MultiResolutionStreamInfo

public class MultiResolutionStreamInfo
extends Object

java.lang.Object
   ↳ android.hardware.camera2.params.MultiResolutionStreamInfo


A utility class describing the properties of one stream of fixed-size image buffers backing a multi-resolution image stream.

A group of MultiResolutionStreamInfo are used to describe the properties of a multi-resolution image stream for a particular format. The MultiResolutionImageReader class represents a multi-resolution output stream, and is constructed using a group of MultiResolutionStreamInfo. A group of MultiResolutionStreamInfo can also be used to create a multi-resolution reprocessable camera capture session. See InputConfiguration for details.

Summary

Public constructors

MultiResolutionStreamInfo(int streamWidth, int streamHeight, String physicalCameraId)

Create a new MultiResolutionStreamInfo.

Public methods

boolean equals(Object obj)

Check if this MultiResolutionStreamInfo is equal to another MultiResolutionStreamInfo.

int getHeight()

The height of this particular image buffer stream in pixels.

String getPhysicalCameraId()

The physical camera Id of this particular image buffer stream.

int getWidth()

The width of this particular image buffer stream in pixels.

int hashCode()

Returns a hash code value for the object.

Inherited methods

Public constructors

MultiResolutionStreamInfo

Added in API level 31
public MultiResolutionStreamInfo (int streamWidth, 
                int streamHeight, 
                String physicalCameraId)

Create a new MultiResolutionStreamInfo.

This class creates a MultiResolutionStreamInfo using image width, image height, and the physical camera Id images originate from.

Normally applications do not need to create these directly. Use MultiResolutionStreamConfigurationMap.getOutputInfo(int) or MultiResolutionStreamConfigurationMap.getInputInfo(int) to obtain them for a particular format instead.

Parameters
streamWidth int: The width in pixels of the camera stream Value is 1 or greater

streamHeight int: The height in pixels of the camera stream Value is 1 or greater

physicalCameraId String: The physical camera Id the camera stream is associated with This value cannot be null.

Throws
IllegalArgumentException if the streamWidth or streamHeight is invalid (either zero or negative).

Public methods

equals

Added in API level 31
public boolean equals (Object obj)

Check if this MultiResolutionStreamInfo is equal to another MultiResolutionStreamInfo.

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

Returns
boolean true if the objects were equal, false otherwise

getHeight

Added in API level 31
public int getHeight ()

The height of this particular image buffer stream in pixels.

Returns
int Value is 1 or greater

getPhysicalCameraId

Added in API level 31
public String getPhysicalCameraId ()

The physical camera Id of this particular image buffer stream.

Returns
String This value cannot be null.

getWidth

Added in API level 31
public int getWidth ()

The width of this particular image buffer stream in pixels.

Returns
int Value is 1 or greater

hashCode

Added in API level 31
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 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 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.

Returns
int a hash code value for this object.
