Detailed Description

Holder for Houdini-specific layer information.

Definition at line 56 of file houdiniLayerInfo.h.

Constructor & Destructor Documentation

UsdHoudiniHoudiniLayerInfo::UsdHoudiniHoudiniLayerInfo ( const UsdPrim prim = UsdPrim())

Construct a UsdHoudiniHoudiniLayerInfo on UsdPrim prim . Equivalent to UsdHoudiniHoudiniLayerInfo::Get(prim.GetStage(), prim.GetPath()) for a valid prim, but will not immediately throw an error for an invalid prim

Definition at line 70 of file houdiniLayerInfo.h.

UsdHoudiniHoudiniLayerInfo::UsdHoudiniHoudiniLayerInfo ( const UsdSchemaBase schemaObj)

Construct a UsdHoudiniHoudiniLayerInfo on the prim held by schemaObj . Should be preferred over UsdHoudiniHoudiniLayerInfo(schemaObj.GetPrim()), as it preserves SchemaBase state.

Definition at line 78 of file houdiniLayerInfo.h.

Member Function Documentation

UsdSchemaKind UsdHoudiniHoudiniLayerInfo::_GetSchemaKind ( ) const

Returns the kind of schema this class belongs to.

See Also

Reimplemented from UsdSchemaBase.

static UsdHoudiniHoudiniLayerInfo UsdHoudiniHoudiniLayerInfo::Define ( const UsdStagePtr &  stage,
const SdfPath path 

Attempt to ensure a UsdPrim adhering to this schema at path is defined (according to UsdPrim::IsDefined()) on this stage.

If a prim adhering to this schema at path is already defined on this stage, return that prim. Otherwise author an SdfPrimSpec with specifier == SdfSpecifierDef and this schema's prim type name for the prim at path at the current EditTarget. Author SdfPrimSpec s with specifier == SdfSpecifierDef and empty typeName at the current EditTarget for any nonexistent, or existing but not Defined ancestors.

The given path must be an absolute prim path that does not contain any variant selections.

If it is impossible to author any of the necessary PrimSpecs, (for example, in case path cannot map to the current UsdEditTarget's namespace) issue an error and return an invalid UsdPrim.

Note that this method may return a defined prim whose typeName does not specify this schema class, in case a stronger typeName opinion overrides the opinion at the current EditTarget.

static UsdHoudiniHoudiniLayerInfo UsdHoudiniHoudiniLayerInfo::Get ( const UsdStagePtr &  stage,
const SdfPath path 

Return a UsdHoudiniHoudiniLayerInfo holding the prim adhering to this schema at path on stage. If no prim exists at path on stage, or if the prim at that path does not adhere to this schema, return an invalid schema object. This is shorthand for the following:

static const TfTokenVector& UsdHoudiniHoudiniLayerInfo::GetSchemaAttributeNames ( bool  includeInherited = true)

Return a vector of names of all pre-declared attributes for this schema class and all its ancestor classes. Does not include attributes that may be authored by custom/extended methods of the schemas involved.
