Class MXMLBindingDirectiveHelper

java.lang.Object

org.apache.flex.compiler.internal.codegen.databinding.MXMLBindingDirectiveHelper

public class MXMLBindingDirectiveHelper
extends Object

Keeps track of all the Data Bindings in an MXML file and helps with codegen for data binding. This class is closely linked with MXMLDocumentDirectiveProcessor - they both call each other and could be merged. They are separate just to manage size and complexity. TODO: Document the runtime dependencies on SDK add problem reporting. Cases not yet working: bind to function, xml, xml list, array Improve code gen don't make getter functions when not needed share getters when possible known bugs: Generated traits not in mx_internal

Methods

Modifier and Type	Method and Description
InstructionList	getConstructorCode() get the instruction list for code to be added to constructor to set up data binding.
void	visitNode(IMXMLBindingNode node) Visit an IMXMLBindingNode - this node has explicit source and destination expressions instead of the destination being determined by the nodes location in the AST, as in the IMXMLInstanceNode version above
BindingInfo	visitNode(IMXMLDataBindingNode node) host should visit all the databinding nodes before trying to codegen them

MXMLBindingDirectiveHelper

public MXMLBindingDirectiveHelper(MXMLClassDirectiveProcessor ddp,
                          IABCVisitor emitter)

Method Detail

visitNode

public BindingInfo visitNode(IMXMLDataBindingNode node)

host should visit all the databinding nodes before trying to codegen them

visitNode

public void visitNode(IMXMLBindingNode node)

Visit an IMXMLBindingNode - this node has explicit source and destination expressions instead of the destination being determined by the nodes location in the AST, as in the IMXMLInstanceNode version above

Parameters:

node - the Binding Node to vist

getConstructorCode

public InstructionList getConstructorCode()

get the instruction list for code to be added to constructor to set up data binding. This is the main entry point for codegen of databindings This function must be called only once, after then entire document has been traversed.

Returns:

the InstructionList the instruction list for code to be added to constructor
