Method Summary

static boolean	areEqual(java.lang.Object o1, java.lang.Object o2) Returns true if the two objects are equal by reference or by .equals().
static void	clearEquatableClasses() Clears the list of classes marked as equatable.
static void	clearEquatableOverrides() Clears the list of instances marked as equatable.
static void	clearEquatables() Clears both classes and instances that have been marked as equatable.
static java.lang.Object	cloneObject(java.lang.Object obj) Clones the specified object if it is cloneable and has a public clone() method.
static java.util.List	deepCloneList(java.util.List list) Deep clones a list, iterating and cloning each list element
static boolean	isEquatable(java.lang.Class type) Returns true if the specified class or its hierarchy has its own .equals() method instead of inheriting one from Object.class.
static boolean	isEquatable(java.lang.Object obj) Returns true if the class of the specified object implements its own .equals() method.
static void	main(java.lang.String[] args)
static void	markEquatable(java.lang.Class type) Manually marks a class as equatable for future checks by the isEquatable method.
static void	markEquatable(java.lang.Object instance) Manually marks an instance as equatable for future checks by the isEquatable(Object) method.

Method Detail

cloneObject

public static java.lang.Object cloneObject(java.lang.Object obj)

Clones the specified object if it is cloneable and has a public clone() method. Returns the specified instance otherwise.

deepCloneList

public static java.util.List deepCloneList(java.util.List list)

Deep clones a list, iterating and cloning each list element

Parameters:

list -

Returns:

ArrayList

isEquatable

public static boolean isEquatable(java.lang.Object obj)

Returns true if the class of the specified object implements its own .equals() method.

isEquatable

public static boolean isEquatable(java.lang.Class type)

Returns true if the specified class or its hierarchy has its own .equals() method instead of inheriting one from Object.class.

markEquatable

public static void markEquatable(java.lang.Class type)

Manually marks a class as equatable for future checks by the isEquatable method.

markEquatable

public static void markEquatable(java.lang.Object instance)

Manually marks an instance as equatable for future checks by the isEquatable(Object) method.

clearEquatableClasses

public static void clearEquatableClasses()

Clears the list of classes marked as equatable. Primarilly intended for use in tests to reset the static equatable map in between tests.

clearEquatableOverrides

public static void clearEquatableOverrides()

Clears the list of instances marked as equatable. Primarilly intended for use in tests to reset the static overrides set in between tests.

clearEquatables

public static void clearEquatables()

Clears both classes and instances that have been marked as equatable. Primarilly intended for use in tests to reset the static equatable information in between tests.

areEqual

public static boolean areEqual(java.lang.Object o1,
                               java.lang.Object o2)

Returns true if the two objects are equal by reference or by .equals().

main

public static void main(java.lang.String[] args)
                 throws java.lang.Exception

Throws:

java.lang.Exception
