Inherited methods

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

Public methods

getAxis

Added in API level 12

public int getAxis ()

Gets the axis id.

Returns
`int`	The axis id.

getFlat

Added in API level 9

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

Added in API level 9

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

Added in API level 9

public float getMax ()

Gets the inclusive maximum value for the axis.

Returns
`float`	The inclusive maximum value.

getMin

Added in API level 9

public float getMin ()

Gets the inclusive minimum value for the axis.

Returns
`float`	The inclusive minimum value.

getRange

Added in API level 9

public float getRange ()

Gets the range of the axis (difference between maximum and minimum).

Returns
`float`	The range of values.

getResolution

Added in API level 18

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

Added in API level 12

public int getSource ()

Gets the source for which the axis is defined.

Returns
`int`	The source.

isFromSource

Added in API level 18

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.
