TGGraphNodesEnumerator.CurrentElement Method

Scroll Prev Top Next More

Returns the current node in the enumeration, your "place" in the enumeration.

When the iterator is first supplied or when it is Reset , there is no current element (calling this method in such a case should raise an exception). Only after the first call to the NextElement method will this method return a value.

Unlike the GGraph.TGGraphNodesEnumerator.NextElement method which returns a new node every time you call it, this method always returns the same value no matter how many times you call it (until NextElement is called, of course).

Namespace: GGraph

Return Value

Type: TObject
