A device, attached to the ClientBase by a AnalogNode, that records the data from a single named analog device.
The named device can contain any number of analog controls, numbered in sequence beginning at zero.
Each analog control returns a value ranging from -1 to 1, reflecting the current position of the control within its total range of motion.
Definition at line 34 of file clientAnalogDevice.h.
|
inline |
Returns the current position of indicated analog control (identified by its index number), or 0.0 if the control is unknown.
The normal range of a single control is -1.0 to 1.0.
Definition at line 77 of file clientAnalogDevice.I.
|
inline |
Returns the number of analog controls known to the ClientAnalogDevice.
This number may change as more controls are discovered.
Definition at line 47 of file clientAnalogDevice.I.
|
inline |
Returns true if the state of the indicated analog control is known, or false if we have never heard anything about this particular control.
Definition at line 93 of file clientAnalogDevice.I.
|
inline |
Sets the state of the indicated analog index.
The caller should ensure that acquire() is in effect while this call is made. This should be a number in the range -1.0 to 1.0, representing the current position of the control within its total range of movement.
Definition at line 61 of file clientAnalogDevice.I.
void ClientAnalogDevice::write_controls | ( | ostream & | out, |
int | indent_level | ||
) | const |
Writes a multi-line description of the current analog control states.
