public class IIOByteBuffer extends Object
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 and Description |
|---|
IIOByteBuffer(byte[] data,
int offset,
int length)
Constructs an
IIOByteBuffer that references a
given byte array, offset, and length. |
| Modifier and Type | Method and Description |
|---|---|
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. |
void |
setLength(int length)
Updates the value that will be returned by subsequent calls
to the
getLength method. |
void |
setOffset(int offset)
Updates the value that will be returned by subsequent calls
to the
getOffset method. |
