List of usage examples for org.apache.commons.lang Validate isTrue
public static void isTrue(boolean expression)
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'.
