equals in interface AclObjectIdentity

Overrides:

equals in class java.lang.Object

Parameters:

arg0 - object to compare

Returns:

true if the presented object matches this object

getClassname

public java.lang.String getClassname()

Indicates the classname portion of the object identity.

Returns:

the classname (never null)

getId

public java.lang.String getId()

Indicates the instance identity portion of the object identity.

the instance identity (never null)

hashCode

public int hashCode()

Important so caching operates properly.

Specified by:

hashCode in interface AclObjectIdentity

Overrides:

hashCode in class java.lang.Object

Returns:

the hash of the classname and id

toString
