Method Detail

createSettings

protected com.jgraph.editor.JGraphEditorSettings createSettings(java.util.Map args)

Constructs the editor settings. This implementation constructs a new instance of JGraphEditorSettings using args as the initial object map and passes it to the #configureSettings(JGraphEditorSettings)method.

Parameters:

args - The arguments passed to the command line.

Returns:

Returns a configured editor settings object.

configureModel

protected void configureModel(com.jgraph.editor.JGraphEditorModel model)

Hook for subclassers to configure new document models. This implementation adds persistence delegates for the following classes: JGraphpadDiagram,JGraphpadGraphModel, com.jgraph.graph.ConnectionSet, JGraphpadGraphLayoutCache, com.jgraph.graph.DefaultGraphCell, com.jgraph.graph.DefaultEdge, com.jgraph.graph.DefaultPort,JGraphpadBusinessObject, JGraphpadRichTextValueand JGraphpadShadowBorder.
JGraphpadDiagram
Constructs a persistence delegate for the diagram class. This uses the fact that all information is stored in the model, not the layout cache by ignoring the layout cache and accessing the model stored in the layout cache directly through the model bean property. Note: To allow this kind of encoding the diagram class offers a special constructor that takes a model and constructs a new graph layout cache for it.
JGraphpadGraphModel
To encode graph models we do not want the files to contain redundant connectivity information in the ports.edges and edges.source and target fields, so we add a method to the graph model that returns a connection set which describes the connections without redundancy. (Note: In the static initializer of this class we make sure that the edges, source and target of the respective classes or not encoded.)
ConnectionSet
The complete information of a connection set is stored in the actual connections, thus we only store the connections and use special constructor to restore the state of the complete object when de- coding. (Note: For connection sets this will update the edges field.)
JGraphpadGraphLayoutCache
The graph layout cache is encoded by encoding the various member fields, using a special constructor to restore the state of the layout cache upon decoding. Note that this is currently not used.
DefaultGraphCell, DefaultEdge, DefaultPort
Makes sure the cells are only encoded along with their user objects, the attributes, connections and tree-structure is stored in other objects and does not need to be encoded here.
JGraphpadBusinessObject, JGraphpadRichTextData
Allows to encode custom business objects used in JGraphpad. Since this object implements the bean interface we do only require a default persistence delegates with no special constructor calls to decode the object. Same holds for the rich text data object, which is a special value that can hold text formatting information.
JGraphShadowBorder
Since the shadow border is a singleton we must tell the decoder which method to use in order to find the shared instance of the class.

Parameters:

model - The document model to be configured.

configureKit

Returns a new DefaultGraphCell containing the specified user object. This implementation uses createAttributeMap()to create the map that holds the attributes for the new vertex, and configureVertex(GraphCell)to configure the vertex.

Parameters:

userObj - The user object that the vertex should contain.

Returns:

Returns a new vertex.

configureVertex

protected void configureVertex(org.jgraph.graph.GraphCell vertex)

Hook for subclassers to configure the specified vertex. This implementation sets the defaultBorderColorand adds ports if the vertex implements the MutableTreeNodeinterface.

Parameters:

vertex - The vertex to be configured.

addPorts(MutableTreeNode, Point2D[])

createGroup

public org.jgraph.graph.GraphCell createGroup()

Hook for subclassers to construct groups with default user objects. This implementation invokes createVertexUserObject(Object)and passes the return value to createGroup(Object).

Returns:

Returns a new group with a default user object.

createGroup

public org.jgraph.graph.GraphCell createGroup(java.lang.Object userObj)

Returns a new DefaultGraphCell containing the specified user object. This implementation uses createAttributeMap()to create the map that holds the attributes for the new vertex, and configureVertex(GraphCell)to configure the vertex.

Parameters:

userObj - The user object that the group should contain.

Returns:

Returns a new group.

addPorts

protected void addPorts(javax.swing.tree.MutableTreeNode parent,
                        java.awt.geom.Point2D[] offsets)

Adds ports to parent using offsets as the port relative offsets. The method uses createPortUserObject(Object), createPort(MutableTreeNode, Object)and configurePort(GraphCell, Point2D)to create the ports and their user objects, configure them and add them to the parent.

Parameters:

parent - The parent to add the ports to.

offsets - The points defining the port locations.

createPort

public org.jgraph.graph.GraphCell createPort(javax.swing.tree.MutableTreeNode parent,
                                             java.lang.Object userObject)

Creates a port containing the specified user object and adds it to parent.

Parameters:

userObject - The user object that the port should contain.

Returns:

Returns a new port.

configurePort

public void configurePort(org.jgraph.graph.GraphCell port,
                          java.awt.geom.Point2D offset)

Hook for subclassers to configure the specified port using the offset as the relative location.

Parameters:

port - The port to be configured.

offset - The relative offset of the port.

createEdge

public org.jgraph.graph.DefaultEdge createEdge()

Hook for subclassers to construct edgges with default user objects. This implementation invokes createEdgeUserObject(Object)and passes the return value to createEdge(Object).

Returns:

Returns a new edge with a default user object.

createEdge

public org.jgraph.graph.DefaultEdge createEdge(java.lang.Object userObj)

Returns a new DefaultEdge containing the specified user object. This implementation uses createAttributeMap()to create the map that holds the attributes for the new edge and configureEdge(GraphCell)to configure the edge.

Parameters:

userObj - The user object that the edge should contain.

Returns:

Returns a new edge.

configureEdge

protected void configureEdge(org.jgraph.graph.GraphCell edge)

Hook for subclassers to configure the specified edge. This implementation sets the defaultEdgeFont,defaultEndDecorationand defaultBeginDecoration.

Parameters:

edge - The edge to be configured.

createEdgeUserObject

protected java.lang.Object createEdgeUserObject(java.lang.Object value)

Hook for subclassers to create a user object for edges that contains the specified value. This implementation calls createVertexUserObject(Object).

Parameters:

value - The value that the user object should contain.

Returns:

Returns a new user object containing value.

createPortUserObject

protected java.lang.Object createPortUserObject(java.lang.Object value)

Hook for subclassers to create a user object for ports that contains the specified value. This implementation calls createVertexUserObject(Object).

Parameters:

value - The value that the user object should contain.

Returns:

Returns a new user object containing value.
