CameraCharacteristics.Key

extends Object
java.lang.Object
   ↳ android.hardware.camera2.CameraCharacteristics.Key<T>

Class Overview

A Key is used to do camera characteristics field lookups with get(CameraCharacteristics.Key).

For example, to get the stream configuration map: 

 StreamConfigurationMap map = cameraCharacteristics.get(
      CameraCharacteristics.SCALER_STREAM_CONFIGURATION_MAP);

To enumerate over all possible keys for CameraCharacteristics, see getKeys().

Public Methods

public final boolean equals (Object o)

Compares this instance with the specified object and indicates if they are equal. In order to be equal, o must represent the same object as this instance using a class-specific comparison. The general contract is that this comparison should be reflexive, symmetric, and transitive. Also, no object reference other than null is equal to null.

The default implementation returns true only if this == o. See Writing a correct equals method if you intend implementing your own equals method.

The general contract for the equals and hashCode() methods is that if equals returns true for any two objects, then hashCode() must return the same value for these objects. This means that subclasses of Object usually override either both methods or neither of them.

Parameters
o the object to compare this instance with.
Returns
  • true if the specified object is equal to this Object; false otherwise.

public String getName ()

Return a camelCase, period separated name formatted like: "root.section[.subsections].name".

Built-in keys exposed by the Android SDK are always prefixed with "android."; keys that are device/platform-specific are prefixed with "com.".

For example, CameraCharacteristics.SCALER_STREAM_CONFIGURATION_MAP would have a name of "android.scaler.streamConfigurationMap"; whereas a device specific key might look like "com.google.nexus.data.private".

Returns
  • String representation of the key name

public final int hashCode ()

Returns an integer hash code for this object. By contract, any two objects for which equals(Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

Note that hash values must not change over time unless information used in equals comparisons also changes.

See Writing a correct hashCode method if you intend implementing your own hashCode method.

Returns
  • this object's hash code.
