MandatoryStreamCombination

Kotlin |Java

class MandatoryStreamCombination

kotlin.Any
↳	android.hardware.camera2.params.MandatoryStreamCombination

Immutable class to store the available mandatory stream combination.

A mandatory stream combination refers to a specific entry in the documented sets of required stream android.hardware.camera2.CameraDevice#createCaptureSession. These combinations of streams are required to be supported by the camera device.

The list of stream combinations is available by invoking CameraCharacteristics#get and passing key android.hardware.camera2.CameraCharacteristics#SCALER_MANDATORY_STREAM_COMBINATIONS.

Summary

Nested classes
	`MandatoryStreamInformation` Immutable class to store available mandatory stream information.

Public methods
Boolean	`equals(other: Any?)` Check if this `MandatoryStreamCombination` is equal to another `MandatoryStreamCombination`.
CharSequence	`getDescription()` Get the mandatory stream combination description.
MutableList<MandatoryStreamCombination.MandatoryStreamInformation!>	`getStreamsInformation()` Get information about each stream in the mandatory combination.
Int	`hashCode()` Returns a hash code value for the object.
Boolean	`isReprocessable()` Indicates whether the mandatory stream combination is reprocessable.

Public methods

equals

Added in API level 29

fun equals(other: Any?): Boolean

Check if this MandatoryStreamCombination is equal to another MandatoryStreamCombination.

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

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

Return
`Boolean`	`true` if the objects were equal, `false` otherwise

getDescription

Added in API level 29

fun getDescription(): CharSequence

Get the mandatory stream combination description.

Return
`CharSequence`	CharSequence with the mandatory combination description. This value cannot be `null`.

getStreamsInformation

Added in API level 29

fun getStreamsInformation(): MutableList<MandatoryStreamCombination.MandatoryStreamInformation!>

Get information about each stream in the mandatory combination.

Return
`MutableList<MandatoryStreamCombination.MandatoryStreamInformation!>`	Non-modifiable list of stream information. This value cannot be `null`.

hashCode

Added in API level 29

fun hashCode(): Int

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

Return
`Int`	a hash code value for this object.

isReprocessable

Added in API level 29

fun isReprocessable(): Boolean

Indicates whether the mandatory stream combination is reprocessable. Reprocessable is defined as a stream combination that contains one input stream (MandatoryStreamInformation#isInput return true).

Return
`Boolean`	`true` in case the mandatory stream combination contains an input, `false` otherwise.
