Method Detail

getNodeType

public NodeType getNodeType()

Specified by:

getNodeType in class Node

Returns:

the nodeId

accept

public <T> T accept(NodeVisitor<T> iVisitor)

Accept for the visitor pattern.

Specified by:

accept in class Node

Parameters:

iVisitor - the visitor

getName

public RubySymbol getName()

Gets the name (this is the rightmost element of lhs (in Foo::BAR it is BAR). name is the constant Name, it normally starts with a Capital

Specified by:

getName in interface INameNode

Returns:

name

getConstNode

public Node getConstNode()

Get the full path, including the name of the new constant (in Foo::BAR it is Foo::BAR) or null. Your probably want to extract the left part with ((Colon2Node) node.getConstNode()).getLeftNode() if node.getConstNode() is a Colon2ConstNode.

Returns:

pathNode

childNodes

public java.util.List<Node> childNodes()

Specified by:

childNodes in class Node

needsDefinitionCheck

public boolean needsDefinitionCheck()

Description copied from class: Node

Check whether the given node is considered always "defined" or whether it has some form of definition check.

Overrides:

needsDefinitionCheck in class Node

Returns:

Whether the type of node represents a possibly undefined construct
