Method Detail

upgradeFrom
public static IterationType upgradeFrom(JavaType baseType, JavaType iteratedType)
Factory method that can be used to "upgrade" a basic type into iteration type; usually done viaTypeModifier
- Parameters:
baseType
- Resolved non-iteration type (usuallySimpleType
) that is being upgradediteratedType
- Iterated type; usually the first and only type parameter, but not necessarily
-
construct
public static IterationType construct(java.lang.Class<?> cls, TypeBindings bindings, JavaType superClass, JavaType[] superInts, JavaType iteratedType)
-
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.- Overrides:
withContentType
in classSimpleType
- Returns:
- Newly created type instance
-
withTypeHandler
public IterationType withTypeHandler(java.lang.Object h)
Description copied from class:JavaType
Internal method that should not be used by any code outside of jackson-databind: only used internally by databind. May be removed from Jackson 3.0.This mutant factory method will construct a new instance that is identical to this instance, except that it will have specified type handler assigned.
- Overrides:
withTypeHandler
in classSimpleType
- Parameters:
h
- Handler to pass to new instance created- Returns:
- Newly created type instance with same type information, specified handler
-
withContentTypeHandler
public IterationType withContentTypeHandler(java.lang.Object h)
Description copied from class:JavaType
Internal method that should not be used by any code outside of jackson-databind: only used internally by databind. May be removed from Jackson 3.0.This mutant factory method 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.
- Overrides:
withContentTypeHandler
in classSimpleType
- Parameters:
h
- Handler to pass to new instance created- Returns:
- Newly created type instance with same type information, specified handler
-
withValueHandler
public IterationType withValueHandler(java.lang.Object h)
Description copied from class:JavaType
Internal method that should not be used by any code outside of jackson-databind: only used internally by databind. May be removed from Jackson 3.0.This mutant factory method will construct a new instance that is identical to this instance, except that it will have specified value handler assigned.
- Overrides:
withValueHandler
in classSimpleType
- Parameters:
h
- Handler to pass to new instance created- Returns:
- Newly created type instance with same type information, specified handler
-
withContentValueHandler
public IterationType withContentValueHandler(java.lang.Object h)
Description copied from class:JavaType
Internal method that should not be used by any code outside of jackson-databind: only used internally by databind. May be removed from Jackson 3.0.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.
- Overrides:
withContentValueHandler
in classSimpleType
- Parameters:
h
- Handler to pass to new instance created- Returns:
- Newly created type instance with same type information, specified handler
-
withStaticTyping
public IterationType 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).- Overrides:
withStaticTyping
in classSimpleType
-
refine
public JavaType refine(java.lang.Class<?> rawType, TypeBindings bindings, JavaType superClass, JavaType[] superInterfaces)

public JavaType getContentType()
- Overrides:
getContentType
in classJavaType
-
hasContentType
public boolean hasContentType()
Description copied from class:JavaType
Accessor that allows determining whetherJavaType.getContentType()
should return a non-null value (that is, there is a "content type") or not. True ifJavaType.isContainerType()
orResolvedType.isReferenceType()
return true.- Overrides:
hasContentType
in classSimpleType
-
isIterationType
public boolean isIterationType()

-
getErasedSignature
public java.lang.StringBuilder getErasedSignature(java.lang.StringBuilder sb)

Method for accessing signature without generic type information, in form compatible with all versions of JVM, and specifically used for type descriptions when generating byte code.- Overrides:
getErasedSignature
in classSimpleType
- Parameters:
sb
- StringBuilder to append signature to- Returns:
- StringBuilder that was passed in; returned to allow call chaining
