DefaultIdentifiable(Integer id)
Creates a new Identifiable object.

Method Summary

int	compareTo(DefaultIdentifiable o) Compares this object with the specified object for order.
boolean	equals(Object o) Indicates whether some other object is "equal to" this one.
Integer	getID() Returns the unique id of this object.
int	hashCode() Returns a hash code value for the object.

Constructor Detail

DefaultIdentifiable

public DefaultIdentifiable()

Empty constructor for serialization purposes.

DefaultIdentifiable

public DefaultIdentifiable(Integer id)

Creates a new Identifiable object.

Parameters:

id - the unique id of this Identifiable

Method Detail

getID

public Integer getID()

Returns the unique id of this object.

Specified by:

getID in interface Identifiable

Returns:

the unique id of this object

compareTo

public int compareTo(DefaultIdentifiable o)

Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

Specified by:

compareTo in interface Comparable<DefaultIdentifiable>

Parameters:

o - the Object to be compared.

Returns:

a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

toString

public String toString()

Returns a string representation of the object.

Overrides:

toString in class Object

Returns:

a string representation of the object.

equals

public boolean equals(Object o)

Indicates whether some other object is "equal to" this one.

Overrides:

equals in class Object

Parameters:

o - the reference object with which to compare.

hashCode

public int hashCode()

Returns a hash code value for the object.

Overrides:

hashCode in class Object

Returns:

a hash code value for the object

writeExternal

public void writeExternal(ObjectOutput out)
                   throws IOException

The object implements the writeExternal method to save its contents by calling the methods of DataOutput for its primitive values or calling the writeObject method of ObjectOutput for objects, strings, and arrays.

Specified by:

writeExternal in interface Externalizable

Parameters:

out - the stream to write the object to

Throws:

IOException - on write errors

readExternal

public void readExternal(ObjectInput in)
                  throws IOException

The object implements the readExternal method to restore its contents by calling the methods of DataInput for primitive types and readObject for objects, strings and arrays. The readExternal method must read the values in the same sequence and with the same types as were written by writeExternal.

Specified by:

readExternal in interface Externalizable

Parameters:

in - the stream to read data from in order to restore the object

Throws:

IOException - on read errors
