Public methods
getAxis
public int getAxis ()
Gets the axis id.
| Returns | |
|---|---|
int |
The axis id. |
getFlat
public float getFlat ()
Gets the extent of the center flat position with respect to this axis.
For example, a flat value of 8 means that the center position is between -8 and +8. This value is mainly useful for calibrating self-centering devices.
| Returns | |
|---|---|
float |
The extent of the center flat position. |
getFuzz
public float getFuzz ()
Gets the error tolerance for input device measurements with respect to this axis.
For example, a value of 2 indicates that the measured value may be up to +/- 2 units away from the actual value due to noise and device sensitivity limitations.
| Returns | |
|---|---|
float |
The error tolerance. |
getMax
public float getMax ()
Gets the inclusive maximum value for the axis.
| Returns | |
|---|---|
float |
The inclusive maximum value. |
getMin
public float getMin ()
Gets the inclusive minimum value for the axis.
| Returns | |
|---|---|
float |
The inclusive minimum value. |
getRange
public float getRange ()
Gets the range of the axis (difference between maximum and minimum).
| Returns | |
|---|---|
float |
The range of values. |
getResolution
public float getResolution ()
Gets the resolution for input device measurements with respect to this axis.
| Returns | |
|---|---|
float |
The resolution in units per millimeter, or units per radian for rotational axes. |
getSource
public int getSource ()
Gets the source for which the axis is defined.
| Returns | |
|---|---|
int |
The source. |
isFromSource
public boolean isFromSource (int source)
Determines whether the event is from the given source.
| Parameters | |
|---|---|
source |
int: The input source to check against. This can be a specific device type,
such as InputDevice#SOURCE_TOUCH_NAVIGATION, or a more generic device class,
such as InputDevice#SOURCE_CLASS_POINTER. |
| Returns | |
|---|---|
boolean |
Whether the event is from the given source. |
