Detailed Description

Defines a base-class type applied schema that all applied schema that provide the ParticleField position data will automatically apply. The purpose of this base class is to allow validation to enforce that an applied schema that defines position is always present for a ParticleField.

The number of positions provided is also used to determine the number of particle in the ParticleField. If no position data is present, then the ParticleField contains no particles. Any other per-particle data provided, such as scale or orientation, is truncated if too long, or if too short the entire data set will be discarded. For these other per-particle data fields, if no data is provided, or it is discarded then its default value will be used.

Constructor & Destructor Documentation

UsdVolParticleFieldPositionBaseAPI::UsdVolParticleFieldPositionBaseAPI ( const UsdPrim & prim = UsdPrim() )

inlineexplicit

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

Definition at line 64 of file particleFieldPositionBaseAPI.h.

UsdVolParticleFieldPositionBaseAPI::UsdVolParticleFieldPositionBaseAPI ( const UsdSchemaBase & schemaObj )

inlineexplicit

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

Definition at line 72 of file particleFieldPositionBaseAPI.h.

virtual USDVOL_API UsdVolParticleFieldPositionBaseAPI::~UsdVolParticleFieldPositionBaseAPI ( )

virtual

Destructor.

Member Function Documentation

USDVOL_API UsdSchemaKind UsdVolParticleFieldPositionBaseAPI::_GetSchemaKind ( ) const

overrideprotectedvirtual

Returns the kind of schema this class belongs to.

See Also: UsdSchemaKind

Reimplemented from UsdAPISchemaBase.

static USDVOL_API UsdVolParticleFieldPositionBaseAPI UsdVolParticleFieldPositionBaseAPI::Apply ( const UsdPrim & prim )

static

Applies this single-apply API schema to the given prim. This information is stored by adding "ParticleFieldPositionBaseAPI" to the token-valued, listOp metadata apiSchemas on the prim.

Returns: A valid UsdVolParticleFieldPositionBaseAPI object is returned upon success. An invalid (or empty) UsdVolParticleFieldPositionBaseAPI object is returned upon failure. See UsdPrim::ApplyAPI() for conditions resulting in failure.

static USDVOL_API bool UsdVolParticleFieldPositionBaseAPI::CanApply	(	const UsdPrim &	prim,
		std::string *	whyNot = `nullptr`
	)

static

Returns true if this single-apply API schema can be applied to the given prim. If this schema can not be a applied to the prim, this returns false and, if provided, populates whyNot with the reason it can not be applied.

Note that if CanApply returns false, that does not necessarily imply that calling Apply will fail. Callers are expected to call CanApply before calling Apply if they want to ensure that it is valid to apply a schema.

static USDVOL_API UsdVolParticleFieldPositionBaseAPI UsdVolParticleFieldPositionBaseAPI::Get	(	const UsdStagePtr &	stage,
		const SdfPath &	path
	)

static

Return a UsdVolParticleFieldPositionBaseAPI 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:

UsdVolParticleFieldPositionBaseAPI(stage->GetPrimAtPath(path));

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

static

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.
