// Description : This is the primary interface to on/off button
|
|
// devices associated with a ClientBase. This creates a
|
|
// node that connects to the named button device, if it
|
|
// exists, and provides hooks to the user to read the
|
|
// state of any of the sequentially numbered buttons
|
|
// associated with that device.
|
|
//
|
|
// It also can associate an arbitrary ButtonHandle with
|
|
// each button; when buttons are associated with
|
|
// ButtonHandles, this node will put appropriate up and
|
|
// down events on the data graph for each button state
|
|
// change.
