com.basis.filesystem.Compare

public final class Compare
extends java.lang.Object

Check two files for data equivalence. For string or program files this is just checks byte equality, but for data files it just verifies the keys and data are the same.

Method Summary

Modifier and Type	Method and Description
static java.lang.String	bytesToString(byte[] p_bytes, int p_offset, int p_length)
static int	compare(byte[] p_left, int p_leftOffset, int p_leftLength, byte[] p_right, int p_rightOffset, int p_rightLength)
static boolean	compare(ConnectionMgr p_mgr, java.lang.String p_left, java.lang.String p_right, boolean p_recursive, java.io.PrintWriter p_out) This method will compare the files/directories at the paths specified and return true if they are equivalent.
static void	main(java.lang.String... args) Main method so that this can be called from the command line.

Method Detail

compare

public static boolean compare(ConnectionMgr p_mgr,
                              java.lang.String p_left,
                              java.lang.String p_right,
                              boolean p_recursive,
                              java.io.PrintWriter p_out)
                       throws FilesystemException

This method will compare the files/directories at the paths specified and return true if they are equivalent. If a PrintWriter is provided it will continue after the first difference and print the nature of the differences to the PrintWriter.

Parameters:

p_mgr - ConnectionMgr to use opening files.

p_left - Left path.

p_right - Right path.

p_recursive - true if it should recursively compare directory contents.

p_out - Optional PrintWriter for difference details, if they are the same then nothing out output.

Returns:

true if the files at the two paths are equivalent.

Throws:

FilesystemException

main

public static void main(java.lang.String... args)

Main method so that this can be called from the command line.

Parameters:

args -

                          byte[] p_right,
                          int p_rightOffset,
