Method Detail

hasState

public boolean hasState()

Description copied from interface: HasNumericState

Returns true if this component currently holds state. This allows the presence of state to depend on the component's configuration.

Specified by:

hasState in interface HasNumericState

Returns:

true if this component holds state

getInitialState

public void getInitialState(NumericState nstate)

getState

public void getState(DataBuffer data)

Description copied from interface: HasNumericState

Saves state information for this component by adding data to the supplied DataBuffer. Existing data in the buffer should not be disturbed.

Specified by:

getState in interface HasNumericState

Parameters:

data - buffer for storing the state values.

setState

public void setState(DataBuffer data)

Description copied from interface: HasNumericState

Restores the state for this component by reading from the supplied data buffer, starting at the current buffer offsets.

Specified by:

setState in interface HasNumericState

Parameters:

data - buffer containing the state information
