- Field Detail
  - COMPARATOR
```
public static final java.util.Comparator COMPARATOR
```
    Compare function for sorting hunks after parsing. We sort hunks by their original line offset.
  - original_line_filter
```
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.
  - diffText
```
private SVNPatchFileStream diffText
```
    The hunk's unidiff text as it appeared in the patch file, without range information.
  - originalText
```
private SVNPatchFileStream originalText
```
    The original and modified texts in the hunk range. Derived from the diff text. For example, consider a hunk such as:
  - modifiedText
```
private SVNPatchFileStream modifiedText
```
  - original
```
private SVNPatchHunk.SVNPatchHunkRange original
```
    Hunk ranges as they appeared in the patch file. All numbers are lines, not bytes.
  - modified
```
private SVNPatchHunk.SVNPatchHunkRange modified
```
  - leadingContext
```
private long leadingContext
```
    Number of lines starting with ' ' before first '+' or '-'.
  - trailingContext
```
private long trailingContext
```
    Number of lines starting with ' ' after last '+' or '-'.

    Throws:
    
    java.io.IOException
    
    SVNException

                                  java.lang.StringBuffer range)
```
    Try to parse a hunk range specification from the string RANGE. Return parsed information in START and LENGTH, and return TRUE if the range parsed correctly. Note: This function may modify the input value RANGE.
  - parseOffset
```
