Java 8+ functional interfaces for primitive types

The newest version!

package com.github.tommyettinger.function;

/**
 * Represents an operation that accepts a single {@code int}-valued argument and
 * returns a {@code boolean} result.
 * 

 * This is identical to {@code IntPredicate} in Java 8, and is present here so environments
 * that support lambdas but not Java 8 APIs (such as RoboVM) can use it.
 * 

 * This is a functional interface whose functional method is {@link #test(int)}.

   * Evaluates this predicate on the given argument.
   *
   * @param value the input argument
   * @return {@code true} if the input argument matches the predicate,
   * otherwise {@code false}
