extends ServletOutputStream

an output stream wrapper to cache response bytes

Constructor Summary

CachingOutputStreamWrapper()

Method Summary

void	close() Close this output stream, causing any buffered data to be flushed and any further output data to throw an IOException.
void	flush() Flush any buffered data for this output stream, which also causes the response to be committed.
byte[]	getBytes() return the cached bytes
void	write(byte[] b) Write b.length bytes from the specified byte array to our output stream.
void	write(byte[] b, int off, int len) Write len bytes from the specified byte array, starting at the specified offset, to our output stream.
