public final class StreamConfiguration extends Object
configurations
to set up
Surfaces
for creating a capture session
with CameraDevice.createCaptureSession(java.util.List<android.view.Surface>, android.hardware.camera2.CameraCaptureSession.StateCallback, android.os.Handler)
.
This is the authoritative list for all input/output formats (and sizes respectively for that format) that are supported by a camera device.

public boolean equals(Object obj)
StreamConfiguration
is equal to another StreamConfiguration

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

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.
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.
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
JavaTM programming language.)
