Example usage for org.apache.commons.lang3.tuple Triple of

Introduction

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

Prototype

public static <L, M, R> Triple<L, M, R> of(final L left, final M middle, final R right)

Source Link

Document

Obtains an immutable triple of from three objects inferring the generic types.

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