Class IntPredicateLambda

java.lang.Object

net.sf.saxon.z.IntPredicateLambda

All Implemented Interfaces:

IntPredicate, IntPredicateProxy

public class IntPredicateLambda
extends Object
implements IntPredicateProxy

This class allows an integer predicate (a boolean function of an integer) to be written as a lambda expression, in a way that works both in Java and C#. It is needed because interfaces and delegates are interchangeable in Java (through the mechanism of "functional interfaces"), but the same is not the case in C#.

Implement an integer predicate as a lambda expression

Parameters:

lambda - an implementation of the functional interface IntPredicate, generally supplied as a lambda expression (for example i -> i > 0 for a predicate that matches all positive integers).

Returns:

the integer predicate
