static <S> TypeInformation<S> |
fromReturnTypeOf(Method method)
Creates a
TypeInformation from the given method's return type. |
TypeInformation<?> |
getActualType()
Transparently returns the
Map value type if the type is a Map , returns the
component type if the type TypeInformation.isCollectionLike() or the simple type if none of this applies. |
TypeInformation<?> |
getComponentType()
Returns the component type for
Collection s or the key type for Map s. |
TypeInformation<?> |
getMapValueType()
Will return the type of the value in case the underlying type is a
Map . |
List<TypeInformation<?>> |
getParameterTypes(Constructor<?> constructor)
Returns the
TypeInformation s for the parameters of the given Constructor . |
List<TypeInformation<?>> |
getParameterTypes(Method method)
Returns the
TypeInformation s for the parameters of the given Method . |
TypeInformation<?> |
getProperty(String fieldname)
Returns the property information for the property with the given name.
|
ClassTypeInformation<?> |
getRawTypeInformation()
Returns a
ClassTypeInformation to represent the TypeInformation of the raw type of the current
instance. |
TypeInformation<?> |
getReturnType(Method method)
Returns a
TypeInformation for the return type of the given Method . |
TypeInformation<?> |
getSuperTypeInformation(Class<?> superType)
Returns the
TypeInformation for the given raw super type. |
Class<S> |
getType()
Returns the type of the property.
|
List<TypeInformation<?>> |
getTypeArguments()
Returns the
TypeInformation for the type arguments of the current TypeInformation . |
protected Map<TypeVariable<?>,Type> |
getTypeVariableMap()
Returns the type variable map.
|
int |
hashCode() |
boolean |
isAssignableFrom(TypeInformation<?> target)
Returns if the current
TypeInformation can be safely assigned to the given one. |
boolean |
isCollectionLike()
Returns whether the type can be considered a collection, which means it's a container of elements, e.g. a
Collection and Array or anything implementing Iterable . |
boolean |
isMap()
Returns whether the property is a
Map . |
protected Class<S> |
resolveType(Type type)
Resolves the given type into a plain
Class . |
TypeInformation<? extends S> |
specialize(ClassTypeInformation<?> type)
Specializes the given (raw)
ClassTypeInformation using the context of the current potentially parameterized
type, basically turning the given raw type into a parameterized one. |
