Detailed Description

Disjunction of prim flag predicate terms.

Usually clients will implicitly create disjunctions by ||-ing together flag predicate terms. For example:

// Get all deactivated or undefined children.
prim.GetFilteredChildren(!UsdPrimIsActive || !UsdPrimIsDefined)

See primFlags.h for more details.

Member Function Documentation

USD_API class Usd_PrimFlagsConjunction Usd_PrimFlagsDisjunction::operator!

(

)

const

Negate this disjunction, producing a disjunction by De Morgan's law. For instance:

!(UsdPrimIsLoaded || UsdPrimIsModel)

Will negate the disjunction in parens to produce a conjunction equivalent to:

(!UsdPrimIsLoaded && !UsdPrimIsModel)

Every expression may be formulated as either a disjunction or a conjuction, but allowing both affords increased expressiveness.

Usd_PrimFlagsDisjunction& Usd_PrimFlagsDisjunction::operator|= ( Usd_Term  term )

inline

Add an additional term to this disjunction.
