Deprecated.
This class will be removed in future versions as it uses the old type system. It is recommended to use DataTypes instead which uses the new type system based on instances of DataType. Please make sure to use either the old or the new type system consistently to avoid unintended behavior. See the website documentation for more information.

This class enumerates all supported types of the Table API & SQL.

```
    Deprecated.
    
    Returns type information for Row with fields of the given types.
    A row is a variable-length, null-aware composite type for storing multiple values in a deterministic field order. Every field can be null regardless of the field's type. The type of row fields cannot be automatically inferred; therefore, it is required to provide type information whenever a row is used.
    The schema of rows can have up to Integer.MAX_VALUE fields, however, all row instances must strictly adhere to the schema defined by the type info.
    This method generates type information with fields of the given types; the fields have the default names (f0, f1, f2 ..).
    
    Parameters:
    
    types - The types of the row fields, e.g., Types.STRING(), Types.INT()
  - ROW
```
public static org.apache.flink.api.common.typeinfo.TypeInformation<org.apache.flink.types.Row> ROW(String[] fieldNames,
                                                                                                   org.apache.flink.api.common.typeinfo.TypeInformation<?>[] types)
```
    Deprecated.
    
    Returns type information for Row with fields of the given types and with given names.
    A row is a variable-length, null-aware composite type for storing multiple values in a deterministic field order. Every field can be null independent of the field's type. The type of row fields cannot be automatically inferred; therefore, it is required to provide type information whenever a row is used.
    The schema of rows can have up to Integer.MAX_VALUE fields, however, all row instances must strictly adhere to the schema defined by the type info.
    
    Parameters:
    
    fieldNames - The array of field names
    
    types - The types of the row fields, e.g., Types.STRING(), Types.INT()

```
    Deprecated.
    
    Generates type information for an array consisting of Java primitive elements. The elements do not support null values.
    
    Parameters:
    
    elementType - type of the array elements; e.g. Types.INT()
  - OBJECT_ARRAY
```

```
    Deprecated.
    
    Generates type information for an array consisting of Java object elements. Null values for elements are supported.
    
    Parameters:
    
    elementType - type of the array elements; e.g. Types.INT()
  - MAP
```
public static <K,V> org.apache.flink.api.common.typeinfo.TypeInformation<Map<K,V>> MAP(org.apache.flink.api.common.typeinfo.TypeInformation<K> keyType,
                                                                                                   org.apache.flink.api.common.typeinfo.TypeInformation<V> valueType)
```
    Deprecated.
    
    Generates type information for a Java HashMap. Null values in keys are not supported. An entry's value can be null.
    
    Parameters:
    
    keyType - type of the keys of the map e.g. Types.STRING()
    
    valueType - type of the values of the map e.g. Types.STRING()
  - MULTISET
```
public static <E> org.apache.flink.api.common.typeinfo.TypeInformation<Map<E,Integer>> MULTISET(org.apache.flink.api.common.typeinfo.TypeInformation<E> elementType)
```
    Deprecated.
    
    Generates type information for a Multiset. A Multiset is baked by a Java HashMap and maps an arbitrary key to an integer value. Null values in keys are not supported.
    
    Parameters:
    
    elementType - type of the elements of the multiset e.g. Types.STRING()
