id - The identifier value.

Method Detail

readExternal

public void readExternal(ObjectInput in)
                  throws IOException,
                         ClassNotFoundException

Specified by:

readExternal in interface Externalizable

Throws:

IOException

ClassNotFoundException

writeExternal

public void writeExternal(ObjectOutput out)
                   throws IOException

Specified by:

writeExternal in interface Externalizable

Throws:

IOException

getId

public String getId()

Returns the current identifier value.

Returns:

String

compareFreshness

public int compareFreshness(InstanceIdentifier instanceId)
                     throws ComparisonImpossibleException

The compareFreshness() method computes the "freshness distance" between the two objects (the one the method is applied on and the one provided in parameters). The return value is an integer representing this distance. A value of zero means that the objects are equals in terms of freshness. ComparisonImpossibleException will be thrown if the two objects can not be compared.

Specified by:

compareFreshness in interface InstanceIdentifier

Parameters:

instanceId -

Returns:

int

Throws:

ComparisonImpossibleException

toExternalForm

public String toExternalForm()

Return the external form of this Identifier.

Specified by:

toExternalForm in interface Identifier

Returns:

String

equals

public boolean equals(Object object)

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

Specified by:

equals in interface Identifier

Parameters:

object -

Returns:

boolean

hashCode

public int hashCode()

Returns a hash code value for the object.

Specified by:

hashCode in interface Identifier

Returns:

int

toString

public String toString()
