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

Implements abstract org.jruby.ast.Node.accept.

Accept for the visitor pattern.

Parameters
iVisitor:NodeVisitor<T>

the visitor

childNodesback to summary
public List<Node> childNodes()

executesOnceback to summary
public boolean executesOnce()

Overrides org.jruby.ast.Node.executesOnce.

Returns:boolean

Doc from org.jruby.ast.Node.executesOnce.

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.
