public class ValueManager
extends JPanel

Extends JPanel as a container for ValuePanel instances, selectable via a String identifier (generally a URI indicating a datatype). Creation of the ValueManager will automatically create an instance of the DatatypeValuePanel used to select from among the available datatypes. This is in addition to the optionally-provided default ValuePanel (generally, a StringValuePanel).

Note that currently, datatype registrations simply overwrite any previous registration on duplications. (This should probably throw an exception.)

Field Detail

protected boolean m_editable

Constructor Detail

ValueManager

public ValueManager(JPanel parent,
                    ValuePanel defaultPanel)

Constructor for a ValueManager. If the optional ValuePanel defaultPanel is included, adds it to the CardLayout, using it as a the default datatype input panel rather than throwing NullPointerExceptions when called upon to perform operations with no available ValuePanels.

Parameters:

defaultPanel - optionally adds as default ValuePanel

Method Detail

setEditable

public void setEditable(boolean editable)

Sets the editable state of this ValueManager and any currently-stored ValuePanels.

isEditable

public boolean isEditable()

Returns true if the current ValuePanel is editable.

showType

public void showType(String identifier)

Sets the displayed datatype using the identifier identifier for a specific ValuePanel. The 'String' datatype is default, and displayed when the parameter is null. If no StringValuePanel is available, all hell breaks loose.

addValuePanel

public void addValuePanel(ValuePanel vp)

Adds the ValuePanel to this ValueManager.

removeValuePanel

public void removeValuePanel(ValuePanel vp)

Removes the ValuePanel from this ValueManager. If the panel was not a member of the layout, nothing happens.

getID

public final String getID()

Returns the datatype identifier of the current ValuePanel. If there are no ValuePanels in storage, returns null.

clear

public void clear()

Clears the value of the current ValuePanel's content.

setValue

public void setValue(Object value)

Sets the value of this ValueManager's content. If there are no ValuePanels in storage the default panel will be used.

getValue

public String getValue()

Returns the value of this ValueManager's content as a String.
