Detailed Description

MaterialXConfigAPI is an API schema that provides an interface for storing information about the MaterialX environment.

Initially, it only exposes an interface to record the MaterialX library version that data was authored against. The intention is to use this information to allow the MaterialX library to perform upgrades on data from prior MaterialX versions.

Constructor & Destructor Documentation

◆ UsdMtlxMaterialXConfigAPI() [1/2]

UsdMtlxMaterialXConfigAPI ( const UsdPrim & prim = UsdPrim() )

inlineexplicit

Construct a UsdMtlxMaterialXConfigAPI on UsdPrim prim .

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

Definition at line 59 of file materialXConfigAPI.h.

◆ UsdMtlxMaterialXConfigAPI() [2/2]

UsdMtlxMaterialXConfigAPI ( const UsdSchemaBase & schemaObj )

inlineexplicit

Construct a UsdMtlxMaterialXConfigAPI on the prim held by schemaObj .

Should be preferred over UsdMtlxMaterialXConfigAPI(schemaObj.GetPrim()), as it preserves SchemaBase state.

Definition at line 67 of file materialXConfigAPI.h.

◆ ~UsdMtlxMaterialXConfigAPI()

virtual USDMTLX_API ~UsdMtlxMaterialXConfigAPI ( )

virtual

Destructor.

Member Function Documentation

◆ _GetSchemaKind()

USDMTLX_API UsdSchemaKind _GetSchemaKind ( ) const

overrideprotectedvirtual

Returns the kind of schema this class belongs to.

See also: UsdSchemaKind

Reimplemented from UsdAPISchemaBase.

◆ Apply()

static USDMTLX_API UsdMtlxMaterialXConfigAPI Apply ( const UsdPrim & prim )

static

Applies this single-apply API schema to the given prim.

This information is stored by adding "MaterialXConfigAPI" to the token-valued, listOp metadata apiSchemas on the prim.

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

See also: UsdPrim::GetAppliedSchemas(); UsdPrim::HasAPI(); UsdPrim::CanApplyAPI(); UsdPrim::ApplyAPI(); UsdPrim::RemoveAPI()

◆ CanApply()

static USDMTLX_API bool 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.

See also: UsdPrim::GetAppliedSchemas(); UsdPrim::HasAPI(); UsdPrim::CanApplyAPI(); UsdPrim::ApplyAPI(); UsdPrim::RemoveAPI()

◆ CreateConfigMtlxVersionAttr()

USDMTLX_API UsdAttribute CreateConfigMtlxVersionAttr	(	VtValue const &	defaultValue = `VtValue()`,
		bool	writeSparsely = `false`
	)		const

See GetConfigMtlxVersionAttr(), and also Create vs Get Property Methods for when to use Get vs Create.

If specified, author defaultValue as the attribute's default, sparsely (when it makes sense to do so) if writeSparsely is true - the default for writeSparsely is false.

◆ Get()

static USDMTLX_API UsdMtlxMaterialXConfigAPI Get	(	const UsdStagePtr &	stage,
		const SdfPath &	path
	)

static

Return a UsdMtlxMaterialXConfigAPI 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:

UsdMtlxMaterialXConfigAPI(stage->GetPrimAtPath(path));

◆ GetConfigMtlxVersionAttr()

USDMTLX_API UsdAttribute GetConfigMtlxVersionAttr ( ) const

MaterialX library version that the data has been authored against.

Defaults to 1.38 to allow correct verisoning of old files.


Declaration	`string config:mtlx:version = "1.38"`
C++ Type	std::string
Usd Type	SdfValueTypeNames->String

◆ GetSchemaAttributeNames()

static USDMTLX_API const TfTokenVector & 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.
