Constructor Detail

CategoryWordTag

public CategoryWordTag()

CategoryWordTag

public CategoryWordTag(java.lang.String label)

This one argument constructor sets just the value.

Parameters:

label - the string that will become the category/value

CategoryWordTag

public CategoryWordTag(java.lang.String category,
                       java.lang.String word,
                       java.lang.String tag)

CategoryWordTag

public CategoryWordTag(Label oldLabel)

Creates a new CategoryWordTag label from an existing label. The oldLabel value() -- i.e., category -- is used for the new label. The tag and word are initialized iff the current label implements HasTag and HasWord respectively.

Parameters:

oldLabel - The label to use as a basis of this Label

Method Detail

category

public java.lang.String category()

Description copied from interface: HasCategory

Return the category value of the label (or null if none).

Specified by:

category in interface HasCategory

Returns:

String the category value for the label

setCategory

public void setCategory(java.lang.String category)

Description copied from interface: HasCategory

Set the category value for the label (if one is stored).

Specified by:

setCategory in interface HasCategory

Parameters:

category - The category value for the label

word

public java.lang.String word()

Description copied from interface: HasWord

Return the word value of the label (or null if none).

Specified by:

word in interface HasWord

Returns:

String the word value for the label

setWord

public void setWord(java.lang.String word)

Description copied from interface: HasWord

Set the word value for the label (if one is stored).

Specified by:

setWord in interface HasWord

Parameters:

word - The word value for the label

tag

public java.lang.String tag()

Description copied from interface: HasTag

Return the tag value of the label (or null if none).

Specified by:

tag in interface HasTag

Returns:

String the tag value for the label

setTag

public void setTag(java.lang.String tag)

Description copied from interface: HasTag

Set the tag value for the label (if one is stored).

Specified by:

setTag in interface HasTag

Parameters:

tag - The tag value for the label

setCategoryWordTag

public void setCategoryWordTag(java.lang.String category,
                               java.lang.String word,
                               java.lang.String tag)

toString

public java.lang.String toString()

Returns a String representation of the label. This attempts to be somewhat clever in choosing to print or suppress null components and the details of words or categories depending on the setting of printWordTag and suppressTerminalDetails.

Specified by:

toString in interface Label

Overrides:

toString in class StringLabel

Returns:

The label as a string

toString

public java.lang.String toString(java.lang.String mode)

Returns a String representation of the label. If the argument String is "full" then all components of the label are returned, and otherwise the normal toString() is returned.

Returns:

The label as a string

setFromString

public void setFromString(java.lang.String labelStr)

Set everything by reversing a toString operation. This should be added at some point.

Specified by:

setFromString in interface Label

Overrides:

setFromString in class StringLabel

Parameters:

labelStr - The str for the label

labelFactory

public LabelFactory labelFactory()

Return a factory for this kind of label (i.e., CategoryWordTag). The factory returned is always the same one (a singleton).

Specified by:

labelFactory in interface Label

Overrides:

labelFactory in class StringLabel

Returns:

The label factory

factory

public static LabelFactory factory()

Return a factory for this kind of label

Returns:

The label factory
