Examples of org.jnode.shell.syntax.PowersetSyntax

org.jnode.shell.syntax.PowersetSyntax
A Powerset syntax allows a group of child Syntaxes to be provided in any order. The syntax allows a child syntax to appear more than once, subject to Argument multiplicity constraints. As with an Alternatives, the child syntaxes are tried one at a time in the same order as the they were provided to the constructor. The 'eager' parameter specifies whether the syntax is 'eager' (i.e. matching as many instances as possible) or 'lazy' (i.e. matching as few instances as possible). @author crawley@jnode.org
