Examples of BindingsCollection

lupos.datastructures.bindings.BindingsCollection
Instances of this class store bindings in collections.
A binding is an association between a variable and an actual value called literal.
In this collection, the variables and literals are stored in two different sorted collections and can be associated by their indexes in each collection: a variable at position 'i' in the variables' collection is associated to the literal at position 'i' in the literals' collection @author Sebastian Ebers
