Function Documentation

TF_DECLARE_PUBLIC_TOKENS	(	UsdCollectionMembershipQueryTokens	,
		USD_API	,
		USD_COLLECTION_MEMBERSHIP_QUERY_TOKENS
	)

USD_API std::set<UsdObject> UsdComputeIncludedObjectsFromCollection	(	const UsdCollectionMembershipQuery &	query,
		const UsdStageWeakPtr &	stage,
		const Usd_PrimFlagsPredicate &	pred = UsdPrimDefaultPredicate
	)

Returns all the usd objects that satisfy the predicate, pred in the collection represented by the UsdCollectionMembershipQuery object, query.

The results depends on the load state of the UsdStage, stage.

USD_API SdfPathSet UsdComputeIncludedPathsFromCollection	(	const UsdCollectionMembershipQuery &	query,
		const UsdStageWeakPtr &	stage,
		const Usd_PrimFlagsPredicate &	pred = UsdPrimDefaultPredicate
	)

Returns all the paths that satisfy the predicate, pred in the collection represented by the UsdCollectionMembershipQuery object, query.

The result depends on the load state of the UsdStage, stage.

USD_API SdfPathExpression UsdComputePathExpressionFromCollectionMembershipQueryRuleMap

(

Usd_CollectionMembershipQueryBase::PathExpansionRuleMap const &

ruleMap

)

Compute an SdfPathExpression that matches the same paths as ruleMap. The resulting SdfPathExpression is always complete (see SdfPathExpression::IsComplete()) and never contains predicates.
