## org.tmatesoft.svn.core.io.diff
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.

Since:
  1.2
Version:
  1.3

Method Summary
`String` | `close()` Closes the source and target streams, finalizes the checksum computation and returns it in a hex representation.
`static SVNDiffWindowApplyBaton` | `create(File source, File target, MessageDigest digest)` Creates a diff window apply baton whith source and target streams represented by files.
`static SVNDiffWindowApplyBaton` | `create(InputStream source, OutputStream target, MessageDigest digest)` Creates a diff window apply baton whith initial source and target streams.

Method Detail

### create

    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
  Throws:
    `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.
