equals in interface ID

Specified by:

equals in interface Principal

Overrides:

equals in class Object

getName

public String getName()

Description copied from interface: ID

Get the unique name of this identity.

Specified by:

getName in interface ID

Specified by:

getName in interface Principal

Returns:

String unique name for this identity. Will not be null, and must be a unique String within the Namespace returned by getNamespace()

getNamespace

public Namespace getNamespace()

Description copied from interface: ID

Get the Namespace instance associated with this identity

Specified by:

getNamespace in interface ID

Returns:

Namespace the Namespace corresponding to this identity. Will not return null.

hashCode

hashCode in class Object

toExternalForm

public String toExternalForm()

Description copied from interface: ID

Get this ID instance in String form. Will not return null.

Specified by:

toExternalForm in interface ID

Returns:

String that is external representation of this ID

namespaceCompareTo

protected abstract int namespaceCompareTo(BaseID o)

Called by Namespace.getCompareToForObject(BaseID, BaseID).

Parameters:

o - the other ID to compare to. Will not be null.

Returns:

the appropriate value as per Comparable contract.

namespaceEquals

protected abstract boolean namespaceEquals(BaseID o)

Called by Namespace.testIDEquals(BaseID, BaseID).

Parameters:

o - the other ID to test against. May be null.

Returns:

true if this ID is equal to the given ID. false otherwise.

namespaceGetName

protected abstract String namespaceGetName()

Called by Namespace.getNameForID(BaseID).

Returns:

String name for this ID. Must not be null. Value returned should be unique within this Namespace.

namespaceHashCode

protected abstract int namespaceHashCode()

Called by Namespace.getHashCodeForID(BaseID).

Returns:

int hashCode for this ID. Returned value must be unique within this process.

namespaceToExternalForm

protected String namespaceToExternalForm()

Called by Namespace.toExternalForm(BaseID).

Returns:
