Method Detail

getModelName

public final java.lang.String getModelName()

Returns a name for identification

init

public void init()
          throws java.lang.Exception

Is called on model after the ServerContext has been constructed successfully. This default implementation just logs that the model has been initialized.

Specified by:

init in interface Initializable

Throws:

java.lang.Exception

setInitialized

protected final void setInitialized()

isInitialized

public final boolean isInitialized()

Description copied from interface: Initializable

Tells whether initialization has yet been done.

Specified by:

isInitialized in interface Initializable

checkInitialized

public final void checkInitialized()
                            throws NotInitializedException

Description copied from interface: Initializable

Checks whether initialization has yet been done and throws an NotInitializedException if not.

Specified by:

checkInitialized in interface Initializable

Throws:

NotInitializedException

close

public void close()

Is called on model when the ServerContext is closed. This default implementation just logs that the model has been destroyed.

Specified by:

close in interface java.lang.AutoCloseable

getCreatedTs

public final java.sql.Timestamp getCreatedTs()

getLastAccessedTs

public final java.sql.Timestamp getLastAccessedTs()

Description copied from interface: LastAccessed

Returns the timestamp of last client access

Specified by:

getLastAccessedTs in interface LastAccessed

getLastAccessorId

public final SessionId getLastAccessorId()

Description copied from interface: LastAccessed

Tells which client has last accessed the model

Specified by:

getLastAccessorId in interface LastAccessed

setLastAccessorId

public final void setLastAccessorId(SessionId sessId)

Description copied from interface: LastAccessed

Sets the sessionId of the client who has last accessed the model

Specified by:

setLastAccessorId in interface LastAccessed

sendChangeEvent

protected void sendChangeEvent(NetEvent event)

This method should be called for any change on the model in order to notify all clients. It also ensures the last accessor to be stored in the model.
