Interface IFunctionCallNode

All Superinterfaces:

IASNode, IExpressionNode, ISourceLocation

All Known Implementing Classes:

FunctionCallNode

public interface IFunctionCallNode
extends IExpressionNode

An AST node representing a function call. It may be a constructor call.

The typical shape of this node is:

 IFunctionCallNode 
   IExpressionNode   <-- getNameNode()
   IContainerNode    <-- getArgumentsContainerNode()
     IExpressionNode <-- getArgumentNodes()[0]
     IExpressionNode <-- getArgumentNodes()[1]
     ...
 

For example, f(a, b) is represented as

 IFunctionCallNode
   IIdentifierNode "f"
   IContainerNode
     IIdentifierNode "a"
     IIdentiferNode "b"
 

For a constructor call, the first child represents the new keyword:

 IFunctionCallNode 
   IKeywordNode      <-- getNewKeywordNode()
   IExpressionNode   <-- getNameNode()
   IContainerNode    <-- getArgumentsContainerNode()
     IExpressionNode <-- getArgumentNodes()[0]
     IExpressionNode <-- getArgumentNodes()[1]
     ...
 

For example, new C(a, b) is represented as

 IFunctionCallNode
   IKeywordNode "new"
   IIdentifierNode "C"
   IContainerNode
     IIdentifierNode "a"
     IIdentiferNode "b"

Method Detail

getNameNode

IExpressionNode getNameNode()

The expression being called.

Returns:

the name of this function, as an IExpressionNode

resolveCalledExpression

IDefinition resolveCalledExpression(ICompilerProject project)

Resolves the expression being called to a definition.

The result may or may not be an IFunctionDefinition.

For example, in f(), f might be a variable of type Function, and so this function would return an IVariableDefinition.

As another example, in new Sprite(), Sprite resolves to a class, not to the constructor for that class, and so this function would return an IClassDefinition.

Parameters:

project - The ICompilerProject to use for lookups.

Returns:

An IDefinition or null.

getFunctionName

String getFunctionName()

The name of the function being called

Returns:

the name of this function

getArgumentNodes

IExpressionNode[] getArgumentNodes()

Returns an array of IExpressionNode nodes that are passed in as parameters to this function call

Returns:

an array of IExpressionNodes or an empty array

isNewExpression

boolean isNewExpression()

Returns true if this function call is part of a new expression new String();

Returns:

true if this is a new expression

isSuperExpression

boolean isSuperExpression()

Returns true if this function call is part of a super expression super();

Returns:

true if this name node is a super expression

isCallToSuper

boolean isCallToSuper()

Returns true if this function call is a call to a super expression foo.super();

Returns:

true if this name node calls a super expression

getArgumentsNode

ContainerNode getArgumentsNode()

Get the arguments being passed

Returns:

node containing the arguments being passed to the function

getNewKeywordNode

KeywordNode getNewKeywordNode()

Get the new keyword, if one is present

Returns:

node containing the new keyword
