createOutputStream() → {Guacamole.OutputStream}

Allocates an available stream index and creates a new Guacamole.OutputStream using that index, associating the resulting stream with this Guacamole.Client. Note that this stream will not yet exist as far as the other end of the Guacamole connection is concerned. Streams exist within the Guacamole protocol only when referenced by an instruction which creates the stream, such as a "clipboard", "file", or "pipe" instruction.

Returns:
A new Guacamole.OutputStream with a newly-allocated index and associated with this Guacamole.Client.

Source:

endStream(index)

Marks a currently-open stream as complete. The other end of the Guacamole connection will be notified via an "end" instruction that the stream is closed, and the index will be made available for reuse in future streams.
Parameters:
Name Type Description
index Number The index of the stream to end.
Source:

exportState(callback)

Produces an opaque representation of Guacamole.Client state which can be later imported through a call to importState(). This object is effectively an independent, compressed snapshot of protocol and display state. Invoking this function implicitly flushes the display.
Parameters:
Name Type Description
callback function Callback which should be invoked once the state object is ready. The state object will be passed to the callback as the sole parameter. This callback may be invoked immediately, or later as the display finishes rendering and becomes ready.
Source:

getDisplay() → {Guacamole.Display}

Returns the underlying display of this Guacamole.Client. The display contains an Element which can be added to the DOM, causing the display to become visible.
Source:
Returns:
The underlying display of this Guacamole.Client.
Type
Guacamole.Display

importState(state, callbackopt)

Restores Guacamole.Client protocol and display state based on an opaque object from a prior call to exportState(). The Guacamole.Client instance used to export that state need not be the same as this instance.
Parameters:
Name Type Attributes Description
state Object An opaque representation of Guacamole.Client state from a prior call to exportState().
callback function <optional>
 The function to invoke when state has finished being imported. This may happen immediately, or later as images within the provided state object are loaded.
Source:

requestObjectInputStream(index, name)

Requests read access to the input stream having the given name. If successful, a new input stream will be created.
Parameters:
Name Type Description
index Number The index of the object from which the input stream is being requested.
name String The name of the input stream to request.
Source:

sendAck(index, message, code)

Acknowledge receipt of a blob on the stream with the given index.
