java.lang.Objectjavax.imageio.stream.IIOByteBuffer
A class representing a mutable reference to an array of bytes and
an offset and length within that array. IIOByteBuffer
is used by ImageInputStream to supply a sequence of bytes
to the caller, possibly with fewer copies than using the conventional
read methods that take a user-supplied byte array.
The byte array referenced by an IIOByteBuffer will
generally be part of an internal data structure belonging to an
ImageReader implementation; its contents should be
considered read-only and must not be modified.
| Constructor Summary | |
IIOByteBuffer(byte[] data,
int offset,
int length)
Constructs an IIOByteBuffer that references a
given byte array, offset, and length. |

| Method Summary | |
byte[] |
getData()
Returns a reference to the byte array. |
int |
getLength()
Returns the length of the data of interest within the byte array returned by getData. |
int |
getOffset()
Returns the offset within the byte array returned by getData at which the data of interest start. |
void |
setData(byte[] data)
Updates the array reference that will be returned by subsequent calls to the getData method. |
