usdrt::UsdSchemaBase

Functions

usdrt::DestructionSchemaDestructibleBaseAPI::GetPath: Return the SdfPath to this schema object's held prim.
usdrt::DestructionSchemaDestructibleBaseAPI::GetPrim: Return this schema object's held prim.
usdrt::UsdSchemaBase::UsdSchemaBase: Construct and store prim as the held prim.
usdrt::UsdSchemaBase::UsdSchemaBase: Construct and store for the same prim held by otherSchema .
usdrt::UsdSchemaBase::operator bool: Return true if the held prim is valid.
usdrt::UsdSchemaBase::~UsdSchemaBase: Destructor.

Variables

usdrt::UsdSchemaBase::schemaType: Compile time constant representing what kind of schema this class is.

class UsdSchemaBase

Base class for all Usd Schemas. Schema objects hold a UsdPrim m_prim and an SdfPath m_primPath and provide an additional layer of specific API.

Create vs Get Property Methods

For a UsdAttribute named “points” defined in a schema class, you will find two access methods in the schema class in C++ and python:

GetPointsAttr() returns a UsdAttribute and is used in read-only cases.

CreatePointsAttr() returns a UsdAttribute, and also creates it on the prim if it doesn’t exist. There is no change if the attribute already exists.
