Examples with CustomType org.apache.flink.api.java.operator.JoinOperatorTest.CustomType used on opensource projects

Example 1 with CustomType

use of org.apache.flink.api.java.operator.JoinOperatorTest.CustomType in project flink by apache.

the class CoGroupOperatorTest method testCoGroupKeyExpressions4.

@Test(expected = IllegalArgumentException.class)
public void testCoGroupKeyExpressions4() {
    final ExecutionEnvironment env = ExecutionEnvironment.getExecutionEnvironment();
    DataSet<CustomType> ds1 = env.fromCollection(customTypeData);
    DataSet<CustomType> ds2 = env.fromCollection(customTypeData);
    // should not work, cogroup key non-existent
    ds1.coGroup(ds2).where("myNonExistent").equalTo("myInt");
}

Example 2 with CustomType

    DataSet<Tuple5<Integer, Long, String, Long, Integer>> ds1 = env.fromCollection(emptyTupleData, tupleTypeInfo);
    DataSet<CustomType> ds2 = env.fromCollection(customTypeData);
    // should not work, incompatible types
    ds1.coGroup(ds2).where(2).equalTo(new KeySelector<CustomType, Long>() {

        @Override
        public Long getKey(CustomType value) {
            return value.myLong;
