Method Detail

get

public Parser.Node get(int index)

Description copied from class: Parser.Node

needs to be overridden when there are descendants.

Specified by:

get in interface List<Parser.Node>

Overrides:

get in class Parser.Node

Throws:

IndexOutOfBoundsException - if index is not less then size().

size

public int size()

Description copied from class: Parser.Node

needs to be overridden when there are descendants.

Specified by:

size in interface Collection<Parser.Node>

Specified by:

size in interface List<Parser.Node>

Overrides:

size in class Parser.Node

Returns:

nodes.length.

visit

public void visit(Visitor visitor)

Description copied from class: Parser.Node

implements divide and conquer for Visitor. Body must be visitor.visit(this);.

Specified by:

visit in class Parser.Node
