      Fields 
      Modifier and Type Field Description
      private java.lang.reflect.Constructor<?> constructorForFieldTypeWithSizeHint
      The constructor with int-valued size hint for the type of the field, or null if this is not a Collection or Map.
      private java.lang.reflect.Constructor<?> defaultConstructorForFieldType
      The default (no-arg) constructor for the type of the field, or null if this is a primitive field, or if intConstructorForFieldType is non-null.
      (package private) java.lang.reflect.Field field
      The field.
      private java.lang.reflect.Type fieldTypePartiallyResolved
      The type of the field after any concrete type arguments of a specific subclass have been substituted into type parameter variables.
      private boolean hasUnresolvedTypeVariables
      True if the field still has unresolved type variables from the defining subclass.
      private boolean isTypeVariable
      If the type of this field is a type variable, it could be any type, so we need to defer getting and caching the constructor in this case.
      private FieldTypeInfo.PrimitiveType primitiveType
      The index of the type: 0 for non-primitive type; 1-8 for primitive types.

      Constructor Description
      FieldTypeInfo​(java.lang.reflect.Field field, java.lang.reflect.Type fieldTypePartiallyResolved, ClassFieldCache classFieldCache)
      Constructor.

    • Field Detail

      • field

        final java.lang.reflect.Field field
        The field.

      • fieldTypePartiallyResolved

        private final java.lang.reflect.Type fieldTypePartiallyResolved
        The type of the field after any concrete type arguments of a specific subclass have been substituted into type parameter variables. There may still be type variables present, if the subclass itself has unresolved type variables.

      • hasUnresolvedTypeVariables

        private final boolean hasUnresolvedTypeVariables
        True if the field still has unresolved type variables from the defining subclass.

      • isTypeVariable

        private final boolean isTypeVariable
        If the type of this field is a type variable, it could be any type, so we need to defer getting and caching the constructor in this case.

      • primitiveType

        private final FieldTypeInfo.PrimitiveType primitiveType
        The index of the type: 0 for non-primitive type; 1-8 for primitive types.

      • constructorForFieldTypeWithSizeHint

        private java.lang.reflect.Constructor<?> constructorForFieldTypeWithSizeHint
        The constructor with int-valued size hint for the type of the field, or null if this is not a Collection or Map.

      • defaultConstructorForFieldType

        private java.lang.reflect.Constructor<?> defaultConstructorForFieldType
        The default (no-arg) constructor for the type of the field, or null if this is a primitive field, or if intConstructorForFieldType is non-null.
