public class WrapperRMIObjectWriteHandler implements RMIObjectWriteHandler
Writes the object using the given RMIWrapper passed in the constructor.

An RMIWrapper will be instantiated to transfer the given object over RMI. For more information see RMIWrapper.

In order to use this class with RMIWriter, subclass it, provide a no-arg default constructor which sets the appropriate RMIWrapper class, and use it as a value for the annotation.

Or use RMIWrap annotation without any subclassing.

Fields
protected final Class<extends RMIWrapper>
The wrapper class which is used to transfer objects.
Constructors
public
Creates a new instance with the given wrapper class.
Methods
public final boolean
Indicates whether some other object is "equal to" this one.
public final ObjectWriterKind
Gets the kind of this object write handler.
public final Class<extends RMIWrapper>
Gets the wrapper class that should be used to transfer objects.
public final int
Returns a hash code value for the object.
public String
Returns a string representation of the object.
Inherited methods
From: Object
protected final Class<extends RMIWrapper> wrapperClass
The wrapper class which is used to transfer objects.
Creates a new instance with the given wrapper class.
wrapperClassThe wrapper class.
NullPointerExceptionIf the argument is null.
IllegalArgumentExceptionIf the wrapper class is not a valid wrapper class. (If it is abstract, or enum.)
public final boolean equals(Object obj)
Overridden from: Object
Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

objthe reference object with which to compare.
true if this object is the same as the obj argument; false otherwise.
public final ObjectWriterKind getKind()
Overridden from: RMIObjectWriteHandler
Gets the kind of this object write handler.
The kind.
public final Class<extends RMIWrapper> getWrapperClass()
Gets the wrapper class that should be used to transfer objects.
The wrapper class.
public final int hashCode()
Overridden from: Object
Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the Object.equals(Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)

a hash code value for this object.
public String toString()
Overridden from: Object
Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
 
a string representation of the object.
