public final class ClassUtils
extends java.lang.Object

Provides utility methods to get information on Class objects.

Method Summary

static boolean	classEquals(java.lang.Class<?> class1, java.lang.Class<?> class2) This will test equality between two classes.
static boolean	hasMethod(java.lang.Class<?> clazz, java.lang.String methodName, java.lang.Class<?>... parameters) Iterates through a given Class public Methods to determine if it declares a method of the given name and parameters.
static java.lang.Object	invokeMethod(java.lang.Object object, java.lang.String methodName, java.lang.Object... parameters) Convenience method to reflectively invoke a given method on the given object with the given parameters.

Method Detail

classEquals

public static boolean classEquals(java.lang.Class<?> class1,
                                  java.lang.Class<?> class2)

This will test equality between two classes.

We'll assume that primitives types are equal to their wrappers so that parameterEquals(java.lang.Integer, int) returns True.

Parameters:

class1 - First of the two classes to test for equality.

class2 - Second of the two classes to test for equality.

Returns:

True if the two classes are considered equal, False otherwise.

hasMethod

public static boolean hasMethod(java.lang.Class<?> clazz,
                                java.lang.String methodName,
                                java.lang.Class<?>... parameters)

Iterates through a given Class public Methods to determine if it declares a method of the given name and parameters.

Parameters:

clazz - Class to visit.

methodName - Name of the method we search for.

parameters - Types of the researched method parameters.

Returns:

True if the given Class object declares a Method called methodName.

invokeMethod

public static java.lang.Object invokeMethod(java.lang.Object object,
                                            java.lang.String methodName,
                                            java.lang.Object... parameters)

Convenience method to reflectively invoke a given method on the given object with the given parameters. This implementation takes care of checking if the method exists beforehand and will return null if it does not.

Parameters:

object - Invocation target.

methodName - Name of the method to invoke.

parameters - Parameters with which to invoke the method.

Returns:

Result of the invocation or null if the method does not exist according to hasMethod(Class, String, Class...).
