Abstract interface for querying and mutating a material network.
Parses and evaluates a single expression of "virtual struct conditional grammar".
Token for efficient comparison, assignment, and hashing of known strings.

void Evaluate(const TfToken &nodeId, const TfToken &nodeInputId, const TfToken &upstreamNodeId, const TfToken &upstreamNodeOutput, const NdrTokenVec &shaderTypePriority, HdMaterialNetworkInterface *networkInterface) const
Runs the conditional actions specified by the parsed inputExpr.
