MarshalQueryablePrimitive

public final class MarshalQueryablePrimitive extends Object implements android.hardware.camera2.marshal.MarshalQueryable
Marshal/unmarshal built-in primitive types to and from a {@link ByteBuffer}.

The following list of type marshaling is supported:

  • byte <-> TYPE_BYTE
  • int <-> TYPE_INT32
  • long <-> TYPE_INT64
  • float <-> TYPE_FLOAT
  • double <-> TYPE_DOUBLE
  • Rational <-> TYPE_RATIONAL

Due to the nature of generics, values are always boxed; this also means that both the boxed and unboxed types are supported (i.e. both {@code int} and {@code Integer}).

Each managed type must correspond 1:1 to the native type (e.g. a byte will not map to a {@link CameraMetadataNative#TYPE_INT32 TYPE_INT32} or vice versa) for marshaling.
