                 MergeRule

A rule specifying how to merge chunks in a ChunkString, using two matching tag patterns: a left pattern, and a right pattern. When applied to a ChunkString, it will find any chunk whose end matches left pattern, and immediately followed by a chunk whose beginning matches right pattern. It will then merge those two chunks into a single chunk.

Method Details [hide private]

__init__(self, left_tag_pattern, right_tag_pattern, descr)
(Constructor)

source code 

Construct a new MergeRule.

Parameters:
  • right_tag_pattern (string) - This rule's right tag pattern. When applied to a ChunkString, this rule will find any chunk whose end matches left_tag_pattern, and immediately followed by a chunk whose beginning matches this pattern. It will then merge those two chunks into a single chunk.
  • left_tag_pattern (string) - This rule's left tag pattern. When applied to a ChunkString, this rule will find any chunk whose end matches this pattern, and immediately followed by a chunk whose beginning matches right_tag_pattern. It will then merge those two chunks into a single chunk.
  • descr (string) - A short description of the purpose and/or effect of this rule.
Overrides: RegexpChunkRule.__init__

__repr__(self)
(Representation operator)

source code 
Returns: string
A string representation of this rule. This string representation has the form: 
   <MergeRule: '<NN|DT|JJ>', '<NN|JJ>'>

Note that this representation does not include the description string; that string can be accessed separately with the descr method.

Overrides: RegexpChunkRule.__repr__
