GetExpressionBuilder()

SDF_API SdfVariableExpression::Builder GetExpressionBuilder

(

)

const

Return SdfVariableExpression::Builder for this node.

This can be used when creating expressions using the various SdfVariableExpression API for building expressions without incurring extra overhead from parsing into an SdfVariableExpression.
