Method Detail

readStream

public static byte[] readStream(int length,
                                java.io.InputStream is)
                         throws java.io.IOException

Throws:

java.io.IOException

writeStream

public static void writeStream(java.io.InputStream is,
                               java.io.OutputStream os)
                        throws java.io.IOException

Throws:

java.io.IOException

updateCRCWithStream

public static void updateCRCWithStream(java.io.InputStream is,
                                       java.util.zip.CRC32 crc)
                                throws java.io.IOException

Calculate a checksum for the stream.

Parameters:

is - InputStream the stream for which to calculate the checksum.

crc - the checksum object to update.

Throws:

java.io.IOException - problem in the I/O processing.

areEqual

public static boolean areEqual(java.io.InputStream isA,
                               java.io.InputStream isB)
                        throws java.io.IOException

Compares two InputStreams for equality. Both streams are read and the content is compared.

Parameters:

isA - first stream to compare

isB - second stream to compare

Returns:

true if the streams have equal data, false otherwise.

Throws:

java.io.IOException - a problem in the I/O processing.
