Class SimpleType

  • All Implemented Interfaces:
    JsonSerializable, JsonSerializableWithType
    public final class SimpleType
extends TypeBase
    Simple types are defined as anything other than one of recognized container types (arrays, Collections, Maps). For our needs we need not know anything further, since we have no way of dealing with generic types other than Collections and Maps.

    • Field Detail

      • _typeParameters

        protected final JavaType[] _typeParameters
        Generic type arguments for this type.

      • _typeNames

        protected final java.lang.String[] _typeNames
        Names of generic type arguments for this type; will match values in _typeParameters

    • Method Detail

      • constructUnsafe

        public static SimpleType constructUnsafe​(java.lang.Class<?> raw)
        Method used by core Jackson classes: NOT to be used by application code.

        NOTE: public only because it is called by ObjectMapper which is not in same package

      • construct

        public static SimpleType construct​(java.lang.Class<?> cls)

      • withTypeHandler

        public SimpleType 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 class JavaType
        Returns:
        Newly created type instance

      • withContentTypeHandler

        public JavaType withContentTypeHandler​(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 its content type will have specified type handler assigned.
        Specified by:
        withContentTypeHandler in class JavaType
        Returns:
        Newly created type instance

      • isContainerType

        public boolean isContainerType()
        Specified by:
        isContainerType in class JavaType
        Returns:
        True if type represented is a container type; this includes array, Map and Collection types.

      • containedTypeCount

        public int containedTypeCount()
        Description copied from class: JavaType
        Method for checking how many contained types this type has. Contained types are usually generic types, so that generic Maps have 2 contained types.
        Overrides:
        containedTypeCount in class JavaType

      • containedType

        public JavaType containedType​(int index)
        Description copied from class: JavaType
        Method for accessing definitions of contained ("child") types.
        Overrides:
        containedType in class JavaType
        Parameters:
        index - Index of contained type to return
        Returns:
        Contained type at index, or null if no such type exists (no exception thrown)

      • containedTypeName

        public java.lang.String containedTypeName​(int index)
        Description copied from class: JavaType
        Method for accessing name of type variable in indicated position. If no name is bound, will use placeholders (derived from 0-based index); if no type variable or argument exists with given index, null is returned.
        Overrides:
        containedTypeName in class JavaType
        Parameters:
        index - Index of contained type to return
        Returns:
        Contained type at index, or null if no such type exists (no exception thrown)

      • getErasedSignature

        public java.lang.StringBuilder getErasedSignature​(java.lang.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.
        Specified by:
        getErasedSignature in class TypeBase
        Parameters:
        sb - StringBuilder to append signature to
        Returns:
        StringBuilder that was passed in; returned to allow call chaining

      • getGenericSignature

        public java.lang.StringBuilder getGenericSignature​(java.lang.StringBuilder sb)
        Specified by:
        getGenericSignature in class TypeBase
        Parameters:
        sb - StringBuilder to append signature to
        Returns:
        StringBuilder that was passed in; returned to allow call chaining
