Examples of PlugInAggregationMultiFunctionDeclarationContext

com.espertech.esper.plugin.PlugInAggregationMultiFunctionDeclarationContext
Context for use with {@link PlugInAggregationMultiFunctionFactory} providesinformation about an aggregation function at the time of declaration.
Declaration means when the aggregation function is discovered at the time of parsing an EPL statement. Or when using statement object model then at the time of mapping the object model to the internal statement representation.

            PlugInAggregationMultiFunctionFactory factory = plugInAggregations.getMap().get(config);
            if (factory == null) {
                factory = (PlugInAggregationMultiFunctionFactory) JavaClassHelper.instantiate(PlugInAggregationMultiFunctionFactory.class, config.getMultiFunctionFactoryClassName());
                plugInAggregations.getMap().put(config, factory);
            }
            factory.addAggregationFunction(new PlugInAggregationMultiFunctionDeclarationContext(functionName.toLowerCase(), distinct, engineURI, config));
            return new ExprPlugInAggMultiFunctionNode(distinct, config, factory, functionName);
        }


        // try built-in expanded set of aggregation functions
        return engineImportService.resolveAggExtendedBuiltin(functionName, distinct);
