CollectionType
public class CollectionLikeType extends TypeBase
Type that represents things that act similar toCollection
; but may or may not be instances of that interface. This specifically allows framework to check for configuration and annotation settings used for Map types, and pass these to custom handlers that may be more familiar with actual type.- See Also:

withContentType
public JavaType withContentType(JavaType contentType)
Description copied from class:JavaType
Mutant factory method that may be called on structured types that have a so-called content type (element of arrays, value type of Maps, referenced type of referential types), and will construct a new instance that is identical to this instance, except that it has specified content type, instead of current one. If content type is already set to given type,this
is returned. If type does not have a content type (which is the case withSimpleType
),IllegalArgumentException
will be thrown.- Specified by:
withContentType
in classJavaType
- Returns:
- Newly created type instance
-
withTypeHandler
public CollectionLikeType withTypeHandler(java.lang.Object h)
Description copied from class:JavaType
"Copy method" that will construct a new instance that is identical to this instance, except that it will have specified type handler assigned.- Specified by:
withTypeHandler
in classJavaType
- Returns:
- Newly created type instance
-
withContentTypeHandler
public CollectionLikeType withContentTypeHandler(java.lang.Object h)
Description copied from class:JavaType
Mutant factory method that will construct a new instance that is identical to this instance, except that it will have specified content type (element type for arrays, value type for Maps and so forth) handler assigned.- Specified by:
withContentTypeHandler
in classJavaType
- Returns:
- Newly created type instance, with given
-
withValueHandler
public CollectionLikeType withValueHandler(java.lang.Object h)
Description copied from class:JavaType
Mutant factory method that will construct a new instance that is identical to this instance, except that it will have specified value handler assigned.- Specified by:
withValueHandler
in classJavaType
- Returns:
- Newly created type instance
-
withContentValueHandler
public CollectionLikeType withContentValueHandler(java.lang.Object h)
Description copied from class:JavaType
Mutant factory method that will construct a new instance that is identical to this instance, except that it will have specified content value handler assigned.- Specified by:
withContentValueHandler
in classJavaType
- Returns:
- Newly created type instance
-
withHandlersFrom
public JavaType withHandlersFrom(JavaType src)
Description copied from class:JavaType
Mutant factory method that will try to copy handlers that the specified source type instance had, if any; this must be done recursively where necessary (as content types may be structured).- Overrides:
withHandlersFrom
in classJavaType
-
withStaticTyping
public CollectionLikeType withStaticTyping()
Description copied from class:JavaType
Method that can be called to get a type instance that indicates that values of the type should be handled using "static typing" for purposes of serialization (as opposed to "dynamic" aka runtime typing): meaning that no runtime information is needed for determining serializers to use. The main use case is to allow forcing of specific root value serialization type, and specifically in resolving serializers for contained types (element types for arrays, Collections and Maps).- Specified by:
withStaticTyping
in classJavaType
-
refine
public JavaType refine(java.lang.Class<?> rawType, TypeBindings bindings, JavaType superClass, JavaType[] superInterfaces)
Description copied from class:JavaType
Mutant factory method that will try to create and return a sub-type instance for known parameterized types; for other types will return `null` to indicate that no just refinement makes necessary sense, without trying to detect special status through implemented interfaces.

- Specified by:
isContainerType
in classJavaType
- Returns:
- True if type represented is a container type; this includes array, Map and Collection types.
-
isCollectionLikeType
public boolean isCollectionLikeType()
- Overrides:
isCollectionLikeType
in classJavaType
- Returns:
- True if type is either true
Collection
type, or something similar (meaning it has at least one type parameter, which describes type of contents)
-

public boolean hasHandlers()
Description copied from class:JavaType
Helper method that checks whether this type, or its (optional) key or content type hasJavaType.getValueHandler()

getErasedSignature
in classTypeBase
- Parameters:

- StringBuilder that was passed in; returned to allow call chaining

in classTypeBase
- Parameters:
sb
- StringBuilder to append signature to- Returns:
- StringBuilder that was passed in; returned to allow call chaining

isTrueCollectionType
@Deprecated public boolean isTrueCollectionType()
Deprecated.Since 2.12 just use instanceofMethod that can be used for checking whether this type is a "real" Collection type; meaning whether it represents a parameterized subtype ofCollection
or just something that acts like one.
