      private static final SVNPatchFileStream.SVNPatchFileLineFilter original_line_filter
      A stream line-filter which allows only original text from a hunk, and filters special lines (which start with a backslash).
    • modified_line_filter

      private static final SVNPatchFileStream.SVNPatchFileLineFilter modified_line_filter
      A stream line-filter which allows only modified text from a hunk, and filters special lines (which start with a backslash).
    • remove_leading_char_transformer

      private static final SVNPatchFileStream.SVNPatchFileLineTransformer remove_leading_char_transformer
      Line-transformer callback to shave leading diff symbols.

    • originalText

      private SVNPatchFileStream originalText
