void |
close()
Finishes writing to the underlying stream, but does NOT close the underlying stream.
|
void |
finish()

void |
flush()
Flushes the underlying stream, but leaves the internal buffer alone.
|
protected void |
flushCache()
Writes the cache out onto the underlying stream
|
protected void |
flushCacheWithAppend(byte[] bufferToAppend,
int off,
int len)
Writes the cache and bufferToAppend to the underlying stream
as one large chunk
|
void |
write(byte[] b)
Writes the array.

void |
write(byte[] src,
int off,
int len) |
void |
write(int b)
Write the specified byte to our output stream.
