Constructor Summary

EMethod(SourceSpan optSpan, String docComment, String verb, Pattern[] patterns, EExpr returnGuard, EExpr body)
Enabled: The constructor interns the verb

EMethod(SourceSpan optSpan, String docComment, String verb, Pattern[] patterns, EExpr returnGuard, EExpr body, int localCount)
Enabled: Create the EMethod with the number of locals to allocate to a stack frame.

Enabled: Create the EMethod with the number of locals to allocate to a stack frame. This method assumes the verb is interned.

Method Detail

welcome

public Object welcome(ETreeVisitor visitor)

Enabled:
