class
MandatoryStreamCombination
extends Object
java.lang.Object | |
↳ | 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 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
CameraCharacteristics.SCALER_MANDATORY_STREAM_COMBINATIONS
.

MandatoryStreamCombination.MandatoryStreamInformation
Immutable class to store available mandatory stream information. |
Public methods | |
---|---|
boolean
|
equals(Object obj)
Check if this |
CharSequence
|
getDescription()
Get the mandatory stream combination description. |
List<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. |
Inherited methods | |
---|---|
public boolean equals (Object obj)
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 |
Object : the reference object with which to compare. |
Returns | |
---|---|
boolean |
true if the objects were equal, false otherwise |
public CharSequence getDescription ()
Get the mandatory stream combination description.
Returns | |
---|---|
CharSequence |
CharSequence with the mandatory combination description.
This value cannot be null . |
public List<MandatoryStreamCombination.MandatoryStreamInformation> getStreamsInformation ()
Get information about each stream in the mandatory combination.
Returns | |
---|---|
List<MandatoryStreamCombination.MandatoryStreamInformation> |
Non-modifiable list of stream information.
This value cannot be null . |
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:
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.
equals(Object)
method, then calling the hashCode
method on each of
the two objects must produce the same integer result.
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. |
public boolean isReprocessable ()
Indicates whether the mandatory stream combination is reprocessable. Reprocessable is defined
as a stream combination that contains one input stream
(MandatoryStreamInformation#isInput
return true).
Returns | |
---|---|
boolean |
true in case the mandatory stream combination contains an input,
false otherwise. |
