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.

Examples of org.mvel2.integration.VariableResolverFactory

            for (int i = 0; i < length; i++ ) {
                vars[i] = context.getVariable( unit.getOtherIdentifiers()[i] );
            }
        }


        VariableResolverFactory factory = unit.getFactory( context, null, null, null, vars, null, (GlobalResolver) context.getKnowledgeRuntime().getGlobals() );
        
        // do we have any functions for this namespace?
        KnowledgePackage pkg = context.getKnowledgeRuntime().getKnowledgeBase().getKnowledgePackage( "MAIN" );
        if ( pkg != null && pkg instanceof KnowledgePackageImp) {
            MVELDialectRuntimeData data = ( MVELDialectRuntimeData ) ((KnowledgePackageImp) pkg).pkg.getDialectRuntimeRegistry().getDialectData( id );
            factory.setNextFactory( data.getFunctionFactory() );
