes or a default one based on whether the passed file name exists and has appropriate string tag/extension for esp::metadata::attributes::AbstractAttributes.
template<class M>
void setEnumStringFromJsonDoc(const io::JsonGenericValue& jsonConfig, const char* jsonTag, const std::string& mapName, bool saveUnspecified, const std::map<std::string, M>& mapToUse, const std::function<void(const std::string&)>& valueSetter)
This function is accessed by various attributes managers during loading. It provides a generic handler to look for a particular jsonTag in the given jsonConfig document, and if it is present it will attempt to find the value in the passed string-keyed mapToUse of enum config values. If the string is present it will return the string, otherwise it will return an empty string. The consumer of the function is responsible for only setting a config value if the string is not empty. The enum class should have the first value defined as Unspecified and given the value ID_UNDEFINED.
auto setFilenameFromDefaultTag(const AttribsPtr& attributes, const std::string& srcAssetFilename, const std::function<void(const std::string&)>& filenameSetter) -> bool
Set a filename attribute to hold the appropriate data if the existing attribute's given path contains the sentinel tag value defined at esp::metadata::CONFIG_NAME_AS_ASSET_FILENAME. This will be specified in the Scene Dataset configuration file in the "default_attributes" tag for any attributes which consume file names to specify that the name specified as the instanced attributes should also be used to build the name of the specified asset. The tag value will be replaced by the attributes object's simplified handle, or if unable to be found, with an empty string.
auto setAttributesHandleFromDefaultTag(const AttribsPtr& attributes, const std::string& srcAssetHandle, const std::function<void(const std::string&)>& handleSetter) -> bool
Set an attribute that holds another attribute's handle to hold the appropriate data if the existing attribute's given path contains the sentinel tag value defined at esp::metadata::CONFIG_NAME_AS_ASSET_FILENAME. This will be used in the Scene Dataset configuration file in the "default_attributes" tag for any attributes which consume attributes handle names to specify that the name given as the instanced attributes should also be used to build the name of the specified asset's handle. The tag value will be replaced by the attributes object's simplified handle.

template<class T, ManagedObjectAccess Access>
esp::metadata::managers::AttributesManager<T, Access>::AttributesManager(const std::string& attrType, const std::string& JSONTypeExt)

Construct an attributes manager to manage shared pointers of attributes of type T.

Parameters
attrType A string describing the type of attributes, for
JSONTypeExt The attributes JSON file extension, which must be of the form 'XXXXXX.json', where XXXXXX represents the sub extension specific to the managed type of attributes (i.e. "stage_config.json" for configurations describing stages).

template<class T, ManagedObjectAccess Access>
std::vector<int> esp::metadata::managers::AttributesManager<T, Access>::loadAllFileBasedTemplates(const std::vector<std::string>& tmpltFilenames, bool saveAsDefaults)

Load all file-based templates given string list of template file locations.

Parameters
tmpltFilenames list of file names of templates
saveAsDefaults Set these templates as un-deletable from library.
Returns vector holding IDs of templates that have been added

This will take the list of file names specified and load the referenced templates. It is assumed these files are JSON files currently.

template<class T, ManagedObjectAccess Access>
std::vector<int> esp::metadata::managers::AttributesManager<T, Access>::loadAllJSONConfigsFromPath(const std::string& path, bool saveAsDefaults = false)

Parameters
path A global path to configuration files or a directory containing such files.
saveAsDefaults Set the templates loaded as undeleteable default templates.
Returns A list of template indices for loaded valid configs

This will take the passed path string and either treat it as a file name or a directory, depending on what is found in the filesystem. If path does not end with JSONTypeExt_, it will append this and check to see if such a file exists, and load it. It will also check if path exists as a directory, and if so will perform a shallow search to find any files ending in JSONTypeExt_ and load those that are found.

template<class T, ManagedObjectAccess Access>
void esp::metadata::managers::AttributesManager<T, Access>::finalizeAttrPathsBeforeRegister(const AttribsPtr& attributes) const pure virtual

This function will be called to finalize attributes' paths before registration, moving fully qualified paths to the appropriate hidden attribute fields. This can also be called without registration to make sure the paths specified in an attributes are properly configured.

Parameters
attributes The attributes to be filtered.

template<class T, ManagedObjectAccess Access>
void esp::metadata::managers::AttributesManager<T, Access>::filterAttribsFilenames(const AttribsPtr& attributes, const std::string& curRelPathName, const std::string& curFQPathName, const std::function<void(const std::string&)>& relPathSetter, const std::function<void(const std::string&)>& fqPathSetter) const protected

Called internally right before attribute registration. Filepaths in the json configs for Habitat SceneDatasets are specified relative to the location of the config in the file hierarchy. As the config is loaded, these filepaths will be fully qualified with absolute paths so that they can be easily found and consumed on command. However, saving fully qualified filepaths to JSON configs is undesirable.

