Constructor Detail

LocationsTagger

public LocationsTagger()

LocationsTagger

public LocationsTagger(int mincnt)

Construct a new tagger.

Parameters:

mincnt - the minimal count of the location names detected in the area necessary for tagging this area.

Method Detail

getId

public String getId()

getName

public String getName()

getDescription

public String getDescription()

getParamNames

public String[] getParamNames()

Specified by:

getParamNames in interface org.fit.layout.api.ParametrizedOperation

Overrides:

getParamNames in class BaseTagger

getParamTypes

public org.fit.layout.api.ParametrizedOperation.ValueType[] getParamTypes()

Specified by:

getParamTypes in interface org.fit.layout.api.ParametrizedOperation

Overrides:

getParamTypes in class BaseTagger

getMincnt

public int getMincnt()

setMincnt

public void setMincnt(int mincnt)

getTag

public TextTag getTag()

Description copied from interface: Tagger

Obtains the tag that this tagger assigns to the areas.

Returns:

the tag string

belongsTo

public float belongsTo(org.fit.layout.model.Area node)

Description copied from interface: Tagger

Checks whether the area may be tagged with the tag. This method does not actually assign the tag to the area.

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.

Parameters:

src - The source string.

Returns:

A list of extracted strings.

split

public List<String> split(String src)

Description copied from interface: Tagger

Splits the string to substrings where each substring either corresponds to this tag or it does not correspond.

Parameters:

src - The source string.

Returns:

A list of strings; the contcatentation of the strings should put src back.
