Examples of VariableResolverFactory

org.mvel2.integration.VariableResolverFactory
A VariableResolverFactory is the primary integration point for tying in external variables. The factory is responsible for returing {@link org.mvel2.integration.VariableResolver}'s to the MVEL runtime. Factories are also structured in a chain to maintain locality-of-reference.
