Example usage for org.apache.commons.lang Validate isTrue

Introduction

In this page you can find the example usage for org.apache.commons.lang Validate isTrue.

Prototype

public static void isTrue(boolean expression, String message)

Document

Validate an argument, throwing IllegalArgumentException if the test result is false.

This is used when validating according to an arbitrary boolean expression, such as validating a primitive number or using your own custom validation expression.

 Validate.isTrue( (i > 0), "The value must be greater than zero"); Validate.isTrue( myObject.isOk(), "The object is not OK");

For performance reasons, the message string should not involve a string append, instead use the #isTrue(boolean,String,Object) method.
