Examples with IdentityConversion org.apache.flink.table.functions.hive.conversion.IdentityConversion used on opensource projects

Example 1 with IdentityConversion

use of org.apache.flink.table.functions.hive.conversion.IdentityConversion in project flink by apache.

the class HiveGenericUDTF method open.

@Override
public void open(FunctionContext context) throws Exception {
    function = hiveFunctionWrapper.createFunction();
    function.setCollector(input -> {
        Row row = (Row) HiveInspectors.toFlinkObject(returnInspector, input, hiveShim);
        HiveGenericUDTF.this.collect(row);
    });
    ObjectInspector[] argumentInspectors = HiveInspectors.toInspectors(hiveShim, constantArguments, argTypes);
    returnInspector = function.initialize(argumentInspectors);
    isArgsSingleArray = HiveFunctionUtil.isSingleBoxedArray(argTypes);
    conversions = new HiveObjectConversion[argumentInspectors.length];
    for (int i = 0; i < argumentInspectors.length; i++) {
        conversions[i] = HiveInspectors.getConversion(argumentInspectors[i], argTypes[i].getLogicalType(), hiveShim);
    }
    allIdentityConverter = Arrays.stream(conversions).allMatch(conv -> conv instanceof IdentityConversion);
}

Example 2 with IdentityConversion

use of org.apache.flink.table.functions.hive.conversion.IdentityConversion in project flink by apache.

the class HiveSimpleUDF method openInternal.

@Override

    function = hiveFunctionWrapper.createFunction();
    List<TypeInfo> typeInfos = new ArrayList<>();
