Detailed Description

Parses and evaluates a single expression of "virtual struct conditional grammar".

This is used internally by MatfiltResolveVstructs but is available to facilitate unit testing.

Member Function Documentation

void Evaluate ( const SdfPath &  nodeId,
const TfToken &  nodeInputId,
const SdfPath &  upstreamNodeId,
const TfToken &  upstreamNodeOutput,
const NdrTokenVec &  shaderTypePriority,
HdMaterialNetwork2 &  network 
) const

Runs the conditional actions specified by the parsed inputExpr.

Because this evaluates the conditional actions (connect, ignore, set constant, copy upstream parameter value), this is sent the context of the current connected nodes as well as the mutable network to directly change.
