public abstract class BaseID
extends java.lang.Object
implements ID

Base class for ID implementation classes Extensions for the org.eclipse.ecf.namespace extension point that expose new Namespace subclasses and their own ID implementations are recommended (but not required) to use this class as a superclass.

public int compareTo(java.lang.Object o)

Specified by:

compareTo in interface java.lang.Comparable

equals

public boolean equals(java.lang.Object o)

Specified by:

equals in interface java.security.Principal

Specified by:

equals in interface ID

Overrides:

equals in class java.lang.Object

getName

public java.lang.String getName()

Description copied from interface: ID

Get the unique name of this identity.

Specified by:

getName in interface java.security.Principal

Specified by:

getName in interface ID

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

public int hashCode()

Specified by:

hashCode in interface java.security.Principal

Specified by:

hashCode in interface ID

Overrides:

hashCode in class java.lang.Object

toExternalForm

public java.lang.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 java.lang.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 java.lang.String namespaceToExternalForm()

Called by Namespace.toExternalForm(BaseID).

Returns:
