MandatoryStreamCombination.MandatoryStreamInformation

public static final class MandatoryStreamCombination.MandatoryStreamInformation
extends Object

java.lang.Object
   ↳ android.hardware.camera2.params.MandatoryStreamCombination.MandatoryStreamInformation


Immutable class to store available mandatory stream information.

Summary

Public methods

boolean equals(Object obj)

Check if this MandatoryStreamInformation is equal to another MandatoryStreamInformation.

List<Size> getAvailableSizes()

Return the list of available sizes for this mandatory stream.

int getFormat()

Retrieve the mandatory stream format.

int hashCode()

Returns a hash code value for the object.

boolean isInput()

Confirms whether or not this is an input stream.

Inherited methods

Public methods

equals

public boolean equals (Object obj)

Check if this MandatoryStreamInformation is equal to another MandatoryStreamInformation.

Two vectors are only equal if and only if each of the respective elements is equal.

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

Returns
boolean true if the objects were equal, false otherwise

getAvailableSizes

public List<Size> getAvailableSizes ()

Return the list of available sizes for this mandatory stream.

Per documented CameraDevice#createCaptureSession the largest resolution in the result will be tested and guaranteed to work. If clients want to use smaller sizes, then the resulting session configuration can be tested either by calling CameraDevice#createCaptureSession or CameraDevice#isSessionConfigurationSupported.

Returns
List<Size> non-modifiable ascending list of available sizes. This value cannot be null.

getFormat

public int getFormat ()

Retrieve the mandatory stream format.

Returns
int integer format. Value is ImageFormat.UNKNOWN, ImageFormat.RGB_565, ImageFormat.YV12, ImageFormat.Y8, android.graphics.ImageFormat.Y16, ImageFormat.NV16, ImageFormat.NV21, ImageFormat.YUY2, ImageFormat.JPEG, ImageFormat.DEPTH_JPEG, ImageFormat.YUV_420_888, ImageFormat.YUV_422_888, ImageFormat.YUV_444_888, ImageFormat.FLEX_RGB_888, ImageFormat.FLEX_RGBA_8888, ImageFormat.RAW_SENSOR, ImageFormat.RAW_PRIVATE, ImageFormat.RAW10, ImageFormat.RAW12, ImageFormat.DEPTH16, ImageFormat.DEPTH_POINT_CLOUD, android.graphics.ImageFormat.RAW_DEPTH, ImageFormat.PRIVATE, or ImageFormat.HEIC

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.

isInput

public boolean isInput ()

Confirms whether or not this is an input stream.

Returns
boolean true in case the stream is input, false otherwise.
