Modifier and Type	Method and Description
static boolean	hasEquivalentFields(Object obj1, Object obj2) Given two object instances of the same type, this method accesses all their internal fields, including the fields of StateContainer if the class type is Component, to check if they are equivalent.
static boolean	isEquivalentToIgnoringState(Component current, Component next) Given two components this method accesses all their internal fields, excluding the fields of StateContainer if the class type is a Component, to check if they are equivalent.

Method Detail

isSameComponentType

public static boolean isSameComponentType(Component a,
                                          Component b)

isEquivalentToIgnoringState

public static boolean isEquivalentToIgnoringState(Component current,
                                                  Component next)

Given two components this method accesses all their internal fields, excluding the fields of StateContainer if the class type is a Component, to check if they are equivalent. There's special equality code to handle special class types e.g. Components, EventHandlers, etc.

Parameters:

current - current Component

next - next Component

Returns:

true iff the component fields are equivalent.

hasEquivalentFields

public static boolean hasEquivalentFields(Object obj1,
                                          Object obj2)

Given two object instances of the same type, this method accesses all their internal fields, including the fields of StateContainer if the class type is Component, to check if they are equivalent. There's special equality code to handle special class types e.g. Components, EventHandlers, etc.

Parameters:

obj1 -

obj2 -

Returns:

true if the two instances are equivalent. False otherwise.
