com.tangosol.coherence.servlet
Class AbstractHttpSessionCollection.DistributedController

java.lang.Object
com.tangosol.coherence.servlet.AbstractHttpSessionCollection.DistributedController

All Implemented Interfaces:

HttpSessionCollection.SessionDistributionController

Enclosing class:

AbstractHttpSessionCollection

Deprecated. In releases following 3.6 customization will be declarative.

public static class AbstractHttpSessionCollection.DistributedController

extends Object

implements HttpSessionCollection.SessionDistributionController

A simple implementation of the SessionDistributionController interface that forces all sessions (and thus their attributes) to be managed in a distributed manner. (This is the default behavior, but by having an implementation that forces this, the raw overhead of using a HttpSessionController can be measured.)

Since:

Coherence 2.4

Constructor Summary

AbstractHttpSessionCollection.DistributedController()
Deprecated.

Method Summary

void	init(HttpSessionCollection collection) Deprecated. Initialize the session distribution controller, so that it has the necessary context with which to make decisions regarding when to distribute sessions and their attributes.
boolean	isSessionAttributeDistributed(HttpSessionModel model, String sName) Deprecated. Determine if the specified attribute of the HttpSession associated with the passed session model should be distributed.
boolean	isSessionDistributed(HttpSessionModel model) Deprecated. Determine if the HttpSession associated with the passed session model should be distributed.

Method Detail

init

public void init(HttpSessionCollection collection)

Deprecated.

Initialize the session distribution controller, so that it has the necessary context with which to make decisions regarding when to distribute sessions and their attributes.

Specified by:

init in interface HttpSessionCollection.SessionDistributionController

Parameters:

collection - the HttpSessionCollection object for which the distribution controller is working

isSessionDistributed

public boolean isSessionDistributed(HttpSessionModel model)

Deprecated.

Determine if the HttpSession associated with the passed session model should be distributed. This method will only be called for sessions that are not already distributed.

Specified by:

isSessionDistributed in interface HttpSessionCollection.SessionDistributionController

Parameters:

model - the model for the HttpSession to evaluate for distribution

Returns:

true if the passed session model should be distributed

isSessionAttributeDistributed

public boolean isSessionAttributeDistributed(HttpSessionModel model,
                                             String sName)

Deprecated.

Determine if the specified attribute of the HttpSession associated with the passed session model should be distributed. This method will only be called for sessions that are distributed, and only for attributes that are not already distributed. Further, it may only be called when an attribute is added or when its value is modified. The value itself is not passed for performance reasons; if necessary, the implementation can obtain the value from the model, but it is suggested that the implementation use the name to make the determination if possible, and only failing that obtain and evaluate the attribute value.

Specified by:

isSessionAttributeDistributed in interface HttpSessionCollection.SessionDistributionController

Parameters:

model - the model for the HttpSession being evaluated

sName - the name of the session attribute to evaluate for distribution

Returns:

true if the specified attribute for the passed session model should be distributed
