Constructor Detail

MapLabel

public MapLabel()

Create a new MapLabel with null value.

MapLabel

public MapLabel(String value)

Create a new MapLabel with the given value.

Parameters:

value - the value of the new label

MapLabel

public MapLabel(Label label)

Create a new MapLabel with the value of another Label as its value.

If the argument label is a MapLabel, the new label is identical to the argument label (but does not share storage). If the argument is a MapLabel, it just copies the map, but doesn't make copies of the map's contents.

If the argument label implements HasWord and/or HasTag, such as a CategoryWordTag, the category, word, and tag are stored in the map of the new label under the map keys CATEGORY_KEY, WORD_KEY, and TAG_KEY, respectively.

Parameters:

label - the other label

Method Detail

labelFactory

public LabelFactory labelFactory()

Return a factory for MapLabels. The factory returned is always the same one (a singleton).

Returns:

the label factory

factory

public static LabelFactory factory()

Return a factory for MapLabels. The factory returned is always the same one (a singleton).

Returns:

the label factory

toString

public String toString()

Return a String containing the value (and index, if any) of this label. This is equivalent to toString("value-index").

Specified by:

toString in interface Label

Overrides:

toString in class Object

Returns:

a text representation of the full label contents

toString

public String toString(String format)

Returns a formatted string representing this label. The desired format is passed in as a String. Currently supported formats include:

• "value": just prints the value
• "{map}": prints the complete map
• "value{map}": prints the value followed by the contained map (less the map entry containing key CATEGORY_KEY)
• "value-index": extracts a value and an integer index from the contained map using keys INDEX_KEY, respectively, and prints them with a hyphen in between
• "value-index{map}": a combination of the above; the index is displayed first and then not shown in the map that is displayed
• "word": Just the value of HEAD_WORD_KEY in the map

Map is printed in alphabetical order of keys.

setPrintOptions

public static void setPrintOptions(String po)

main

public static void main(String[] args)

For testing only.
