java.lang.Object

Enclosing class:

MutatedOnlyVariables

final class MutatedOnlyVariables.Collector
extends Object

One source's collection. Callables nest (a dynamic class or function inside a method), so their returning variables are kept on a stack and an assignment is matched against the innermost.

Method Summary

Modifier and Type	Method	Description
(package private) void	assignment(EK9Parser.AssignmentStatementContext ctx)	A pointer assignment to the innermost callable's returning variable is a source of what it returns.
(package private) void	enterCallable(ISymbol symbol)	A method, operator, function or dynamic function is entered; only one with a returning variable is followed.
(package private) void	exitCallable()
(package private) void	variableDeclared(EK9Parser.VariableDeclarationContext ctx, ISymbol symbol)

void variableDeclared(EK9Parser.VariableDeclarationContext ctx,

void assignment(EK9Parser.AssignmentStatementContext ctx)

A pointer assignment to the innermost callable's returning variable is a source of what it returns.
