Introduction

In this page you can find the example usage for org.apache.commons.lang3.tuple Pair of.

Document

Obtains an immutable pair of from two objects inferring the generic types.

This factory allows the pair to be created using inference to obtain the generic types.

Usage

From source file:com.tussle.motion.CollisionMap.java

public ProjectionVector get(StageElement<CollisionStadium> c, StageElement s) {
    //Ah well, looks like I'm going to have to use a transient pair
    return get(Pair.of(c, s));
}