Parameters
attributes The Configuration-backed attributes owning the filepath in question.
curRelPathName The currently set relative path filepath in the attributes
curFQPathName The currently set fully qualified filepath in the attributes
relPathSetter The relative filepath setter in the attributes
fqPathSetter The fully qualified filepath setter in the attributes

This function will examine the curRelPathName to see that it is a relative path in relation to the attributes' set filepath, and if not it will strip out the path information and resave the name to rePathSetter. It will query the passed curFQPathName to see that it is a fully qualified path to a file that exists, and if not it will add the attributes' filepath and resave it to fqPathSetter.

It is assumed that what is passed to this function always referneces a filepath, so if, for example, this is called on a render asset filepath, it is assumed that that filepath does not reference a primitive (non-file-based) asset.

template<class T, ManagedObjectAccess Access>
AttribsPtr esp::metadata::managers::AttributesManager<T, Access>::createFromJsonOrDefaultInternal(const std::string& filename, std::string& msg, bool registerObj) protected

Parameters
filename the file holding the configuration of the object
msg reference to progress message
registerObj whether the new object should be registered in library
Returns the created esp::metadata::attributes::AbstractAttributes.

template<class T, ManagedObjectAccess Access> template<class M>
void esp::metadata::managers::AttributesManager<T, Access>::setEnumStringFromJsonDoc(const io::JsonGenericValue& jsonConfig, const char* jsonTag, const std::string& mapName, bool saveUnspecified, const std::map<std::string, M>& mapToUse, const std::function<void(const std::string&)>& valueSetter) protected

This function is accessed by various attributes managers during loading. It provides a generic handler to look for a particular jsonTag in the given jsonConfig document, and if it is present it will attempt to find the value in the passed string-keyed mapToUse of enum config values. If the string is present it will return the string, otherwise it will return an empty string. The consumer of the function is responsible for only setting a config value if the string is not empty. The enum class should have the first value defined as Unspecified and given the value ID_UNDEFINED.

Parameters
jsonConfig The source json document
jsonTag The field to look for. If present expected to hold a string
mapName String map name, to be displayed if the value found in json is not found in mapToUse
saveUnspecified Whether to save the 'unspecified' string in value setter if no value is specified in json.
mapToUse String-keyed map of enum values supported for the field that corresponds to jsonTag. See attributes::AttributesEnumMaps.h/cpp.

template<class T, ManagedObjectAccess Access>
bool esp::metadata::managers::AttributesManager<T, Access>::setFilenameFromDefaultTag(const AttribsPtr& attributes, const std::string& srcAssetFilename, const std::function<void(const std::string&)>& filenameSetter) protected

Set a filename attribute to hold the appropriate data if the existing attribute's given path contains the sentinel tag value defined at esp::metadata::CONFIG_NAME_AS_ASSET_FILENAME. This will be specified in the Scene Dataset configuration file in the "default_attributes" tag for any attributes which consume file names to specify that the name specified as the instanced attributes should also be used to build the name of the specified asset. The tag value will be replaced by the attributes object's simplified handle, or if unable to be found, with an empty string.

Parameters
attributes The AbstractAttributes being worked with.
srcAssetFilename The given asset's stored filename to be queried for the specified tag. If the tag exists, replace it with the simplified handle given by the attributes (hence copy). If this DNE on disk, add file directory.
filenameSetter The function to set the filename appropriately for the given asset.
Returns Whether or not the final value residing within the attribute's asset filename exists or not.

If the given data does not contain the esp::metadata::CONFIG_NAME_AS_ASSET_FILENAME tag, this will attempt to find the file referenced in srcAssetFilename directly, first as it is given, and then by prefixing it with the current attributes' source file directory. If found it will call filenameSetter with the successful string.

This will only be called from the specified manager's initNewObjectInternal function, where the attributes is initially built from a default attributes (if such an attributes exists), since it is only within the default attributes that the tag in question would be specified.

template<class T, ManagedObjectAccess Access>
bool esp::metadata::managers::AttributesManager<T, Access>::setAttributesHandleFromDefaultTag(const AttribsPtr& attributes, const std::string& srcAssetHandle, const std::function<void(const std::string&)>& handleSetter) protected

Set an attribute that holds another attribute's handle to hold the appropriate data if the existing attribute's given path contains the sentinel tag value defined at esp::metadata::CONFIG_NAME_AS_ASSET_FILENAME. This will be used in the Scene Dataset configuration file in the "default_attributes" tag for any attributes which consume attributes handle names to specify that the name given as the instanced attributes should also be used to build the name of the specified asset's handle. The tag value will be replaced by the attributes object's simplified handle.

Parameters
attributes The AbstractAttributes being worked with.
srcAssetHandle The given asset's stored asset handle to be queried for the wildcard tag. If the tag exists, replace it with the simplified handle given by the attributes (hence copy). If this DNE on disk, add file directory.
handleSetter The function to set the handle appropriately for the given asset.
Returns Whether the sentinel tag was found or not in the handle specification.

This will only be called from the specified manager's initNewObjectInternal function, where the attributes is initially built from a default attributes (if such an attributes exists).
