class
DeviceStateSensorOrientationMap
extends Object
| java.lang.Object | |
| ↳ | android.hardware.camera2.params.DeviceStateSensorOrientationMap |
Immutable class that maps the device fold state to sensor orientation.
Some logical
cameras on foldables can include physical sensors with different sensor orientation
values. As a result, the values of the logical camera device can potentially change depending
on the device fold state.
The device fold state to sensor orientation map will contain information about the respective logical camera sensor orientation given a device state. Clients can query the mapping for all possible supported folded states.

Constants | |
|---|---|
long |
FOLDED
The device is folded. |
long |
NORMAL
The device is in its normal physical configuration. |
Public methods | |
|---|---|
boolean
|
equals(Object obj)
Check if this DeviceStateSensorOrientationMap is equal to another DeviceStateSensorOrientationMap. |
int
|
getSensorOrientation(long deviceState)
Return the logical camera sensor orientation given a specific device fold state. |

hashCode()
Returns a hash code value for the object. |
Inherited methods | |
|---|---|
public static final long FOLDED
The device is folded. If not set, the device is unfolded or does not support folding. The exact point when this status change happens during the folding operation is device-specific.
Constant Value: 4 (0x0000000000000004)
public static final long NORMAL
The device is in its normal physical configuration. This is the default if the device does not support multiple different states.
Constant Value: 0 (0x0000000000000000)
public boolean equals (Object obj)
Check if this DeviceStateSensorOrientationMap is equal to another DeviceStateSensorOrientationMap.
Two device state orientation maps are equal if and only if all of their elements are
equal.
| Parameters | |
|---|---|
obj |
Object: the reference object with which to compare. |
| Returns | |
|---|---|
boolean |
true if the objects were equal, false otherwise |
public int getSensorOrientation (long deviceState)
Return the logical camera sensor orientation given a specific device fold state.
| Parameters | |
|---|---|
deviceState |
long: Device fold state
Value is NORMAL, or FOLDED |
| Returns | |
|---|---|
int |
Valid CameraCharacteristics.SENSOR_ORIENTATION for
any supported device fold state |
| Throws | |
|---|---|
IllegalArgumentException |
if the given device state is invalid |
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:
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.
equals(Object)
method, then calling the hashCode method on each of
the two objects must produce the same integer result.
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.)
