UnixNumericUserPrincipal

public class UnixNumericUserPrincipal extends Object implements Principal, Serializable

This class implements the Principal interface and represents a user's Unix identification number (UID).

Principals such as this UnixNumericUserPrincipal may be associated with a particular Subject to augment that Subject with an additional identity. Refer to the Subject class for more information on how to achieve this. Authorization decisions can then be based upon the Principals associated with a Subject.

param
o Object to be compared for equality with this UnixNumericUserPrincipal.
return
true if the specified Object is equal equal to this UnixNumericUserPrincipal.

return
the user identification number (UID) for this UnixNumericUserPrincipal

	return name;
public inthashCode()
Return a hash code for this UnixNumericUserPrincipal.

return
a hash code for this UnixNumericUserPrincipal.

	return name.hashCode();
public longlongValue()
Return the user identification number (UID) for this UnixNumericUserPrincipal as a long.

return
the user identification number (UID) for this UnixNumericUserPrincipal as a long.
