Class MonolithicHttpSessionModel

java.lang.Object
com.tangosol.util.Base
com.tangosol.coherence.servlet.AbstractHttpSessionModel
com.tangosol.coherence.servlet.MonolithicHttpSessionModel

All Implemented Interfaces:

HttpSessionModel, ExternalizableLite, Externalizable, Serializable

Deprecated. In releases following 3.6 customization will be declarative.

public class MonolithicHttpSessionModel

extends AbstractHttpSessionModel

This is an implementation of HttpSessionModel that manages its attribute state in a single ('monolithic') serializable unit, allowing session attributes to safely form graphs while avoiding duplication of objects, yet not being able to optimize attribute serialization and deserialization as a result.

Version:

Coherence 2.5

Constructor Detail

MonolithicHttpSessionModel

public MonolithicHttpSessionModel()

Deprecated.

Default constructor for deserialization.

MonolithicHttpSessionModel

public MonolithicHttpSessionModel(MonolithicHttpSessionCollection collection,
                                  javax.servlet.http.HttpSession session,
                                  String sId)

Deprecated.

Session creation constructor.

Parameters:

collection - the collection that manages this model

session - the session that delegates to this model

sId - the session ID

Method Detail

readAttributes

protected void readAttributes(DataInput in)
                       throws IOException

Deprecated.

Helper to read the session attributes from a stream.

Overrides:

readAttributes in class AbstractHttpSessionModel

Parameters:

in - the stream to read data from in order to restore the object

Throws:

IOException - if an I/O exception occurs

writeAttributes

protected void writeAttributes(DataOutput out)
                        throws IOException

Deprecated.

Helper to write the session attributes to a stream.

Overrides:

writeAttributes in class AbstractHttpSessionModel

Parameters:

out - the stream to write the object to

Throws:

IOException - if an I/O exception occurs

enterWriteAttributes

protected void enterWriteAttributes()

Deprecated.

Specify that the attributes are now being written.

leaveWriteAttributes

protected void leaveWriteAttributes()

Deprecated.

Specify that the attributes are no longer being written.

isWritingAttributes

protected boolean isWritingAttributes()

Deprecated.

Determine if the attributes are currently being written.

Returns:

true if the writeAttributes(java.io.DataOutput) processing is occurring

getAttributeSerializationFailureMap

protected Map getAttributeSerializationFailureMap()

Deprecated.

Get the map of attributes that cannot be written. This map should only exist during attribute serialization, and only if failures occur.

Returns:

a map of currently accumulating unserializable attributes, or null

setAttributeSerializationFailureMap

protected void setAttributeSerializationFailureMap(Map mapFailures)

Deprecated.

Set the map of attributes that cannot be written. This map should only exist during attribute serialization, and only if failures occur.

Parameters:

mapFailures - the map

ensureAttributeSerializationFailureMap

protected Map ensureAttributeSerializationFailureMap()

Deprecated.

Ensure that the map of attributes that cannot be written exists, creating it if necessary, and return it.

Returns:

a map of currently accumulating unserializable attributes; never null

logAttributeSerializationFailure

protected void logAttributeSerializationFailure(AbstractHttpSessionModel.AttributeHolder holder,
                                                Throwable e)

Deprecated.

Log a serialization failure for an attribute holder.

Overrides:

logAttributeSerializationFailure in class AbstractHttpSessionModel

Parameters:

holder - the attribute holder that failed to serialize its value

e - the throwable object that resulted from the serialization failure

toString

public String toString()

Deprecated.

Returns a string representation of the object.

Overrides:

toString in class AbstractHttpSessionModel

Returns:

a string representation of the object
