        Validates and possibly edits the given subtree by diffing and recursing through it.
        Parameters:
        editor - editor for the root of the subtree
        before - state of the original subtree
        after - state of the modified subtree
        Returns:
        exception if the processing failed, null otherwise
      • propertyAdded

        public boolean propertyAdded​(PropertyState after)
        Description copied from interface: NodeStateDiff
        Called for all added properties.
        Specified by:
        propertyAdded in interface NodeStateDiff
        Parameters:
        after - property state after the change
        Returns:
        true to continue the comparison, false to abort. Abort will stop comparing completely, that means sibling nodes and sibling nodes of all parents are not further compared.
      • propertyChanged

        public boolean propertyChanged​(PropertyState before,
                                       PropertyState after)
        Description copied from interface: NodeStateDiff
        Called for all changed properties. The names of the given two property states are guaranteed to be the same.
        Specified by:
        propertyChanged in interface NodeStateDiff
        Parameters:
        before - property state before the change
        after - property state after the change
        Returns:
        true to continue the comparison, false to abort. Abort will stop comparing completely, that means sibling nodes and sibling nodes of all parents are not further compared.
      • propertyDeleted

        public boolean propertyDeleted​(PropertyState before)
        Description copied from interface: NodeStateDiff
        Called for all deleted properties.
        Specified by:
        propertyDeleted in interface NodeStateDiff
        Parameters:
        before - property state before the change
        Returns:
        true to continue the comparison, false to abort. Abort will stop comparing completely, that means sibling nodes and sibling nodes of all parents are not further compared.
      • childNodeAdded

        public boolean childNodeAdded​(java.lang.String name,
                                      NodeState after)
        Description copied from interface: NodeStateDiff
        Called for all added child nodes.
        Specified by:
        childNodeAdded in interface NodeStateDiff
        Parameters:
        name - name of the added child node
        after - child node state after the change
        Returns:
        true to continue the comparison, false to abort. Abort will stop comparing completely, that means sibling nodes and sibling nodes of all parents are not further compared.
      • childNodeChanged

        public boolean childNodeChanged​(java.lang.String name,
                                        NodeState before,
                                        NodeState after)
        Description copied from interface: NodeStateDiff
        Called for all child nodes that may contain changes between the before and after states. The comparison implementation is expected to make an effort to avoid calling this method on child nodes under which nothing has changed.
        Specified by:
        childNodeChanged in interface NodeStateDiff
        Parameters:
        name - name of the changed child node
        before - child node state before the change
        after - child node state after the change
        Returns:
        true to continue the comparison, false to abort. Abort will stop comparing completely, that means sibling nodes and sibling nodes of all parents are not further compared.
      • childNodeDeleted

        public boolean childNodeDeleted​(java.lang.String name,
                                        NodeState before)
        Description copied from interface: NodeStateDiff
        Called for all deleted child nodes.
        Specified by:
        childNodeDeleted in interface NodeStateDiff
        Parameters:
        name - name of the deleted child node
        before - child node state before the change
        Returns:
        true to continue the comparison, false to abort. Abort will stop comparing completely, that means sibling nodes and sibling nodes of all parents are not further compared.
