Interface InputVarGen

All Superinterfaces:

LocalVarGen<JitInputVar>, ValGen<JitInputVar>, VarGen<JitInputVar>

All Known Implementing Classes:

SubInputVarGen, WholeInputVarGen

public interface InputVarGen
extends LocalVarGen<JitInputVar>

The generator for a local variable that is input to the passage.

This prohibits generation of code to write the variable.
