47 An AbsValuator, used for EV_ABS events stores a value as well as other
104 A linux kernel "evdev" device sends a stream of "input events".
105 These events are grouped together into "input reports", which is a set of
106 input events ending in a single EV_SYN/SYN_REPORT event.
115 Absolute valuators are only for EV_ABS events. They have more fields:
120 The evdev protocol is stateful. Input events are only sent when the values
122 events emenating from the kernel.
140 valuator events apply.
158 self.events = {} # dict { ev_type : dict { ev_code : Valuator } }
182 Returns True for EV_SYN/SYN_REPORT events to indicate that a complete
185 Returns False for other events.
187 Events not supported by this device are silently ignored.
189 For MT events, updates the slot valuator value for the current slot.
190 If current slot is the 'primary' slot, also updates the events entry.
192 For all other events, updates the corresponding valuator value.
