Class StackConsistencyScope

java.lang.Object

org.ek9lang.compiler.symbols.Symbol

org.ek9lang.compiler.symbols.ScopedSymbol

org.ek9lang.compiler.symbols.StackConsistencyScope

All Implemented Interfaces:

Serializable, ICanCaptureVariables, IScope, IScopedSymbol, ISymbol, ITokenReference

public class StackConsistencyScope
extends ScopedSymbol
implements ICanCaptureVariables

Used when duplicate symbols are found, where we need to add a placeholder. So the result of the listening and processing can take place, symbols can still be put into some sort of scope; so they don't mess up other valid scopes. The phase will fail compilation with duplicate errors, but we will have ensured that other symbols and processing has been put somewhere.
