Constructor Detail

FunctionCallNode

public FunctionCallNode(IASToken keywordNew,
                ExpressionNodeBase nameNode)

Constructor.

FunctionCallNode

public FunctionCallNode(ExpressionNodeBase nameNode)

Constructor.

FunctionCallNode

protected FunctionCallNode(FunctionCallNode 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

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

replaceChild

protected void replaceChild(NodeBase child,
                NodeBase target)

Description copied from class: NodeBase

Replaces the child with the given target. The child will be removed from the tree, and its parentage will be updated

Overrides:

replaceChild in class NodeBase

Parameters:

child - the NodeBase to replace

target - the NodeBase to replace the replaced

buildInnerString

protected boolean buildInnerString(StringBuilder sb)

Description copied from class: NodeBase

For debugging only. This method is called by buildOuterString(). It is overridden by subclasses to display optional node-specific information in the middle of the string, between the node type and the location information.

Overrides:

buildInnerString 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 FunctionCallNode 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

isNewExpression

public boolean isNewExpression()

Description copied from interface: IFunctionCallNode

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

Specified by:

isNewExpression in interface IFunctionCallNode

Returns:

true if this is a new expression

getNameNode

public ExpressionNodeBase getNameNode()

Description copied from interface: IFunctionCallNode

The expression being called.

Specified by:

getNameNode in interface IFunctionCallNode

Returns:

the name of this function, as an IExpressionNode

getFunctionName

public String getFunctionName()

Description copied from interface: IFunctionCallNode

The name of the function being called

Specified by:

getFunctionName in interface IFunctionCallNode

Returns:

the name of this function

resolveCalledExpression

public IDefinition resolveCalledExpression(ICompilerProject project)

Description copied from interface: IFunctionCallNode

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.

Specified by:

resolveCalledExpression in interface IFunctionCallNode

Parameters:

project - The ICompilerProject to use for lookups.

Returns:

An IDefinition or null.

getArgumentNodes

public IExpressionNode[] getArgumentNodes()

Description copied from interface: IFunctionCallNode

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

Specified by:

getArgumentNodes in interface IFunctionCallNode

Returns:

an array of IExpressionNodes or an empty array

isSuperExpression

public boolean isSuperExpression()

Description copied from interface: IFunctionCallNode

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

Specified by:

isSuperExpression in interface IFunctionCallNode

Returns:

true if this name node is a super expression

getArgumentsNode

public ContainerNode getArgumentsNode()

Description copied from interface: IFunctionCallNode

Get the arguments being passed

Specified by:

getArgumentsNode in interface IFunctionCallNode

Returns:

node containing the arguments being passed to the function

getNewKeywordNode

public KeywordNode getNewKeywordNode()

Description copied from interface: IFunctionCallNode

Get the new keyword, if one is present

Specified by:

getNewKeywordNode in interface IFunctionCallNode

Returns:

node containing the new keyword

setNewKeywordNode

public void setNewKeywordNode(KeywordNode newNode)

isCallToSuper

public boolean isCallToSuper()

Description copied from interface: IFunctionCallNode

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

Specified by:

isCallToSuper in interface IFunctionCallNode

Returns:

true if this name node calls a super expression
