DefaultGraph (yFiles-for-JavaFX-Complete-3.0 API)

java.lang.Object
- com.yworks.yfiles.graph.DefaultGraph

All Implemented Interfaces:

IGraph, ILookup, ITagOwner
```
public class DefaultGraph
extends Object
implements IGraph
```
Central implementation of the IGraph interface.
This implementation deals with the proper firing of events and handling of default values.
This implementation has inherent support for undoability. If the UndoEngineEnabled property is set to true, changes to the structure of the graph will automatically be recorded using the UndoEngine instance that can be queried from this instance's lookup(Class) method. Clients that wish to enqueue custom undo events or that need to make non-structural changes to the graph can use the UndoEngine to do so. The current instance of UndoEngine can be queried using the ILookup.lookup(Class) method of this instance. Also there are several protected methods Create...UndoUnit that will be used by this instance to create the actual undo units for structural changes in the graph's structure. If clients need to customize these units they can create a subclass of DefaultGraph and override these methods.
Finally this implementation supports grouped graphs.

DefaultGraph is IGraph's default implementation as described in the section The Graph Model - IGraph.

In those cases it is recommended to store the nodes in your own list, if possible. This is not necessary for the first or last element or when iterating over the nodes via a foreach loop.
    
    Specified by:
    
    getNodes in interface IGraph
    
    Returns:
    
    The Nodes.

  - getPorts
```
public final IListEnumerable<IPort> getPorts()
```
    Description copied from interface: IGraph
    
    A view of the ports contained in this graph.
    This is a live view of the ports that always represents the current state of the graph. The same reference will be returned for each invocation.
    
    Note that even though ports can be accessed via index, the underlying graph structure in the default IGraph implementation is a linked list and indexed access can be slow. In those cases it is recommended to store the ports in your own list, if possible. This is not necessary for the first or last element or when iterating over the ports via a foreach loop.
    
    Specified by:
    
    getPorts in interface IGraph
    
    Returns:
    
    The Ports.
  - getTag
```
public final Object getTag()
```
    Description copied from interface: ITagOwner

    Specified by:
    
    getTag in interface ITagOwner
    
    Returns:
    
    The user object associated with this instance.

    Clients can call this method to force an invalidation of the displays that show this graph instance. This implementation delegates to onInvalidateDisplays(IEventArgs).
    
    Specified by:
    
    invalidateDisplays in interface IGraph
  - isGroupNode
```
public final boolean isGroupNode(INode node)
```
    Description copied from interface: IGraph
    
    Returns whether the given node is considered a group node.
    Group nodes may have children but do not necessarily need to have children.
    
    Specified by:
    
    isGroupNode in interface IGraph
    
    Parameters:
    
    node - The node to check.
    
    Returns:
    
    Whether the node is considered a group node.

  - isUndoEngineEnabled
```
public boolean isUndoEngineEnabled()
```

    Specified by:
    
    isUndoEngineEnabled in interface IGraph
    
    Returns:
    
    The UndoEngineEnabled.
    
    See Also:
    
    setUndoEngineEnabled(boolean)
  - lookup
```
public <TLookup> TLookup lookup(Class<TLookup> type)
```
    Returns an instance that provides another aspect of this instance of the given type or null.
    Typically, this method will be called in order to obtain a different view or aspect of the current instance. This is quite similar to casting or using a super type or interface of this instance, but is not limited to inheritance or compile time constraints. This method is not required to return non-null implementations for the types, nor does it have to return the same instance any time. Also it depends on the type and context whether the instance returned stays up to date or needs to be re-obtained for subsequent use. This implementation uses the set lookup implementation if it has been set or an internal lookup chain, that can be customized using the addLookup(IContextLookupChainLink) and removeLookup(IContextLookupChainLink) methods.
    
    Specified by:
    
    lookup in interface ILookup
    
    Parameters:
    
    type - the type for which an instance shall be returned
    
    Returns:
    
    An instance that is assignable to type or null

public void remove(IModelItem item)
```
    Description copied from interface: IGraph
    
    Removes the given item from this graph.
    The item must be a part of this graph.
    
    If the item is a node the NodeRemoved event will be triggered. The implementation will remove all adjacent edges and their corresponding ports in proper order before the node will be removed. Also this will trigger the removal of all labels owned by this instance.
    
    If the item is an edge the EdgeRemoved event will be triggered. The implementation may decide to remove the corresponding ports from the node if no other edge connects to them after the given edge has been removed. Also this will trigger the removal of all labels and bends owned by this instance.
    
    If the item is a bend the BendRemoved event will be triggered.
    
    If the item is a port the PortRemoved event will be triggered. This will also remove all edges that are currently connected to the port.
    
    If the item is a label the LabelRemoved event will be triggered.

    Description copied from interface: IGraph
    
    Removes the given listener for the PortTagChanged event that occurs when the tag of a port has been replaced.
    This event is intended to provide notification of low level changes in the graph structure. Note:You may not modify the graph in the event handler for this event.
    
    Specified by:
    
    removePortTagChangedListener in interface IGraph
    
    Parameters:
    
    portTagChangedEvent - The listener to remove.

public void setBendLocation(IBend bend,
                            PointD location)
```
    Modifies the location of the given bend.
    This implementation will also trigger an invalidateDisplays() call.
    
    Specified by:
    
    setBendLocation in interface IGraph
    
    Parameters:
    
    bend - the bend whose location is to be modified

  - setEdgeDefaults
```
public final void setEdgeDefaults(IEdgeDefaults value)
```
    Description copied from interface: IGraph
    
    Sets the defaults for normal edges.
    The settings that are obtained from the instance influence newly created elements only. Setting different defaults afterwards does not influence existing elements.
    
    Specified by:
    
    setEdgeDefaults in interface IGraph
    
    Parameters:
    
    value - The EdgeDefaults to set.

                         IPort targetPort)
```
    Sets the ports of the given edge to the new values.
    This will trigger an EdgePortsChanged event if source or target ports differ from the current ones. Both ports and the edge must belong to the current graph instance. If AutoCleanupEnabled is enabled, this method will remove unoccupied ports after they have been changed.
    
    Specified by:
    
    setEdgePorts in interface IGraph
    
    Parameters:
    
    edge - The edge to change the ports.
