方法详细资料

getNotNullObject

public static <T> T getNotNullObject(Class<T> c,
                     T t)

Description：
如前传入的对象t为null，则通过返映实例货传入的类型实例

参数:

c -

t -

返回:

T

equals

public static boolean equals(Object obj1,
             Object obj2)

Safely compares two objects just like equals() would, except it allows any of the 2 objects to be null.

返回:

true if arguments are equal, otherwise false

equalsEx

public static boolean equalsEx(Object obj1,
               Object obj2)

Compares two objects or two object arrays. Useful for Object.equals(Object).

另请参阅:

equals(Object, Object)

equalsType

public static boolean equalsType(Object object,
                 Object thiz)

Non-symmetric utility for comparing the types of two objects. Might be useful for Object.equals(Object) if instanceof is not used.

参数:

object - equals() argument

thiz - current class that overrides equals()

clone

public static Object clone(Object source)
                    throws CloneNotSupportedException

Clone an object by invoking it's clone() method, even if it is not overridden.

抛出:

CloneNotSupportedException

length

public static int length(Object obj)

Returns length of the object.

containsElement

public static boolean containsElement(Object obj,
                      Object element)

Returns true if first argument contains provided element. s
