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 inequals
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
method, then calling thehashCode
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
method, then calling thehashCode
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.
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.
