Example 1 with TableAggregateFunction

use of org.apache.flink.table.functions.TableAggregateFunction in project flink by apache.

the class FunctionCatalog method registerTempSystemAggregateFunction.

/**
 * @deprecated Use {@link #registerTemporarySystemFunction(String, FunctionDefinition, boolean)}
 *     instead.
 */
@Deprecated
public <T, ACC> void registerTempSystemAggregateFunction(String name, ImperativeAggregateFunction<T, ACC> function, TypeInformation<T> resultType, TypeInformation<ACC> accType) {
    UserDefinedFunctionHelper.prepareInstance(config, function);
    final FunctionDefinition definition;
    if (function instanceof AggregateFunction) {
