Usage:
`fieldNames` is field name array
`fieldsType` is field type array
We can acquire field typeinformation by the way:
{code:java}
TypeInformation typeInformation =
TypeStringUtils.readTypeInfo("OBJECT_ARRAY<STRING>");
{code}
{code:java}
ConnectTableDescriptor d =
descriptor.withFormat(
new Csv().fieldDelimiter(fielddelimiter).schema(new
RowTypeInfo(fieldsType,fieldNames))
)
.withSchema(
schema
);
{code}
(1) RowTypeInfo(fieldsType,fieldNames) calls toString method:
Row(name: String, age: Integer, sex: String, datatime:
BasicArrayTypeInfo<String>)
`datatime` field type is BasicArrayTypeInfo<String>.
(2)Schema shema :
schema = schema.field(fieldNames[i],fieldsType[i]);
`datatime` field type is BasicArrayTypeInfo<String>

Code analysis:
`schemaBuilder.field(name, type)` is called when create TableSchema
{code:java}
public Builder field(String name, TypeInformation<?> typeInfo) {
return field(name, fromLegacyInfoToDataType(typeInfo));
}
public static DataType fromLegacyInfoToDataType(TypeInformation<?> typeInfo) {
return LegacyTypeInfoDataTypeConverter.toDataType(typeInfo);
}
public static DataType toDataType(TypeInformation<?> typeInfo) {
// time indicators first as their hashCode/equals is shared with those of
regular timestamps
if (typeInfo instanceof TimeIndicatorTypeInfo) {
return convertToTimeAttributeType((TimeIndicatorTypeInfo) typeInfo);
}
final DataType foundDataType = typeInfoDataTypeMap.get(typeInfo);
if (foundDataType != null) {
return foundDataType;
}
if (typeInfo instanceof RowTypeInfo) {
return convertToRowType((RowTypeInfo) typeInfo);
}
else if (typeInfo instanceof ObjectArrayTypeInfo) {
return convertToArrayType(
typeInfo.getTypeClass(),
((ObjectArrayTypeInfo) typeInfo).getComponentInfo());
}
else if (typeInfo instanceof BasicArrayTypeInfo) {
return createLegacyType(LogicalTypeRoot.ARRAY, typeInfo);
}
else if (typeInfo instanceof MultisetTypeInfo) {
return convertToMultisetType(((MultisetTypeInfo)
typeInfo).getElementTypeInfo());
}
else if (typeInfo instanceof MapTypeInfo) {
return convertToMapType((MapTypeInfo) typeInfo);
}
else if (typeInfo instanceof CompositeType) {
return createLegacyType(LogicalTypeRoot.STRUCTURED_TYPE, typeInfo);
}
return createLegacyType(LogicalTypeRoot.ANY, typeInfo);
}
{code}
if typeinformation is BasicArrayTypeinfo , the code is called:
{code:java}
return createLegacyType(LogicalTypeRoot.ARRAY, typeInfo); }
private static DataType createLegacyType(LogicalTypeRoot typeRoot,
TypeInformation<?> typeInfo) {
return new AtomicDataType(new LegacyTypeInformationType<>(typeRoot,
typeInfo))
.bridgedTo(typeInfo.getTypeClass());
}
{code}
`datatime` field type is LEGACY(BasicArrayTypeInfo<String>)
