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`.

`final void`	`wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.

Public constructors

OisSample

public OisSample (long timestamp, 
                float xShift, 
                float yShift)

Create a new OisSample.

OisSample contains the timestamp and the amount of shifts in x and y direction, in pixels, of the OIS sample.

A positive value for a shift in x direction is a shift from left to right in active array coordinate system. For example, if the optical center is (1000, 500) in active array coordinates, a shift of (3, 0) puts the new optical center at (1003, 500).

A positive value for a shift in y direction is a shift from top to bottom in active array coordinate system. For example, if the optical center is (1000, 500) in active array coordinates, a shift of (0, 5) puts the new optical center at (1000, 505).

xShift and yShift must be finite; NaN and infinity is not allowed.

Parameters
`timestamp`	`long`: timestamp of the OIS sample.
`xShift`	`float`: shift of the OIS sample in x direction.
`yShift`	`float`: shift of the OIS sample in y direction.

Throws
`IllegalArgumentException`	if xShift or yShift is not finite

Public methods

equals

public boolean equals (Object obj)

Check if this OisSample is equal to another OisSample.

Two samples are only equal if and only if each of the OIS information is equal.

Parameters
`obj`	`Object`: the reference object with which to compare.

Returns
`boolean`	`true` if the objects were equal, `false` otherwise

getTimestamp

public long getTimestamp ()

Get the timestamp in nanoseconds.

The timestamps are in the same timebase as and comparable to android.sensor.timestamp.

Returns
`long`	a long value (guaranteed to be finite)

getXshift

public float getXshift ()

Get the shift in x direction.

Returns
`float`	a floating point value (guaranteed to be finite)

getYshift

public float getYshift ()

Get the shift in y direction.

Returns
`float`	a floating point value (guaranteed to be finite)

hashCode

public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
It is not required that if two objects are unequal according to the equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)

Returns
`int`	a hash code value for this object.

toString

public String toString ()

Return the OisSample as a string representation.

"OisSample{timestamp:%l, shift_x:%f, shift_y:%f}" represents the OIS sample's timestamp, shift in x direction, and shift in y direction.

Returns
`String`	string representation of `OisSample`
