Parameters:

maxLength - the maximum length in memory

ByteArrayIOFileStream

public ByteArrayIOFileStream(InputStream is,
                     long maxLength)

creates an input output stream class from any stream if is alraedy is a buffered inputstream, no copy is made

Parameters:

is - the inputstream to buffer

maxLength - the maximum length in memory

ByteArrayIOFileStream

public ByteArrayIOFileStream(File f,
                     long maxLength,
