Method Details

from

@Deprecated
public static <S> ClassTypeInformation<S> from(Class<S> type)

Deprecated.

since 3.0. Use TypeInformation.of(org.springframework.core.ResolvableType) instead.

Type Parameters:

S -

Parameters:

type -

Returns:

fromReturnTypeOf

@Deprecated
public static <S> TypeInformation<S> fromReturnTypeOf(Method method)

Deprecated.

since 3.0. Use TypeInformation.fromReturnTypeOf(Method) instead.

Warning: Does not fully resolve generic arguments.

Parameters:

method -

Returns:

getType

public Class<S> getType()

Deprecated, for removal: This API element is subject to removal in a future version.

Description copied from interface: TypeInformation

Returns the type of the property. Will resolve generics and the generic context of

Specified by:

getType in interface TypeInformation<S>

Returns:

getRawTypeInformation

public ClassTypeInformation<?> getRawTypeInformation()

Deprecated, for removal: This API element is subject to removal in a future version.

Description copied from interface: TypeInformation

Returns a TypeInformation to represent the TypeInformation of the raw type of the current instance.

Specified by:

getRawTypeInformation in interface TypeInformation<S>

Returns:

isAssignableFrom

public boolean isAssignableFrom(TypeInformation<?> target)

Deprecated, for removal: This API element is subject to removal in a future version.

Description copied from interface: TypeInformation

Returns if the current TypeInformation can be safely assigned to the given one. Mimics semantics of Class.isAssignableFrom(Class) but takes generics into account. Thus it will allow to detect that a List<Long> is assignable to List<? extends Number>.

Specified by:

isAssignableFrom in interface TypeInformation<S>

Returns:

specialize

public TypeInformation<? extends S> specialize(TypeInformation<?> type)

Deprecated, for removal: This API element is subject to removal in a future version.

Description copied from interface: TypeInformation

Specializes the given (raw) TypeInformation using the context of the current potentially parameterized type, basically turning the given raw type into a parameterized one. Will return the given type as is if no generics are involved.

Specified by:

specialize in interface TypeInformation<S>

Parameters:

type - must not be null.

Returns:

will never be null.

toString

public String toString()

Deprecated, for removal: This API element is subject to removal in a future version.

getParameterTypes

public List<TypeInformation<?>> getParameterTypes(Constructor<?> constructor)

Description copied from interface: TypeInformation

Returns the TypeInformations for the parameters of the given Constructor.

Specified by:

getParameterTypes in interface TypeInformation<S>

Parameters:

constructor - must not be null.

Returns:

getProperty

@Nullable
public TypeInformation<?> getProperty(String name)

Description copied from interface: TypeInformation

Returns the property information for the property with the given name. Supports property traversal through dot notation.

Specified by:

getProperty in interface TypeInformation<S>

Returns:

isCollectionLike

public boolean isCollectionLike()

Description copied from interface: TypeInformation

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. If this returns true you can expect TypeInformation.getComponentType() to return a non-null value.

Specified by:

isCollectionLike in interface TypeInformation<S>

Returns:

getComponentType

@Nullable
public TypeInformation<?> getComponentType()

Description copied from interface: TypeInformation

Returns the component type for Collections or the key type for Maps.

Specified by:

getComponentType in interface TypeInformation<S>

Returns:

doGetComponentType

@Nullable
protected TypeInformation<?> doGetComponentType()

isMap

public boolean isMap()

Description copied from interface: TypeInformation

Returns whether the property is a Map. If this returns true you can expect TypeInformation.getComponentType() as well as TypeInformation.getMapValueType() to return something not null.

Specified by:

isMap in interface TypeInformation<S>

Returns:

getMapValueType

@Nullable
public TypeInformation<?> getMapValueType()

Description copied from interface: TypeInformation

Will return the type of the value in case the underlying type is a Map.

Specified by:

Specified by:

getActualType in interface TypeInformation<S>

Returns:

the map value, collection component type or the current type, null it the current type is a raw Map or Collection.

getReturnType

public TypeInformation<?> getReturnType(Method method)

Description copied from interface: TypeInformation

Returns a TypeInformation for the return type of the given Method. Will potentially resolve generics information against the current types type parameter bindings.

Specified by:

getReturnType in interface TypeInformation<S>

Parameters:
