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

Example 1 with ParamType

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

the class GenericsUtilTest method shouldResolveArraySchemaWithMapping.

@Test
public void shouldResolveArraySchemaWithMapping() {
    // Given:
    final GenericType a = GenericType.of("A");
    final ParamType array = ArrayType.of(a);
    final ImmutableMap<GenericType, SqlType> mapping = ImmutableMap.of(a, SqlTypes.STRING);
    // When:
    final SqlType resolved = GenericsUtil.applyResolved(array, mapping);
    // Then:
    assertThat(resolved, is(SqlTypes.array(SqlTypes.STRING)));
}

Example 2 with ParamType

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

the class GenericsUtilTest method shouldFindAllConstituentGenerics.

@Test

    // Given:
    final GenericType a = GenericType.of("A");
    final GenericType b = GenericType.of("B");
    final GenericType c = GenericType.of("C");
    final GenericType d = GenericType.of("D");
    final ParamType map = MapType.of(GenericType.of("C"), GenericType.of("D"));
    final StructType complexSchema = StructType.builder().field("a", a).field("b", b).field("c", map).build();
    // When:
    final Set<ParamType> generics = GenericsUtil.constituentGenerics(complexSchema);
    // Then:
    assertThat(generics, containsInAnyOrder(a, b, c, d));
}
