java.lang.Object
com.fasterxml.jackson.core.type.ResolvedType
All Implemented Interfaces:
JsonSerializable, Serializable, Type

public class IterationType extends SimpleType
Specialized SimpleType for types that are allow iteration over Collection(-like) types: this includes types like Iterator. Iterated (content) type is accessible using getContentType().

2.16

    • 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 via TypeModifier
      Parameters:
      baseType - Resolved non-iteration type (usually SimpleType) that is being upgraded
      iteratedType - Iterated type; usually the first and only type parameter, but not necessarily
    • construct

      public static IterationType construct(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 with SimpleType), IllegalArgumentException will be thrown.
      Overrides:
      withContentType in class SimpleType
      Returns:
      Newly created type instance
    • withTypeHandler

      public IterationType withTypeHandler(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 class SimpleType
      Parameters:
      h - Handler to pass to new instance created
      Returns:
      Newly created type instance with same type information, specified handler
    • withContentTypeHandler

      public IterationType withContentTypeHandler(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 class SimpleType
      Parameters:
      h - Handler to pass to new instance created
      Returns:
      Newly created type instance with same type information, specified handler
    • withValueHandler

      public IterationType withValueHandler(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 class SimpleType
      Parameters:
      h - Handler to pass to new instance created
      Returns:
      Newly created type instance with same type information, specified handler
    • withContentValueHandler

      public IterationType withContentValueHandler(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 class SimpleType
      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 class SimpleType
    • refine

      public JavaType refine(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.
      Overrides:
      refine in class SimpleType
    • buildCanonicalName

      protected String buildCanonicalName()
      Overrides:
      buildCanonicalName in class SimpleType
    • getContentType

      public JavaType getContentType()
      Overrides:
      getContentType in class JavaType
    • hasContentType

      public boolean hasContentType()
      Description copied from class: JavaType
      Accessor that allows determining whether JavaType.getContentType() should return a non-null value (that is, there is a "content type") or not. True if JavaType.isContainerType() or ResolvedType.isReferenceType() return true.
      Overrides:
      hasContentType in class SimpleType
    • isIterationType

      public boolean isIterationType()
      Description copied from class: JavaType
      Method that returns true if this instance is of type IterationType.
      Overrides:
      isIterationType in class JavaType
      Returns:
      True if this type is considered "iteration type"
    • getErasedSignature

      public StringBuilder getErasedSignature(StringBuilder sb)
      Description copied from class: JavaType
      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 class SimpleType
      Parameters:
      sb - StringBuilder to append signature to
      Returns:
      StringBuilder that was passed in; returned to allow call chaining

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