Example 1 with ROW
use of io.trino.spi.type.StandardTypes.ROW in project trino by trinodb.
the class TestRowParametricType method testTypeSignatureRoundTrip.
@Test
public void testTypeSignatureRoundTrip() {
TypeSignature typeSignature = new TypeSignature(ROW, TypeSignatureParameter.namedTypeParameter(new NamedTypeSignature(Optional.of(new RowFieldName("col1")), BIGINT.getTypeSignature())), TypeSignatureParameter.namedTypeParameter(new NamedTypeSignature(Optional.of(new RowFieldName("col2")), DOUBLE.getTypeSignature())));
List<TypeParameter> parameters = typeSignature.getParameters().stream().map(parameter -> TypeParameter.of(parameter, TESTING_TYPE_MANAGER)).collect(Collectors.toList());
Type rowType = RowParametricType.ROW.createType(TESTING_TYPE_MANAGER, parameters);
assertEquals(rowType.getTypeSignature(), typeSignature);
