Enumeration DocumentIdConverterInterfaceSignal

The DocumentIdConverterInterfaceSignal lists all the signals that may be sent by the DocumentIdConverterInterface.

These signals are emitted by the DocumentIdConverterInterface when some data is available.

• DocumentIdConverterReady : the DocumentIdConverterInterface is ready, i.e. when it has finished getting the part instance ids that contain the given document, DocumentIdConverterInterface.getConversionResult can be called.
• DocumentIdConverterCancelled : the retrieving of the content by the DocumentIdConverterInterface has been cancelled.
