Package org.ek9lang.compiler.symbols

Class CaptureScope

java.lang.Object

org.ek9lang.compiler.symbols.SymbolTable

org.ek9lang.compiler.symbols.LocalScope

org.ek9lang.compiler.symbols.CaptureScope

All Implemented Interfaces:

Serializable, IScope

public class CaptureScope
extends LocalScope

Used to actually hold the captured symbols. Note that the resolution out to the enclosing scope is switched on and off. This switching is based on entering and exiting the 'capture' via the antlr listeners. It is important because on entering the capture scope it must be possible to resolve varaiables in the enclosing Blocks before, so that variables can be captured). But on exiting the capture scope, the resolution must then only be within this scope and must not look outside to the enclosing scope.

equals

public boolean equals(Object o)

Overrides:

equals in class LocalScope

hashCode

public int hashCode()

Overrides:

hashCode in class LocalScope

clone

public CaptureScope clone(IScope withParentAsAppropriate)

Specified by:

clone in interface IScope

Overrides:

clone in class LocalScope

cloneIntoCaptureScope

public CaptureScope cloneIntoCaptureScope(CaptureScope newCopy)

Clones the content of this into the new copy.

define

public void define(ISymbol symbol)

Description copied from interface: IScope

Define a Symbol in this scope.

Specified by:

define in interface IScope

Overrides:

define in class SymbolTable

setOpenToEnclosingScope

public void setOpenToEnclosingScope(boolean openToEnclosingScope)

resolveWithEnclosingScope

public Optional<ISymbol> resolveWithEnclosingScope(SymbolSearch search)

Description copied from class: SymbolTable

This class is the root and so there is no enclosing scope. subclasses will override to provide the scope that encloses them

Overrides:

resolveWithEnclosingScope in class LocalScope

resolveMatchingMethodsInEnclosingScope

protected MethodSymbolSearchResult resolveMatchingMethodsInEnclosingScope(MethodSymbolSearch search,
 MethodSymbolSearchResult result)

Description copied from class: SymbolTable

There are no supers so this will not add any methods.

Overrides:

resolveMatchingMethodsInEnclosingScope in class LocalScope
