## Constants
### SESSION_HIGH_SPEED
Added in[API level 28](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public static final int SESSION_HIGH_SPEED
```
A high speed session type that can only contain instances of[OutputConfiguration](https://developer.android.com/reference/android/hardware/camera2/params/OutputConfiguration). The outputs can run using high speed FPS ranges. Calls to[setInputConfiguration(InputConfiguration)](https://developer.android.com/reference/android/hardware/camera2/params/SessionConfiguration#setInputConfiguration(android.hardware.camera2.params.InputConfiguration))are not supported.
When using this type, the CameraCaptureSession returned by[CameraCaptureSession.StateCallback](https://developer.android.com/reference/android/hardware/camera2/CameraCaptureSession.StateCallback)can be cast to a[CameraConstrainedHighSpeedCaptureSession](https://developer.android.com/reference/android/hardware/camera2/CameraConstrainedHighSpeedCaptureSession)to access the extra methods for constrained high speed recording.

### hashCode
Added in[API level 28](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
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](https://developer.android.com/reference/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](https://developer.android.com/reference/java/lang/Object#equals(java.lang.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](https://developer.android.com/reference/java/lang/Object#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.
| Returns ||
|-------|-------------------------------------------|
| `int` | a hash code value for this object.
|
### setColorSpace
Added in[API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public void setColorSpace (ColorSpace.Named colorSpace)
```
Set a specific device-supported color space.
Clients can choose from any profile advertised as supported in[CameraCharacteristics.REQUEST_AVAILABLE_COLOR_SPACE_PROFILES](https://developer.android.com/reference/android/hardware/camera2/CameraCharacteristics#REQUEST_AVAILABLE_COLOR_SPACE_PROFILES)queried using[ColorSpaceProfiles.getSupportedColorSpaces](https://developer.android.com/reference/android/hardware/camera2/params/ColorSpaceProfiles#getSupportedColorSpaces(int)). When set, the colorSpace will override the default color spaces of the output targets, or the color space implied by the dataSpace passed into an[ImageReader](https://developer.android.com/reference/android/media/ImageReader)'s constructor.
| Parameters ||
|--------------|--------------------------------------------------------|
| `colorSpace` | `ColorSpace.Named`: This value cannot be`null`.
|
### setInputConfiguration
Added in[API level 28](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public void setInputConfiguration (InputConfiguration input)
```
Sets the[InputConfiguration](https://developer.android.com/reference/android/hardware/camera2/params/InputConfiguration)for a reprocessable session. Input configuration are not supported for[SESSION_HIGH_SPEED](https://developer.android.com/reference/android/hardware/camera2/params/SessionConfiguration#SESSION_HIGH_SPEED).
| Parameters ||
|---------|-------------------------------------------------------------------------------|
| `input` | `InputConfiguration`: Input configuration. This value cannot be`null`.
|
| Throws ||
|------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| [UnsupportedOperationException](https://developer.android.com/reference/java/lang/UnsupportedOperationException) | In case it is called for[SESSION_HIGH_SPEED](https://developer.android.com/reference/android/hardware/camera2/params/SessionConfiguration#SESSION_HIGH_SPEED)type session configuration. |
### setSessionParameters
Added in[API level 28](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public void setSessionParameters (CaptureRequest params)
```
Sets the session wide camera parameters (see[CaptureRequest](https://developer.android.com/reference/android/hardware/camera2/CaptureRequest)). This argument can be set for every supported session type and will be passed to the camera device as part of the capture session initialization. Session parameters are a subset of the available capture request parameters (see[CameraCharacteristics.getAvailableSessionKeys](https://developer.android.com/reference/android/hardware/camera2/CameraCharacteristics#getAvailableSessionKeys())) and their application can introduce internal camera delays. To improve camera performance it is suggested to change them sparingly within the lifetime of the capture session and to pass their initial values as part of this method.
| Parameters ||
|----------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `params` | `CaptureRequest`: A capture request that includes the initial values for any available session wide capture keys. Tags (see[CaptureRequest.Builder.setTag](https://developer.android.com/reference/android/hardware/camera2/CaptureRequest.Builder#setTag(java.lang.Object))) and output targets (see[CaptureRequest.Builder.addTarget](https://developer.android.com/reference/android/hardware/camera2/CaptureRequest.Builder#addTarget(android.view.Surface))) are ignored if set. Parameter values not part of[CameraCharacteristics.getAvailableSessionKeys](https://developer.android.com/reference/android/hardware/camera2/CameraCharacteristics#getAvailableSessionKeys())will also be ignored. It is recommended to build the session parameters using the same template type as the initial capture request, so that the session and initial request parameters match as much as possible.

### setStateCallback
Added in[API level 35](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public void setStateCallback (Executor executor,
CameraCaptureSession.StateCallback cb)
```
Set the state callback and executor.
This function must be called for the SessionConfiguration object created via[SessionConfiguration(int, List)](https://developer.android.com/reference/android/hardware/camera2/params/SessionConfiguration#SessionConfiguration(int,%20java.util.List))before it's used to create a capture session.
| Parameters ||
|------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `executor` | `Executor`: The executor which should be used to invoke the callback. In general it is recommended that camera operations are not done on the main (UI) thread. This value cannot be`null`. Callback and listener events are dispatched through this[Executor](https://developer.android.com/reference/java/util/concurrent/Executor), providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can use[Context.getMainExecutor()](https://developer.android.com/reference/android/content/Context#getMainExecutor()). Otherwise, provide an[Executor](https://developer.android.com/reference/java/util/concurrent/Executor)that dispatches to an appropriate thread.
|
| `cb` | `CameraCaptureSession.StateCallback`: A state callback interface implementation. This value cannot be`null`.
|
### writeToParcel
Added in[API level 29](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public void writeToParcel (Parcel dest,
int flags)
```
Flatten this object in to a Parcel.
| Parameters ||
|---------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `dest` | `Parcel`: The Parcel in which the object should be written. This value cannot be`null`.
|
| `flags` | `int`: Additional flags about how the object should be written. May be 0 or[Parcelable.PARCELABLE_WRITE_RETURN_VALUE](https://developer.android.com/reference/android/os/Parcelable#PARCELABLE_WRITE_RETURN_VALUE). Value is either`0`or a combination of[Parcelable.PARCELABLE_WRITE_RETURN_VALUE](https://developer.android.com/reference/android/os/Parcelable#PARCELABLE_WRITE_RETURN_VALUE), and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
