Constructor Detail

MemberAccessExpressionNode

public MemberAccessExpressionNode(ExpressionNodeBase left,
                          IASToken operatorToken,
                          ExpressionNodeBase right)

Constructor.

Parameters:

left - the expression on the left of the member access (the object)

operatorToken - the ASToken holding the member access operator (".")

right - the expression on the right of the member access (the member)

MemberAccessExpressionNode

public MemberAccessExpressionNode(MemberAccessExpressionNode other)

Copy constructor.

Parameters:

other - The node to copy.

Method Detail

getNodeID

public ASTNodeID getNodeID()

Description copied from interface: IASNode

Get the opcode of this node

Specified by:

getNodeID in interface IASNode

Returns:

the opcode - this is one of the constants defined in ASTConstants

resolve

public IDefinition resolve(ICompilerProject project)

Description copied from interface: IExpressionNode

If this expression is statically known to refer to a definition return a reference to that definition. In many cases this will return the same definition as resolveType, but when an identifier resolves to an member variable or member function of a class, this method will return the IDefinition for the member variable or member function not the definition for the type of the member variable or the member function.

Specified by:

resolve in interface IExpressionNode

Overrides:

resolve in class ExpressionNodeBase

Parameters:

project - The ICompilerProject to use to do lookups.

Returns:

The IDefinition this expression refers to.

resolveType

public ITypeDefinition resolveType(ICompilerProject project)

Description copied from interface: IExpressionNode

The type of the result of this expression. This method returns the IDefinition representing the type that is the result of this expression. This can differ from the IDefinition you get from resolve(), such as when called on a FunctionCallNode: resolve() will return the IDefinition for the Function, whereas resolveType() will return the return type of the Function.

Specified by:

resolveType in interface IExpressionNode

Overrides:

resolveType in class BinaryOperatorNodeBase

Parameters:

project - The ICompilerProject to use to do lookups.

Returns:

The ITypeDefinition of the type this expression results in.

isDynamicExpression

public boolean isDynamicExpression(ICompilerProject project)

Description copied from interface: IExpressionNode

Does this expression evaluate to a dynamic value

Specified by:

isDynamicExpression in interface IExpressionNode

Overrides:

isDynamicExpression in class ExpressionNodeBase

Parameters:

project - The ICompilerProject to use to do lookups.

Returns:

true if we evaluate to something dynamic

copy

protected MemberAccessExpressionNode copy()

Description copied from class: ExpressionNodeBase

Copy the ExpressionNodeBase and its subtree.

Specified by:

copy in class ExpressionNodeBase

Returns:

a new ExpressionNodeBase that represents the same content as the original node

getMName

public Name getMName(ICompilerProject project)

Description copied from class: ExpressionNodeBase

Gets the AET Name object to be used for an expression.

For all expression nodes except for the identifier nodes and member access nodes, this method returns null.

This is the method that the code generator calls to determine what name to emit into the ABC file. It will handle resolving the identifier if necessary and generating the appropriate qname or multiname.

Overrides:

getMName in class ExpressionNodeBase

Parameters:

project - The ICompilerProject to use to do lookups.

Returns:

A AET Name object.

computeNamespaceReference

public INamespaceReference computeNamespaceReference()

Description copied from class: ExpressionNodeBase

Generate an INamespaceReference that can serve as the namespace reference for something like a namespace initializer.

Overrides:

computeNamespaceReference in class ExpressionNodeBase

Returns:

An INamespaceReference that represents this expression node or null.

getOperator

public IOperatorNode.OperatorType getOperator()

Description copied from interface: IOperatorNode

Returns the type of the operator that is referenced from this expression

Specified by:

getOperator in interface IOperatorNode

Returns:

the operator that we're using

getOperatorText

public String getOperatorText()

Overrides:

getOperatorText in class OperatorNodeBase

getDisplayString

public String getDisplayString()

Description copied from interface: IMemberAccessExpressionNode

Returns a string representation of this member access node, including the operator.

Specified by:

getDisplayString in interface IMemberAccessExpressionNode

Returns:

A String such as "a.b".

isSuper

public boolean isSuper(ExpressionNodeBase node)

stemIsPackage

public boolean stemIsPackage()

Determine if the left side of this Node refers to a package name

Returns:

true if the left side is a package name

setStemAsPackage

public void setStemAsPackage(boolean b)

Tell the MemberAccessExpression that it's "stem" ('a.b' in 'a.b.Foo') should always be treated as a package, regardless of whether it is imported or not. This is needed by MXML because sometimes it does not require users to import a package before using it as a package (such as in MXMLClassNode).

isMemberReference

public boolean isMemberReference(IASNode node)

Is the given node this node's member reference?

Parameters:

node - - the node of interest.

Returns:

true iff node is this node's member reference.
