Method Detail

addTagger

public void addTagger(Tagger tagger)

getAllTags

public List<org.fit.layout.model.Tag> getAllTags()

Obtains the list of all tags used by the taggers

Returns:

the list of tags

tagTree

public void tagTree()

Applies all the taggers to the whole tree.

tagSubtree

public void tagSubtree(org.fit.layout.model.Area root)

Applies all the taggers a subtree of the area tree.

Parameters:

root - the root node of the subtree

tagSingleNode

public void tagSingleNode(org.fit.layout.model.Area area)

Applies all the taggers to a single tree node.

Parameters:

area - the tree node

getSharedClassifier

public static edu.stanford.nlp.ie.AbstractSequenceClassifier<?> getSharedClassifier()

Checks if two logical nodes are joinable. For this, the must

• Made of neighboring area nodes (nothing between them)
• Have the same style
• Have the same tags or the second one may be a continuation of the first one
• None of the tags of the second node may refuse joining

Parameters:

l1 - the first logical node

l2 - the second logical node

Returns:

true if the nodes may be joined
