Constructor Detail

TaggedWordFactory

public TaggedWordFactory()

Create a new TaggedWordFactory. The divider will be taken as '/'.

TaggedWordFactory

public TaggedWordFactory(char divider)

Create a new TaggedWordFactory.

Parameters:

divider - This character will be used in calls to the one argument version of newLabel(), to divide the word from the tag. Stuff after the last instance of this character will become the tag, and stuff before it will become the label.

Method Detail

newLabel

public Label newLabel(String labelStr)

Make a new label with this String as the value (word). Any other fields of the label would normally be null.

Specified by:

newLabel in interface LabelFactory

Parameters:

labelStr - The String that will be used for value

Returns:

The new TaggedWord (tag will be null)

newLabel

public Label newLabel(String labelStr,
                      int options)

Make a new label with this String as a value component. Any other fields of the label would normally be null.

Specified by:

newLabel in interface LabelFactory

Parameters:

labelStr - The String that will be used for value

options - what to make (use labelStr as word or tag)

Returns:

The new TaggedWord (tag or word will be null)

newLabelFromString

public Label newLabelFromString(String word)

Create a new word, where the label is formed from the String passed in. The String is divided according to the divider character. We assume that we can always just divide on the rightmost divider character, rather than trying to parse up escape sequences. If the divider character isn't found in the word, then the whole string becomes the word, and the tag is null.

Specified by:

newLabelFromString in interface LabelFactory

Parameters:

word - The word that will go into the Word

Returns:

The new TaggedWord

newLabel

public Label newLabel(Label oldLabel)

Create a new TaggedWord Label, where the label is formed from the Label object passed in. Depending on what fields each label has, other things will be null.

Specified by:

newLabel in interface LabelFactory

Parameters:

oldLabel - The Label that the new label is being created from

Returns:

a new label of a particular type
