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

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

All Implemented Interfaces:

IGraph, ILookup, ITagOwner, IDisposable, AutoCloseable

Direct Known Subclasses:

FilteredGraphWrapper
```
public abstract class AbstractGraphWrapper
extends Object
implements IGraph, IDisposable
```
An abstract IGraph implementation that delegates all of its work to an existing implementation.
Subclasses can override all of the methods to customize the behavior of this instance. Note that this instance will register listeners with the wrapped graph instance, so dispose() should be called if this instance is not used any more.

An instance implementing 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 reobtained for subsequent use.

    Parameters:
    
    type - the type for which an instance shall be returned

```
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.
    
    Specified by:
    
    remove in interface IGraph
    
    Parameters:
    
    item - the live item to be removed from this graph instance
