Method Detail

register

public void register(java.lang.String name,
                     Registry registry)
              throws PropertyException
Description copied from interface: Configurable
Register my properties. This method is called once early in the time of the component, shortly after the component is constructed. This component should register any configuration properties that it needs to register. If this configurable extends another configurable, super.register should also be called

Specified by:
register in interface Configurable
Parameters:
name - the name of the component
registry - the registry for this component
Throws:
PropertyException

newProperties

public void newProperties(PropertySheet ps)
                   throws PropertyException
Description copied from interface: Configurable
This method is called when this configurable component has new data. The component should first validate the data. If it is bad the component should return false. If the data is good, the component should record the the data internally and return true.

Specified by:
newProperties in interface Configurable
Parameters:
ps - a property sheet holding the new data
Throws:
PropertyException - if there is a problem with the properties.

getName

public java.lang.String getName()
Description copied from interface: Configurable
Retrieves the name for this configurable component

Specified by:
getName in interface Configurable
Returns:
the name

statusChanged

public void statusChanged(RecognizerState status)
Description copied from interface: StateListener
Called when the status has changed.

Specified by:
statusChanged in interface StateListener
Parameters:
