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

getBodyNode

public Node getBodyNode()

Gets the body of this class.

Specified by:

getBodyNode in interface IScopingNode

Returns:

the contents

getEndLine

public int getEndLine()

Gets line where the 'end' was for this module.

getScope

public StaticScope getScope()

Get the static scoping information.

Specified by:

getScope in interface IScopingNode

Returns:

the scoping info

getCPath

public Colon3Node getCPath()

Gets the className.

Specified by:

getCPath in interface IScopingNode

Returns:

Returns representation of class path+name

getSuperNode

public Node getSuperNode()

Gets the superNode.

Returns:

Returns a Node

childNodes

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

Specified by:

childNodes in class Node

executesOnce

public boolean executesOnce()

Overrides:

executesOnce in class Node

Returns:

is it possible this node will execute only once. Note: This is not comprehensive. It is used to look from root node down to class/module nodes to make sure that narrow case can execute once. It is possible much deeper down the tree some nodes can only execute once but it will be marked as false because that case is not what this is for.
