                                                                                                                                                                              GraphStrategy strategyComposer)

Description copied from interface: GraphStrategy

Construct a Function that enhances the features of Element.Iterators.propertyIterator(java.lang.String...).

Specified by:

getVertexIteratorsPropertyIteratorStrategy in interface GraphStrategy

Parameters:

ctx - the context within which this strategy function is called

strategyComposer - the strategy that composed this strategy function

Returns:

a Function that accepts a Function with Element.Iterators.propertyIterator(java.lang.String...) signature and returns an enhanced strategy Supplier with the same signature
