public class MetadataPanel
extends JPanel

Extends JPanel providing a panel for displaying and editing document metadata. This is embedded as a tab in the EditorPanel.

Note: the implementation currently is not finished, in that the grouped metadata fields that are subclasses of AbstractMetaField (CreatorField and ContributorField) are not yet fully functional, and only support one value of each, ignoring any additional values.

Called when the reference list is double-clicked upon on index.

getBiblioCID

public String getBiblioCID()

Returns the ID of the current bibliographic reference Collection.

addReference

public void addReference(boolean isNewReference)

Add a bibliographic reference as a URI to this document.

This corresponds to Dublin Core Terms DCTERMS.references, previously Relation.References.

addToRefList

protected void addToRefList(URI uri)

Adds the URI to the bibliographic reference list.

This corresponds to Dublin Core Terms DCTERMS.references, previously Relation.References.

removeReference

public void removeReference()

Remove the selected bibliographic reference from this document.

This corresponds to Dublin Core Terms DCTERMS.references, previously Relation.References.

getReferences

public String getReferences()

Returns the DCTERMS.references (as XNode metadata properties) as a WS-delimited String of URIs, null if none are set.

This corresponds to Dublin Core Terms DCTERMS.references, previously Relation.References. Note that the 's' in the term name is an indication of an active verb, not a plural noun.

setReferences

protected void setReferences(String s)

Sets the DCTERMS.references (as XNode metadata properties) from the provided WS-delimited String.

This corresponds to Dublin Core Terms DCTERMS.references, previously Relation.References. Note that the 's' in the term name is an indication of an active verb, not a plural noun.

setXID

public void setXID(XNodeID xid,
                   boolean strict)
            throws ProcessException

Sets the content of the Collection and Node ID fields, checking to be sure that they are valid XML Names if strict is true. See the notes for setCID(String,boolean) and setNID(String,boolean) for details (this method calls them both).

Throws:

ProcessException - if strict is true and the provided Strings are not both XML Names.

setCID

public void setCID(String cid,
                   boolean strict)
            throws ProcessException

Sets the content of the Collection ID field, checking to be sure that it is a valid XML Name if strict is true. If the String cid is null and strict is false, the field is set to an empty string.

Throws:

ProcessException - if strict is true and the provided String is not an XML Name.

getCID

public String getCID()

This returns the content of the Collection ID field, which may not be harmonized with the current selection in the DocumentView's Collection list. Returns null if the field is empty or the current value is not an XML Name.

Sets the content of the Node ID field, checking to be sure that it is a valid XML Name if strict is true. If the String nid is null and strict is false, the field is set to an empty string.

Throws:

ProcessException - if strict is true and the provided String is not an XML Name.

getNID

public String getNID()

Returns the content of the Node ID field, checking to be sure that the result is a valid XML Name. If there is no selected node or the node name is invalid, returns null. Unlike getHarmonizedNid(), this does not harmonize the Node ID field with the Node list, and should only be used when the field value is desired (eg., when creating a new node).

Returns:

the content of the Node ID field.

getHarmonizedNid

public String getHarmonizedNid()
                        throws ProcessException

Harmonizes the value of the Node ID field with the Node ID list, then checks to be sure that the result is a valid XML Name. If there is no selected node or the node name is invalid, throws a ProcessException.

Returns:

the content of the Node ID field.

Throws:

ProcessException - if strict is true and the content is not an XML Name.

queryNodeId

public String queryNodeId(String cid,
                          String nid)

Returns a valid Node ID value by querying the user with a dialog box, using the provided String nid as the default. This method is identical to queryNodeId(String,String) except the Collection ID is read-only.

queryNodeId

public String[] queryNodeId(String cid,
                            String nid,
                            boolean canSelectCID)

Returns valid Collection and Node ID values by querying the user with a dialog box, using the provided String nid as the default. The Collection ID is provided for user context, and is editable when canSelectCID is true. If the Collection ID is not provided, the value from the current MetadataPanel will be used. Returns null if the user cancels or does not provide a valid ID value (an XML Name). The Collection ID is array index 0, the Node ID index 1.

setTitle

public void setTitle(String title)

Sets the title for the currently-displayed document to the String title. This is the "metadata" title of the document, not its system id. If title is null, the field is cleared. This is protected, as it should be set by its parent view, not directly.

getTitle

public String getTitle()

Returns the title of the currently-displayed document as a String. This will be whitespace-trimmed.
