Method Detail

isRoot

public boolean isRoot()

Returns:

true if model root has been removed

getModel

@NotNull
public SModel getModel()

Specified by:

getModel in class AbstractModelChangeEvent

Returns:

affected model

getParent

@Nullable
public SNode getParent()

Returns:

modified node, the one that lost child, or null for root remove event.

getChild

@NotNull
public SNode getChild()

Returns:

removed node. Beware, it's detached from the model and has limited functionality. E.g. SNode.getReference() doesn't make sense, use getModel().getReference() and SNode.getNodeId() instead.

getAggregationLink

@Nullable
public SContainmentLink getAggregationLink()
