  - isBasicType
```
@PublicEvolving
public boolean isBasicType()
```
    Description copied from class: TypeInformation
    
    Checks if this type information represents a basic type. Basic types are defined in BasicTypeInfo and are primitives, their boxing types, Strings, Date, Void, ...
    
    Specified by:
    
    isBasicType in class TypeInformation<T>
    
    Returns:
    
    True, if this type information describes a basic type, false otherwise.
  - isTupleType
```
@PublicEvolving
public boolean isTupleType()
```
    Description copied from class: TypeInformation
    
    Checks if this type information represents a Tuple type. Tuple types are subclasses of the Java API tuples.
    
    Specified by:
    
    isTupleType in class TypeInformation<T>
    
    Returns:
    
    True, if this type information describes a tuple type, false otherwise.
  - getArity
```
@PublicEvolving
public int getArity()
```
    Description copied from class: TypeInformation
    
    Gets the arity of this type - the number of fields without nesting.
    
    Specified by:
    
    getArity in class TypeInformation<T>
    
    Returns:
    
    Gets the number of fields in this type without nesting.
  - getTotalFields
```
@PublicEvolving
public int getTotalFields()
```
    Description copied from class: TypeInformation
    
    Gets the number of logical fields in this type. This includes its nested and transitively nested fields, in the case of composite types. In the example above, the OuterType type has three fields in total.
    The total number of fields must be at least 1.
    
    Specified by:
    
    getTotalFields in class TypeInformation<T>
    
    Returns:
    
    The number of fields in this type, including its sub-fields (for composite types)
  - getTypeClass
```
@PublicEvolving
public Class<T> getTypeClass()
```
    Description copied from class: TypeInformation
    
    Gets the class of the type represented by this type information.
    
    Specified by:
    
    getTypeClass in class TypeInformation<T>
    
    Returns:
    
    The class of the type represented by this type information.
  - getComponentTypeClass

```
  - getComponentInfo
```
@PublicEvolving
public TypeInformation<C> getComponentInfo()
```
  - isKeyType
```
@PublicEvolving
public boolean isKeyType()
```
    Description copied from class: TypeInformation
    
    Checks whether this type can be used as a key. As a bare minimum, types have to be hashable and comparable to be keys.
    
    Specified by:
    
    isKeyType in class TypeInformation<T>
    
    Returns:
    
    True, if the type can be used as a key, false otherwise.
  - createSerializer
```
@PublicEvolving
public TypeSerializer<T> createSerializer(SerializerConfig serializerConfig)
```
    Description copied from class: TypeInformation
    
    Creates a serializer for the type. The serializer may use the ExecutionConfig for parameterization.
    
    Overrides:
    
    createSerializer in class TypeInformation<T>
    
    Parameters:
    
    serializerConfig - The config used to parameterize the serializer.
    
    Returns:
    
    A serializer for this type.
  - createSerializer
```
@Deprecated
@PublicEvolving
public TypeSerializer<T> createSerializer(ExecutionConfig config)
```
    Deprecated.
    
    Description copied from class: TypeInformation
    
    Create TypeSerializer for this type.
    
    Specified by:
    
    createSerializer in class TypeInformation<T>
    
    Parameters:
    
    config - the configuration of this job execution
  - equals
```
public boolean equals(Object obj)
```
    Specified by:
    
    equals in class TypeInformation<T>
  - hashCode
```

    Specified by:
    
    hashCode in class TypeInformation<T>
  - canEqual
```
public boolean canEqual(Object obj)
```
    Description copied from class: TypeInformation
    
    Returns true if the given object can be equaled with this object. If not, it returns false.
    
    Specified by:
    
    canEqual in class TypeInformation<T>
    
    Parameters:
    
    obj - Object which wants to take part in the equality relation
    
    Returns:
    
    true if obj can be equaled with this, otherwise false
  - toString
