Enumeration DocumentContentGetterInterfaceSignal

The DocumentContentGetterInterfaceSignal lists all the signals that may be sent by the DocumentContentGetterInterface.

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

DocumentContentReady : the DocumentContentGetterInterface is ready, i.e. when it has finished downloading the content of an attached document.
DocumentContentCancelled : the retrieving of the content by the DocumentContentGetterInterface has been cancelled.

/** 
 * Sample to illustrate how to download an attached document.

// the DataSessionInterface has been created previously and is connected
let lDataSession : DataSessionInterface;
// user callback code called when the document data content is ready 
let myCallback : tListenerCallback;

// myCallback will be called when the data is available
