Field Detail

LABEL_SIZE

private static final java.awt.Dimension LABEL_SIZE

The default size for a label.

---

library

private java.util.ArrayList library

A list of known, but currently unassigned, classifiers.

---

controls

private Control controls

The controls for editing the contents of this manager.

---

model

private DOMProxyListModel model

Constructor Detail

ClassifierManager

public ClassifierManager()

Constructor.

Method Detail

addClassifier

public void addClassifier(Classifier classifier)

Method to add a new classifier to library.

---

assignClassifier

public void assignClassifier(Classifier classifier)

Method to assign a classifier.

---

destroy

public void destroy()

Destructor.

---

getBaseClassifier

public Classifier getBaseClassifier(java.lang.String name)

---

getClassifier

public Classifier getClassifier(int index)

Method to retrieve the classifier with the given index.

---

getControls

public Control getControls()

Method to retrieve the control for this manager.

---

getHierarchyClassifiers

public java.util.ArrayList getHierarchyClassifiers()

---

isPhindClassifierAssigned

public boolean isPhindClassifierAssigned()

Determine if the Phind classifier has been assigned.

---

moveClassifier

public void moveClassifier(Classifier classifier,
                           boolean direction,
                           boolean all)

Method to move a classifier in the list order.

---

removeClassifier

public void removeClassifier(Classifier classifier)

This method removes an assigned classifier. I was tempted to call it unassign, but remove is more consistant. Note that there is no way to remove a classifier from the library.

---

saveClassifiers

public void saveClassifiers()

Method to cache the current contents of library (known classifiers) to file.

---

getAvailable

private java.lang.Object[] getAvailable()

---

getClassifierName

private java.lang.String getClassifierName(java.io.File classifier)

Method to extract just the classifiers name from a file object.

---

loadClassifier

private void loadClassifier(java.io.File classifier)

Method to load the details of a single plug-in.

---

loadClassifiers

private void loadClassifiers()

Method to initially load information from the standard plug-ins within the gsdl Perl library.

---

parseXML

private Classifier parseXML(org.w3c.dom.Node root)

Parses a DOM tree model turning it into a Classifier and its associated arguments.
