net.rim.device.api.io.NoCopyByteArrayOutputStream
public class NoCopyByteArrayOutputStream
Byte array output stream that returns handle to the underlying data buffer, not a copy.
This class acts exactly like a standard byte array output stream, with two exceptions:
NoCopyByteArrayOutputStream.getByteArray() retrieves a handle to the underlying data
buffer, and not a copy of that buffer.

public NoCopyByteArrayOutputStream()
Builds a new byte array output stream with an initial buffer size of 32 bytes.
public NoCopyByteArrayOutputStream(int size)
size - Initial size for the buffer.
public NoCopyByteArrayOutputStream(byte[] buffer,
int offset)
buffer - Byte array to share as output stream buffer.offset - Initial write position.| Method Detail |
|---|
public byte[] getByteArray()
Unlike ByteArrayOutputStream.toByteArray(), this method does
not create a copy of the buffer. The returned byte array will
probably be bigger than the actual size of the output stream. Use
ByteArrayOutputStream.size() to get the actual size of the stream.
