Known Indirect Subclasses

Group, GroupImpl, HttpPrincipal, Identity, IdentityDatabase, IdentityScope, JMXPrincipal, KerberosPrincipal, LdapPrincipal, NTDomainPrincipal, NTSid, NTSidDomainPrincipal, NTSidGroupPrincipal, NTSidPrimaryGroupPrincipal, NTSidUserPrincipal, and 16 others.

Group	This interface is used to represent a group of principals.
GroupImpl	This class implements a group of principals.
HttpPrincipal	Represents a user authenticated by HTTP Basic or Digest authentication.
Identity	This class is deprecated. This class is no longer used. Its functionality has been replaced by `java.security.KeyStore`, the `java.security.cert` package, and `java.security.Principal`.
IdentityDatabase	An implementation of IdentityScope as a persistent identity database.
IdentityScope	This class is deprecated. This class is no longer used. Its functionality has been replaced by `java.security.KeyStore`, the `java.security.cert` package, and `java.security.Principal`.
JMXPrincipal	The identity of a remote client of the JMX Remote API.
KerberosPrincipal	This class encapsulates a Kerberos principal.
LdapPrincipal	A principal identified by a distinguished name as specified by RFC 2253.
NTDomainPrincipal	This class implements the `Principal` interface and represents the name of the Windows NT domain into which the user authenticated.
NTSid	This class implements the `Principal` interface and represents information about a Windows NT user, group or realm.
NTSidDomainPrincipal	This class extends `NTSid` and represents a Windows NT user's domain SID.
NTSidGroupPrincipal	This class extends `NTSid` and represents one of the groups to which a Windows NT user belongs.
NTSidPrimaryGroupPrincipal	This class extends `NTSid` and represents a Windows NT user's primary group SID.
NTSidUserPrincipal	This class extends `NTSid` and represents a Windows NT user's SID.
NTUserPrincipal	This class implements the `Principal` interface and represents a Windows NT user.
PrincipalImpl	This class implements the principal interface.
Signer	This class is deprecated. This class is no longer used. Its functionality has been replaced by `java.security.KeyStore`, the `java.security.cert` package, and `java.security.Principal`.
SolarisNumericGroupPrincipal	This class is deprecated. As of JDK 1.4, replaced by `UnixNumericGroupPrincipal`. This class is entirely deprecated.
SolarisNumericUserPrincipal	This class is deprecated. As of JDK 1.4, replaced by `UnixNumericUserPrincipal`. This class is entirely deprecated.
SolarisPrincipal	This class is deprecated. As of JDK 1.4, replaced by `UnixPrincipal`. This class is entirely deprecated.
SystemIdentity	An identity with a very simple trust mechanism.
SystemSigner	SunSecurity signer.
UnixNumericGroupPrincipal	This class implements the `Principal` interface and represents a user's Unix group identification number (GID).
UnixNumericUserPrincipal	This class implements the `Principal` interface and represents a user's Unix identification number (UID).
UnixPrincipal	This class implements the `Principal` interface and represents a Unix user.
UserPrincipal	A user principal identified by a username or account name.
WorldGroupImpl	This class implements a group of principals.
X500Name	Note: As of 1.4, the public class, javax.security.auth.x500.X500Principal, should be used when parsing, generating, and comparing X.500 DNs.
X500Principal	This class is deprecated. A new X500Principal class is available in the Java platform. This X500Principal classs is entirely deprecated and is here to allow for a smooth transition to the new class.
X500Signer	This class provides a binding between a Signature object and an authenticated X.500 name (from an X.509 certificate chain), which is needed in many public key signing applications.

Class Overview

This interface represents the abstract notion of a principal, which can be used to represent any entity, such as an individual, a corporation, and a login id.

Summary

Public Methods
abstract boolean	equals(Object another) Compares this principal to the specified object.
abstract String	getName() Returns the name of this principal.
abstract int	hashCode() Returns a hashcode for this principal.
abstract String	toString() Returns a string representation of this principal.

Public Methods

public abstract boolean equals (Object another)

Compares this principal to the specified object. Returns true if the object passed in matches the principal represented by the implementation of this interface.

Parameters

another	principal to compare with.

Returns

true if the principal passed in is the same as that encapsulated by this principal, and false otherwise.

public abstract String getName ()

Returns the name of this principal.

Returns

the name of this principal.

public abstract int hashCode ()

Returns a hashcode for this principal.

Returns

a hashcode for this principal.

public abstract String toString ()

Returns a string representation of this principal.

Returns

a string representation of this principal.
