Binary

Binary predicates for path patterns are boolean methods that takes two Nodes as arguments. The method is tested against the two nodes left and right in the query when used as predicate.

Example

module Organ(int age);
boolean t(Organ a, Organ b){
	return a[age] < b[age];
}
 
public void run ()
[
	o:isAge(5) -t-> i:Node ::>;
]
