## Class AnnotatedParameter

- java.lang.Object
- - com.fasterxml.jackson.databind.introspect.Annotated
  - - com.fasterxml.jackson.databind.introspect.AnnotatedMember
    - - com.fasterxml.jackson.databind.introspect.AnnotatedParameter

- All Implemented Interfaces:
    java.io.Serializable

      public final class AnnotatedParameter
      extends AnnotatedMember

  Object that represents method parameters, mostly so that associated annotations can be processed conveniently. Note that many of accessors can not return meaningful values since parameters do not have stand-alone JDK objects associated; so access should mostly be limited to checking annotation values which are properly aggregated and included.

    Methods
    Modifier and Type | Method and Description
    --- | ---
    `boolean` | `equals(java.lang.Object o)`
    `java.lang.reflect.AnnotatedElement` | `getAnnotated()` Since there is no matching JDK element, this method will always return null
    `java.lang.Class<?>` | `getDeclaringClass()` Actual physical class in which this memmber was declared.
    `java.lang.reflect.Type` | `getGenericType()` Deprecated.
    `int` | `getIndex()` Accessor for index of this parameter within argument list
    `java.lang.reflect.Member` | `getMember()`
    `int` | `getModifiers()` Returns modifiers of the constructor, as parameters do not have independent modifiers.
    `java.lang.String` | `getName()` Parameters have no names in bytecode (unlike in source code), will always return empty String ("").
    `AnnotatedWithParams` | `getOwner()` Accessor for 'owner' of this parameter; method or constructor that has this parameter as member of its argument list.
    `java.lang.reflect.Type` | `getParameterType()`
    `java.lang.Class<?>` | `getRawType()` "Raw" type (type-erased class) of the annotated element; definition of what exactly this means depends on sub-class.
    `JavaType` | `getType()` Full generic type of the annotated element; definition of what exactly this means depends on sub-class.
    `java.lang.Object` | `getValue(java.lang.Object pojo)` Optional method that can be used to access the value of this member on given object, if this is a supported operation for member type.
    `int` | `hashCode()`
    `void` | `setValue(java.lang.Object pojo, java.lang.Object value)` Optional method that can be used to assign value of this member on given object, if this is a supported operation for member type.
    `java.lang.String` | `toString()`
    `AnnotatedParameter` | `withAnnotations(AnnotationMap ann)` Fluent factory method that will construct a new instance that uses specified instance annotations instead of currently configured ones.

  - ### Method Detail

    - #### withAnnotations

          public AnnotatedParameter withAnnotations(AnnotationMap ann)

      Description copied from class: `Annotated`
      Fluent factory method that will construct a new instance that uses specified instance annotations instead of currently configured ones.
      Specified by:
        `withAnnotations` in class `Annotated`

    - #### getAnnotated

          public java.lang.reflect.AnnotatedElement getAnnotated()

      Since there is no matching JDK element, this method will always return null
      Specified by:
        `getAnnotated` in class `Annotated`

    - #### getModifiers

          public int getModifiers()

      Returns modifiers of the constructor, as parameters do not have independent modifiers.
      Specified by:
        `getModifiers` in class `Annotated`

    - #### getName

          public java.lang.String getName()

      Parameters have no names in bytecode (unlike in source code), will always return empty String ("").
      Specified by:
        `getName` in class `Annotated`

    - #### getRawType

          public java.lang.Class<?> getRawType()

      Description copied from class: `Annotated`
      "Raw" type (type-erased class) of the annotated element; definition of what exactly this means depends on sub-class.
      Specified by:
        `getRawType` in class `Annotated`

    - #### getType

          public JavaType getType()

      Description copied from class: `Annotated`

      Specified by:
        `getType` in class `Annotated`

    - #### getGenericType

          @Deprecated
          public java.lang.reflect.Type getGenericType()

      Deprecated.
      Description copied from class: `Annotated`
      JDK declared generic type of the annotated element; definition of what exactly this means depends on sub-class. Note that such type can not be reliably resolved without `TypeResolutionContext`, and as a result use of this method was deprecated in Jackson 2.7: see `Annotated.getType()` for replacement.

        `getGenericType` in class `Annotated`
