 javax.imageio.stream.IIOByteBuffer
| IIOByteBuffer | | public class IIOByteBuffer (Code) | | 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 | |
| public | IIOByteBuffer(byte[] data, int offset, int length)
Constructs an IIOByteBuffer that references a
given byte array, offset, and length. |
| Method Summary | |
| public byte[] | getData()
Returns a reference to the byte array. | | public int | getLength()
Returns the length of the data of interest within the byte
array returned by getData. | | public int | getOffset()
Returns the offset within the byte array returned by
getData at which the data of interest start. | | public void | setData(byte[] data)
Updates the array reference that will be returned by subsequent calls
to the getData method. | | public void | setLength(int length)
Updates the value that will be returned by subsequent calls
to the getLength method. | | public void | setOffset(int offset)
Updates the value that will be returned by subsequent calls
to the getOffset method. |
| IIOByteBuffer | | public IIOByteBuffer(byte[] data, int offset, int length)(Code) | | Constructs an IIOByteBuffer that references a
given byte array, offset, and length.
Parameters:
data - a byte array.
Parameters:
offset - an int offset within the array.
Parameters:
length - an int specifying the length of the data ofinterest within byte array, in bytes. |
| setData | | public void setData(byte[] data)(Code) | | Updates the array reference that will be returned by subsequent calls
to the getData method.
Parameters:
data - a byte array reference containing the new data value.

| setLength | | public void setLength(int length)(Code) | | Updates the value that will be returned by subsequent calls
to the getLength method.
Parameters:
length - an int containing the new length value.
See Also: IIOByteBuffer.getLength |
| setOffset | | public void setOffset(int offset)(Code) | | Updates the value that will be returned by subsequent calls
to the getOffset method.
Parameters:
offset - an int containing the new offset value.
