Class SVNDiffWindowApplyBaton

java.lang.Object
org.tmatesoft.svn.core.io.diff.SVNDiffWindowApplyBaton

public class SVNDiffWindowApplyBaton extends Object
The SVNDiffWindowApplyBaton class is used to provide the source and target streams during applying diff windows. Also an instance of SVNDiffWindowApplyBaton may be supplied with an MD5 digest object for on-the-fly updating it with the bytes of the target view. So that when a diff window's instructions are applied, the digest will be the checksum for the full expanded text written to the target stream during delta application.

      public static SVNDiffWindowApplyBaton create(File source, File target, MessageDigest digest) throws SVNException
      Creates a diff window apply baton whith source and target streams represented by files.
      Parameters:
      source - a source file (from where the source views would be taken)
      target - a target file where the full text is written
      digest - an MD5 checksum for the full text that would be updated after each instruction applying
      Returns:
      a new SVNDiffWindowApplyBaton object

      SVNException
    • create

      public static SVNDiffWindowApplyBaton create(InputStream source, OutputStream target, MessageDigest digest)
      Creates a diff window apply baton whith initial source and target streams.
      Parameters:
      source - a source input stream (from where the source views would be taken)
      target - a target output stream where the full text is written
      digest - an MD5 checksum for the full text that would be updated after each instruction applying
      Returns:
      a new SVNDiffWindowApplyBaton object
    • close

      public String close()
      Closes the source and target streams, finalizes the checksum computation and returns it in a hex representation.
      Returns:
      an MD5 checksum in a hex representation.
