class UsdSchemaRegistry

Detailed Description

The base class for all typed schemas (those that can impart a typeName to a UsdPrim), and therefore the base class for all concrete, instantiable "IsA" schemas.

UsdTyped implements a typeName-based query for its override of UsdSchemaBase::_IsCompatible(). It provides no other behavior.

Constructor & Destructor Documentation

UsdTyped::UsdTyped ( const UsdPrim prim = UsdPrim())

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

Definition at line 73 of file typed.h.

UsdTyped::UsdTyped ( const UsdSchemaBase schemaObj)

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

Definition at line 81 of file typed.h.

virtual USD_API UsdTyped::~UsdTyped ( )


Member Function Documentation

USD_API bool UsdTyped::_IsCompatible ( ) const

Subclasses may override _IsCompatible to do specific compatibility checking with the given prim, such as type compatibility or value compatibility. This check is performed when clients invoke the explicit bool operator.

Reimplemented from UsdSchemaBase.

static USD_API UsdTyped UsdTyped::Get ( const UsdStagePtr &  stage,
const SdfPath path 

Return a UsdTyped 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 USD_API const TfTokenVector& UsdTyped::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.
