Constructor & Destructor Documentation

HdarSystemSchema::HdarSystemSchema ( HdContainerDataSourceHandle  container )

inline

Retrieves a container data source with the schema's default name token "assetResolution" from the parent container and constructs a HdarSystemSchema instance. Because the requested container data source may not exist, the result should be checked with IsDefined() or a bool comparison before use.

Member Function Documentation

static HDAR_API HdContainerDataSourceHandle HdarSystemSchema::BuildRetained ( const HdResolverContextDataSourceHandle &  resolverContext )

static

Deprecated:

Use Builder instead.

Builds a container data source which includes the provided child data sources. Parameters with nullptr values are excluded. This is a low-level interface. For cases in which it's desired to define the container with a sparse set of child fields, the Builder class is often more convenient and readable.

static HDAR_API const HdDataSourceLocator& HdarSystemSchema::GetDefaultLocator ( )

static

Returns an HdDataSourceLocator (relative to the prim-level data source) where the container representing this schema is found by default.

static HDAR_API HdarSystemSchema HdarSystemSchema::GetFromParent ( const HdContainerDataSourceHandle &  fromParentContainer )

static

Retrieves a container data source with the schema's default name token "assetResolution" from the parent container and constructs a HdarSystemSchema instance. Because the requested container data source may not exist, the result should be checked with IsDefined() or a bool comparison before use.

static HDAR_API HdContainerDataSourceHandle HdarSystemSchema::GetFromPath ( HdSceneIndexBaseRefPtr const &  inputScene, SdfPath const &  fromPath, SdfPath *  foundAtPath  )

static

Evaluates the asset resolution "system" data source for fromPath.

If found, the return value will be non-null and foundAtPath will contain the path at which the non-null result was found. Otherwise, this returns null.

This operation will be linear in the length of fromPath.

HDAR_API HdResolverContextDataSourceHandle HdarSystemSchema::GetResolverContext

(

)

const

static HDAR_API const TfToken& HdarSystemSchema::GetSchemaToken ( )

static

Returns a token where the container representing this schema is found in a container by default.
