Method Detail

getBytes

public byte[] getBytes()

Gets the ServiceDataElement, represented as a byte array

getObject

public java.lang.Object getObject(byte[] bytes)

Converts the given byte array into an object of the appropriate type

setValue

public void setValue(byte[] bytes)

Sets a new value for the SDE from the given byte array.

getValue

public java.lang.Object getValue()

Gets the value of the ServiceDataElement

setValue

public void setValue(java.lang.Object newValue)

Sets the ServiceDataElement to a new value and notifies the StyxFile interfaces to this SDE

getName

public java.lang.String getName()

Gets the name of this SDE

isReadOnly

public boolean isReadOnly()

Returns:

true if this SDE is read-only

getStyxFile

public StyxFile getStyxFile()
                     throws StyxException

Gets the StyxFile that provides non-blocking access to this SDE

Throws:

StyxException

getAsyncStyxFile

public StyxFile getAsyncStyxFile()
                          throws StyxException

Gets the StyxFile that provides asynchronous access to this SDE

Throws:

StyxException

flush

public void flush()

Forces all waiting clients to get an update on this quantity, irrespective of how long they have waited since the last update. Does nothing if the AsyncStyxFile has not been created (there will be no clients waiting).
