public interface LabelFactory
LabelFactory object acts as a factory for creating
objects of class Label, or some descendant class.
It can also make Labels from Strings, optionally with options.| Modifier and Type | Method and Description |
|---|---|
Label |
newLabel(Label oldLabel)
Create a new
Label, where the label is formed from
the Label object passed in. |
Label |
newLabel(java.lang.String labelStr)
Make a new label with this
String as the
value. |
Label |
newLabel(java.lang.String labelStr,
int options)
Make a new label with this
String as the value, and
the type determined in an implementation-dependent way from the
options value. |
Label |
newLabelFromString(java.lang.String encodedLabelStr)
Make a new label.
|
Label newLabel(java.lang.String labelStr)
String as the
value.
Any other fields of the label would normally be null.labelStr - The String that will be used for valueLabel newLabel(java.lang.String labelStr, int options)
String as the value, and
the type determined in an implementation-dependent way from the
options value.labelStr - The String that will be used for valueoptions - May determine what kind of label is createdLabel newLabelFromString(java.lang.String encodedLabelStr)
encodedLabelStr - The String that will be used for labelling the
object (by decoding it into parts)Label newLabel(Label oldLabel)
Label, where the label is formed from
the Label object passed in. The new Label is
guaranteed to at least copy the value() of the
source label (if non-null); it may also copy other components
(this is implementation-specific). However, if oldLabel is of
the same type as is produced by the factory, then the whole
label should be cloned, so that the returnedLabel.equals(oldLabel).
Implementation note: That last sentence isn't true of all
current implementations (e.g., WordTag), but we should make it
so that it is true!oldLabel - The Label that the new label is being created from
