///**
|
||||
// * Assertion utility class that assists in validating arguments.
|
||||
// *
|
||||
// * <p>Useful for identifying programmer errors early and clearly at runtime.
|
||||
// *
|
||||
// * <p>For example, if the contract of a public method states it does not
|
||||
// * allow {@code null} arguments, {@code Assert} can be used to validate that
|
||||
// * contract. Doing this clearly indicates a contract violation when it
|
||||
// * occurs and protects the class's invariants.
|
||||
// *
|
||||
// * <p>Typically used to validate method arguments rather than configuration
|
||||
// * properties, to check for cases that are usually programmer errors rather
|
||||
// * than configuration errors. In contrast to configuration initialization
|
||||
// * code, there is usually no point in falling back to defaults in such methods.
|
||||
// *
|
||||
// * <p>This class is similar to JUnit's assertion library. If an argument value is
|
||||
// * deemed invalid, an {@link IllegalArgumentException} is thrown (typically).
|
||||
// * For example:
|
||||
// *
|
||||
// * <pre class="code">
|
||||
// * Assert.notNull(clazz, "The class must not be null");
|
||||
// * Assert.isTrue(i > 0, "The value must be greater than zero");</pre>
|
||||
// *
|
||||
// * <p>Mainly for internal use within the framework; consider
|
||||
// * <a href="http://commons.apache.org/proper/commons-lang/">Apache's Commons Lang</a>
|
||||
// * for a more comprehensive suite of {@code String} utilities.
