NAME

afnix-us-csm - standard collection session management service

STANDARD CONTENT SESSION MANAGEMENT SERVICE

The Standard Content Session Management service is an original implementation of various objects dedicated to the management of sessions, realms, identities and more generaly with data concentration in the form of binary blobs.

General concepts
The afnix-csm provides the support for manipulating content session in an ecclectic form. There are multiple types of objects which can broadly be categorized into general data management in the form of data blobs, identity and credential management and finally session management.

Blob
The concept of blob is central in the csm service. A blob is a registrable part. A part is an abstract taggable object uniquely identified by a uuid. The blob adds a registration identification, which enables them to be group into domains.

STANDARD CONTENT SESSION MANAGEMENT REFERENCE

Part
The Part class is a taggable object which is bound by a unique key and provide a plist interface access. The part object is the foundation of the blob object and is also used to feed a collection. The key is represented by a uuid object.

Predicate

part-p

Inheritance

Taggable

Constructors

Part (none)
The Part constructor creates an empty part

Part (String)
The Part constructor creates a part by name.

Part (String String)
The Part constructor creates a part by name and info strings.

Methods

kid-p -> Boolean (String)
The kip-p predicate returns true if the part kid can be validated.

property-p -> Boolean (String)
The property-p predicate returns true if the property name argument is defined in the part.

get-kid -> Uuid (none)
The get-kid method returns the part kid.

add -> none (String Literal)

get-header -> Plist (none)
The get-header method returns the part header which is a plist with the part name, info and uuid.

get-plist -> Plist (none)
The get-plist method returns the part plist.

get-value -> String (String)
The get-value method returns the a part property value by name.

to-lteral -> Literal (String)
The toliteral method returns the a part property literal by name.

Blob
The Blob class is a base class that models the behavior of a registered blob through the use of a registration id. The blob is registered as soon as its registration id is set. If the registration id is unset, the object is unregistered or anonymous. The registration id can be anything as long as as it is understood by the implementation that such registration is to be interpreted somewhere else. The blob is also a part which means that it has a name, info and unique key.

Carrier
The Carrier class is a blob used to transport an object. The object transported by the carrier must be serializable.

Methods

get-object -> Object (none)

Delegate
The Delegate class is a carrier blob which delegates its transport to another object. Such approach is used when the carried object needs to remains locally (aka it cannot be serialized) but a reference to it can be sent to the remote peer.

Methods

set-address -> none (String)
The set-address method sets the delegate address.

get-address -> String (none)
The get-address method returns the delegate address.

Realm
The Realm class is an abstract class design for the storage and management of authorities. The class provides the basic methods to create, check and validate an authority.

Predicate

realm-p

Inheritance

Nameable

Methods

exists-p -> Boolean (String)
The exists-p predicate checks if an authority exists by kid.

valid-p -> Boolean (String Credential)

create -> none (String Credential)
The create method creates an authority by name and credential.

update -> none (Authority)
The update method updates a workzone by authority.

Session
The Session class is a class that defines a session to be associated with a transaction. The session object is designed to be persistent so that its data information can be retreived at any time. A session object has also the particularity to have a limited lifetime. A session object is created by name with an identifier. The session object is designed to hold a variety of parameters that are suitable for both the authentication and the session lifetime. A session is primarily defined by name with an optional information string. The session is generally associated an authentication visa which contains the session identity. The visa provides a secure mechanism compatible with a single sign on session. A session key is automatically generated when the session is created. Such key is used to generate a session hash id which can be used as a cookie value. The cookie name is also stored in the session object. When a cookie is generated, the session hash name is combined with the session hash id for the cookie production.

Predicate

Constructors

Session (String)
The Session constructor creates a session by name. The string argument is the session name.
