Detailed Description

A pattern to match one word, or rather one LingFeatures object.

Since a LingFeaturesSet object can be considered as an extended LingFeatures object, it is possible to match that as well.

For example, to express A noun and either feminine gender and nominate case, or masculine gender and gentive case the following WordPattern may be created:

  WordPattern pattern;

  WordPattern::GroupElement &rootElement =
    pattern.getModifiableRootElement();

  WordPattern::GroupElement &andGroup1 = rootElement.createAnd();

  WordPattern::LeafElement &nounLeaf = and1.createLeaf();
  nounLeaf.setPosDef(*nounDef); // The nounDef object is retrieved from
                                // some LingDef somewhere

  WordPattern::GroupElement &orGroup = andGroup1.createOr();

  WordPattern::GroupElement &andGroup2 = orGroup.createAnd();

  WordPattern::LeafElement &feminineLeaf = andGroup2.createLeaf();
  feminineLeaf.setFeature(*feminineDef);

  WordPattern::LeafElement &nominativeLeaf = andGroup2.createLeaf();
  nominativeLeaf.setFeature(*nominativeDef);

  WordPattern::GroupElement &andGroup3 = orGroup.createAnd();

  WordPattern::LeafElement &masculineLeaf = andGroup3.createLeaf();
  masculineLeaf.setFeature(*masculineDef);

  WordPattern::LeafElement &genitiveLeaf = andGroup3.createLeaf();
  genitiveLeaf.setFeature(*genitiveDef);
 

Sub classes of WordPatternFormatter may do this for you, using an external source of some sort.
