getDescription

public String getDescription()

getTag

public TextTag getTag()

Description copied from interface: Tagger

Obtains the tag that this tagger assigns to the areas.

Parameters:

node - The examined area node.

Returns:

the relevance of the assignment (0.0 = not assigned, 0.1 = hopefully possible, >0.5 quite possible, 1.0 absolutely sure)

allowsContinuation

public boolean allowsContinuation(org.fit.layout.model.Area node)

Description copied from interface: Tagger

Checks whether the area may be a continuation of a previously started area tagged with this tag.

Parameters:

node - The examined area node.

Returns:

true if the area may be a continuation of a tagged area

allowsJoining

public boolean allowsJoining()

Description copied from interface: Tagger

Checks whether the tag may be used for joining the areas in the visual area tree.

Returns:

true if the tag may be used for joining.

mayCoexistWith

public boolean mayCoexistWith(org.fit.layout.model.Tag other)

Description copied from interface: Tagger

Check if the area tagged with this tag may be tagged with another tag. If not, this tag won't be used for the areas already tagged with another tag.

extract

public List<String> extract(String src)

Description copied from interface: Tagger

Extracts the parts of a source string that correspond to this tag.
