Class FunctionObjectNode

java.lang.Object

org.apache.flex.compiler.common.SourceLocation

org.apache.flex.compiler.internal.tree.as.NodeBase

org.apache.flex.compiler.internal.tree.as.FixedChildrenNode

org.apache.flex.compiler.internal.tree.as.ExpressionNodeBase

org.apache.flex.compiler.internal.tree.as.FunctionObjectNode

All Implemented Interfaces:

ISourceLocation, IASNode, IExpressionNode, IFunctionObjectNode

public class FunctionObjectNode
extends ExpressionNodeBase
implements IFunctionObjectNode

An anonymous function (e.g. function() {...}) is an expression, but acts like a function definition where scopes are concerned. We'll implement this hybrid construct by wrapping a regular FunctionNode in an ExpressionNodeBase-based wrapper.

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

getChildCount

public int getChildCount()

Description copied from interface: IASNode

Get the number of children

Specified by:

getChildCount in interface IASNode

Overrides:

getChildCount in class NodeBase

Returns:

the number of children

getChild

public IASNode getChild(int i)

Description copied from interface: IASNode

Get a particular child of this node

Specified by:

getChild in interface IASNode

Overrides:

getChild in class NodeBase

Parameters:

i - the child's index

Returns:

the specified child

setChildren

protected void setChildren(boolean fillInOffsets)

Description copied from class: NodeBase

If this node has custom children (names, arguments, etc), shove them into the list of children. Used during parsing.

Overrides:

setChildren in class NodeBase

analyze

protected void analyze(EnumSet<PostProcessStep> set,
           ASScope scope,
           Collection<ICompilerProblem> problems)

Overrides:

analyze in class NodeBase

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 ExpressionNodeBase

Parameters:

project - The ICompilerProject to use to do lookups.

Returns:

The ITypeDefinition of the type this expression results in.

copy

protected FunctionObjectNode 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

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

getFunctionNode

public FunctionNode getFunctionNode()

Description copied from interface: IFunctionObjectNode

Get the associated function node

Specified by:

getFunctionNode in interface IFunctionObjectNode

Returns:

function node
