Class AssociationSessionType

java.lang.Object

org.openid4java.association.AssociationSessionType

All Implemented Interfaces:

Comparable

public class AssociationSessionType
extends Object
implements Comparable

Modells the session and association types allowed in OpenID associations.

Association requests and responses must have one of the AssociationSessionType's defined here.

Compatibility mode flag defines backwards-compatibile value sets allowed in OpenID 1.x, but not in OpenID 2

Method Detail

create

public static AssociationSessionType create(String sessType)
                                     throws AssociationException

Creates a OpenID 2 AssociationSessionType with the specified session type and HMAC-SHA1 association type.

Parameters:

sessType - The session type.

Throws:

AssociationException

create

public static AssociationSessionType create(String sessType,
                            String assocType)
                                     throws AssociationException

Creates a OpenID 2 AssociationSessionType with the specified session and association types.

Parameters:

sessType - The session type.

assocType - The association type.

Throws:

AssociationException

create

public static AssociationSessionType create(String sessType,
                            String assocType,
                            boolean compatibility)
                                     throws AssociationException

Creates a AssociationSessionType with the specified session and association types.

Compatibility flag defines backwards-compatibile value sets allowed in OpenID 1.x, but not in OpenID 2

Parameters:

sessType - The session type.

assocType - The association type.

compatibility - True for OpenID 1.x association / session types.

Throws:

AssociationException - For unsupported parameter sets.

getSessionType

public String getSessionType()

Gets the session type.

getHAlgorithm

public String getHAlgorithm()

Gets the H algorithm of the Diffie-Hellman session, or null for no-encryption session types.

getAssociationType

public String getAssociationType()

Gets the association type.

getKeySize

public int getKeySize()

Gets the MAC key size, in bits, of this association type.

compareTo

public int compareTo(Object object)

Compares to another AssociationSessionType; used for sorting.

Specified by:

compareTo in interface Comparable

isBetter

public boolean isBetter(AssociationSessionType other)

Returns true if the specified argument's encryption level is considered better than the one of the current instance.

isVersion2

public boolean isVersion2()

Returns true for OpenID 2 AssociationSessionType's, or false for OpenID 1.x types.

toString

public String toString()

Overrides:

toString in class Object
