Method Detail

getNodeType

public NodeType getNodeType()

Overrides:

getNodeType in class ListNode

Returns:

the nodeId

accept

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

RubyMethod used by visitors. accepts the visitor

Overrides:

accept in class ListNode

Parameters:

iVisitor - the visitor to accept

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.
