      Modifier and Type Method Description
      java.util.Map getAttributes()
      Returns a map that contains (object, map) pairs which holds the new attributes for each changed cell.
      java.lang.Object[] getChanged()
      Returns the cells that have changed.
      java.lang.Object[] getContext()
      Returns the objects that have not changed explicitly, but implicitly because one of their dependent cells has changed.
      java.awt.geom.Rectangle2D getDirtyRegion()
      Returns the dirty region for the original position of the changed cells before the change happened.
      java.lang.Object[] getInserted()
      Returns the cells that have been inserted.
      java.util.Map getPreviousAttributes()
      Returns a map that contains (object, map) pairs which holds the previous attributes for the changed cells.
      java.lang.Object[] getRemoved()
      Returns the cells that have been removed.
      java.lang.Object getSource()
      Returns the source of this change.
      void setDirtyRegion​(java.awt.geom.Rectangle2D dirty)
      In some cases the class firing this event will not have access to the dirty region prior to the change.
    • Method Detail

      • getSource

        java.lang.Object getSource()
        Returns the source of this change. This can either be a view or a model, if this change is a GraphModelChange. Note: This is not necessarily the same as the source of the event and is used separately in the graphundomanager.
        Returns:
        the source fo this change
      • getChanged

        java.lang.Object[] getChanged()
        Returns the cells that have changed.
        Returns:
        the cell changed
      • getInserted

        java.lang.Object[] getInserted()
        Returns the cells that have been inserted.
        Returns:
        the cells that were inserted by the change
      • getRemoved

        java.lang.Object[] getRemoved()
        Returns the cells that have been removed.
        Returns:
        the cells that were removed by the change
      • getAttributes

        java.util.Map getAttributes()
        Returns a map that contains (object, map) pairs which holds the new attributes for each changed cell. Note: This returns a map of (cell, map) pairs for an insert on a model that is not an attribute store. Use getPreviousAttributes to access the attributes that have been stored in the model.
      • getPreviousAttributes

        java.util.Map getPreviousAttributes()
        Returns a map that contains (object, map) pairs which holds the previous attributes for the changed cells.
        Returns:
        map of attributes before the change
      • getDirtyRegion

        java.awt.geom.Rectangle2D getDirtyRegion()
        Returns the dirty region for the original position of the changed cells before the change happened.
        Returns:
        the dirty region prior to the event
      • setDirtyRegion

        void setDirtyRegion​(java.awt.geom.Rectangle2D dirty)
        In some cases the class firing this event will not have access to the dirty region prior to the change. It is then up to the receiving class to set it once.
        Parameters:
        dirty -
      • getContext

        java.lang.Object[] getContext()
        Returns the objects that have not changed explicitly, but implicitly because one of their dependent cells has changed. This is typically used to return the edges that are attached to vertices, which in turn have been resized or moved.
        Returns:
        array of contextual cells
