oracle.security.crypto.util.FixedByteArrayOutputStream
A fixed-size, unsynchronized ByteArrayOutptStream
, that provides access to the internal buffer for efficiency.
Field Summary | |
protected byte[] |
buf The buffer to contains the bytes written to this stream. |
protected int |
count The number of bytes written to this stream. |
Constructor Summary | |
FixedByteArrayOutputStream(byte[] buf) Creates a FixedByteArrayOutputStream using the given buffer. |
|
FixedByteArrayOutputStream(int size) Creates a FixedByteArrayOutputStream with a newly allocated buffer of the given size. |
