Introduction

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

Prototype

public static void isTrue(boolean expression) 

Source Link

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 ); Validate.isTrue( myObject.isOk() ); 

The message in the exception is 'The validated expression is false'.
