Public functions

auto createObject(const std::string& semanticConfigFilename, bool registerTemplate = true) -> attributes::SemanticAttributes::ptr override: Creates an instance of a semantic attributes used to govern which calculations are performed by the PBR shader (such as Image-based Lighting and/or specific PBR layer calculations), as well as to provide some user-configurable shader-wide control values.
void setValsFromJSONDoc(attributes::SemanticAttributes::ptr attribs, const io::JsonGenericValue& jsonConfig) override: Method to take an existing attributes and set its values from passed json config file.
auto createEmptyRegionAttributes(const std::string& handle) -> attributes::SemanticVolumeAttributes::ptr: This will return a attributes::SemanticVolumeAttributes object with passed handle.

Protected functions

auto createRegionAttributesFromJSON(const io::JsonGenericValue& jCell) -> attributes::SemanticVolumeAttributes::ptr: Used Internally. Create a esp::metadata::attributes::SemanticVolumeAttributes object from the passed JSON doc.
void setSemanticVolumeAttributesFromJson(const attributes::SemanticVolumeAttributes::ptr& attributes, const io::JsonGenericValue& jCell): Populate an existing metadata::attributes::SemanticVolumeAttributes from a JSON config.
auto initNewObjectInternal(const std::string& handleName, bool builtFromConfig) -> attributes::SemanticAttributes::ptr override: Used Internally. Create and configure newly-created attributes with any default values, before any specific values are set.
void deleteObjectInternalFinalize(int templateID, const std::string& templateHandle) override: This method will perform any necessary updating that is attributesManager-specific upon template removal, such as removing a specific template handle from the list of file-based template handles in ObjectAttributesManager. This should only be called esp::core::ManagedContainerBase.
auto preRegisterObjectFinalize(attributes::SemanticAttributes::ptr object, const std::string& objectHandle, bool forceRegistration) -> core::managedContainers::ManagedObjectPreregistration override: Not required for this manager.
void postRegisterObjectHandling(int objectID, const std::string& objectHandle) override: Not required for this manager.
void resetFinalize() override: Any physics-attributes-specific resetting that needs to happen on reset.

Function documentation

attributes::SemanticAttributes::ptr esp::metadata::managers::SemanticAttributesManager::createObject(const std::string& semanticConfigFilename, bool registerTemplate = true) override

Creates an instance of a semantic attributes used to govern which calculations are performed by the PBR shader (such as Image-based Lighting and/or specific PBR layer calculations), as well as to provide some user-configurable shader-wide control values.

Parameters
semanticConfigFilename	The location of the Semantic Configuratioo.
registerTemplate	whether to add this template to the library. If the user is going to edit this template, this should be false - any subsequent editing will require re-registration. Defaults to true. If specified as true, then this function returns a copy of the registered template.
Returns	a reference to the physics simulation meta data object parsed from the specified configuration file.

If a template exists with this handle, this existing template will be overwritten with the newly created one if registerTemplate is true.

void esp::metadata::managers::SemanticAttributesManager::setValsFromJSONDoc(attributes::SemanticAttributes::ptr attribs, const io::JsonGenericValue& jsonConfig) override

Method to take an existing attributes and set its values from passed json config file.

Parameters
attribs	(out) an existing attributes to be modified.
jsonConfig	json document to parse

attributes::SemanticVolumeAttributes::ptr esp::metadata::managers::SemanticAttributesManager::createRegionAttributesFromJSON(const io::JsonGenericValue& jCell) protected

Used Internally. Create a esp::metadata::attributes::SemanticVolumeAttributes object from the passed JSON doc.

Parameters
jCell	JSON object containing the description of the semantic retion
Returns	the constructed esp::metadata::attributes::SemanticVolumeAttributes object

void esp::metadata::managers::SemanticAttributesManager::setSemanticVolumeAttributesFromJson(const attributes::SemanticVolumeAttributes::ptr& attributes, const io::JsonGenericValue& jCell) protected

Populate an existing metadata::attributes::SemanticVolumeAttributes from a JSON config.

Parameters
attributes	(out) the attributes to populate with JSON values
jCell	JSON document to parse to populate the metadata::attributes::SemanticVolumeAttributes

attributes::SemanticAttributes::ptr esp::metadata::managers::SemanticAttributesManager::initNewObjectInternal(const std::string& handleName, bool builtFromConfig) override protected

Used Internally. Create and configure newly-created attributes with any default values, before any specific values are set.

Parameters
handleName	handle name to be assigned to attributes
builtFromConfig	Whether this SemanticAttributes is being built from a config file (i.e. handleName is the name of a configuration file) or from some other source.
Returns	Newly created but unregistered SemanticAttributes pointer, with only default values set.

void esp::metadata::managers::SemanticAttributesManager::deleteObjectInternalFinalize(int templateID, const std::string& templateHandle) override protected

This method will perform any necessary updating that is attributesManager-specific upon template removal, such as removing a specific template handle from the list of file-based template handles in ObjectAttributesManager. This should only be called esp::core::ManagedContainerBase.

Parameters
templateID	the ID of the template to remove
templateHandle	the string key of the attributes desired.

core::managedContainers::ManagedObjectPreregistration esp::metadata::managers::SemanticAttributesManager::preRegisterObjectFinalize(attributes::SemanticAttributes::ptr object, const std::string& objectHandle, bool forceRegistration) override protected

Not required for this manager.

Parameters
object	the managed object to be registered
objectHandle	the name to register the managed object with. Expected to be valid.
forceRegistration	Should register object even if conditional registration checks fail.
Returns	Whether the preregistration has succeeded and what handle to use to register the object if it has.

This method will perform any essential updating to the managed object before registration is performed. If this updating fails, registration will also fail.

void esp::metadata::managers::SemanticAttributesManager::postRegisterObjectHandling(int objectID, const std::string& objectHandle) override protected
