Examples with GenericType io.confluent.ksql.function.types.GenericType used on opensource projects

Example 6 with GenericType

use of io.confluent.ksql.function.types.GenericType in project ksql by confluentinc.

the class GenericsUtilTest method shouldNotMapGenericsForNonSqlLambdaResolved.

@Test
public void shouldNotMapGenericsForNonSqlLambdaResolved() {
    // Given:
    final GenericType typeA = GenericType.of("A");
    final GenericType typeB = GenericType.of("B");
    final GenericType typeC = GenericType.of("C");
    final LambdaType a = LambdaType.of(ImmutableList.of(typeA, typeC), typeB);
    final SqlArgument instance = SqlArgument.of(SqlLambda.of(2));
    // When:
    final Map<GenericType, SqlType> mapping = GenericsUtil.reserveGenerics(a, instance);
    // Then:
    // the map should be empty since the instance type was a SqlLambda without any types resolved
    assertThat(mapping.size(), is(0));
}

Example 7 with GenericType

use of io.confluent.ksql.function.types.GenericType in project ksql by confluentinc.

    // When:
    final Map<GenericType, SqlType> mapping = GenericsUtil.reserveGenerics(a, instance);
    // Then:
