HTTPInstrumentManagerConnection

public HTTPInstrumentManagerConnection(java.net.URL url)

Creates a new HTTPInstrumentManagerConnection.

Method Detail

enableLogging

public void enableLogging(Logger logger)

Description copied from interface: LogEnabled

Provide component with a logger.

Specified by:

enableLogging in interface LogEnabled

Overrides:

enableLogging in class InstrumentManagerConnection

getKey

public java.lang.Object getKey()

Returns the key used to identify this object.

Specified by:

getKey in class InstrumentManagerConnection

Returns:

The key used to identify this object.

isConnected

public boolean isConnected()

Returns true if connected.

Specified by:

isConnected in class InstrumentManagerConnection

Returns:

True if connected.

getInstrumentManager

public InstrumentManagerData getInstrumentManager()

Returns the Instrument Manager.

Specified by:

getInstrumentManager in class InstrumentManagerConnection

Returns:

The Instrument Manager.

getTabTitle

public java.lang.String getTabTitle()

Returns the title to display in the tab for the connection.

Overrides:

getTabTitle in class InstrumentManagerConnection

Returns:

The tab title.

invokeGC

protected void invokeGC()

Invokes GC on the JVM running the InstrumentManager.

Specified by:

invokeGC in class InstrumentManagerConnection

saveState

public Configuration saveState()

Saves the current state into a Configuration.

Overrides:

saveState in class InstrumentManagerConnection

Returns:

The state as a Configuration.

loadState

public void loadState(Configuration state)
               throws ConfigurationException

Loads the state from a Configuration object.

Overrides:

loadState in class InstrumentManagerConnection

Parameters:

state - Configuration object to load state from.

Throws:

ConfigurationException - If there were any problems loading the state.

updateSampleFrames

public void updateSampleFrames()

Updates all registered SampleFrames with the latest data from the server. The status of all Sample Frames is also handled by this method, so it must handle disconnected connections and missing or expired samples correctly. This method overrides the default to implement a batch update to get all snapshots from the server in a single request.

Overrides:

updateSampleFrames in class InstrumentManagerConnection
