Method Detail

contentEquals

public static boolean contentEquals(ReadableByteChannel channel1,
                                    ReadableByteChannel channel2,
                                    int bufferCapacity)
                             throws IOException

Tests if two readable byte channel contents are equal starting at their respective current positions.

Parameters:

channel1 - A readable byte channel.

channel2 - Another readable byte channel.

bufferCapacity - The two internal buffer capacities, in bytes.

Returns:

true if the contents of both RandomAccessFiles are equal, false otherwise.

Throws:

IOException - if an I/O error occurs or the timeout is met.

contentEquals

public static boolean contentEquals(SeekableByteChannel channel1,
                                    SeekableByteChannel channel2,
                                    int bufferCapacity)
                             throws IOException

Tests if two seekable byte channel contents are equal starting at their respective current positions.

If the two channels have different sizes, no content comparison takes place, and this method returns false.

Parameters:

channel1 - A seekable byte channel.

channel2 - Another seekable byte channel.

bufferCapacity - The two internal buffer capacities, in bytes.

Returns:

true if the contents of both RandomAccessFiles are equal, false otherwise.

Throws:

IOException - if an I/O error occurs or the timeout is met.
