All Implemented Interfaces:

Enclosing interface:

JavaScriptTranslatorToCAst

public static class JavaScriptTranslatorToCAst.MemberDestructuringContext<C extends JavaScriptTranslatorToCAst.WalkContext<C,T>, T>
extends Object
implements JavaScriptTranslatorToCAst.WalkContext<C,T>

Used to determine the value to be passed as the 'this' argument for a function call. This is needed since in JavaScript, you can write a call e(...) where e is some arbitrary expression, and in the case where e is a property access like e'.f, we must discover that the value of expression e' is passed as the 'this' parameter.

The general strategy is to store the value of the expression passed as the 'this' parameter in baseVar, and then to use baseVar as the actual argument sub-node for the CAst call node

default T	getContinueFor(String label)	for a 'continue' style goto, return the control flow target
default List<CAstNode>	getNameDecls()
default CAstNodeTypeMapRecorder	getNodeTypeMap()	for recording types of nodes
default Map<CAstNode, Collection<CAstEntity>>	getScopedEntities()	get a mapping from CAstNodes to the scoped entities (e.g.
default CAstSourcePositionRecorder	pos()	for recording source positions
