Package com.fasterxml.jackson.databind.introspect

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:

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 cannot 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.

Constructor	Description
AnnotatedParameter(AnnotatedWithParams owner, JavaType type, TypeResolutionContext typeContext, AnnotationMap annotations, int index)

Method Summary

Modifier and Type	Method	Description
boolean	equals(Object o)
AnnotatedElement	getAnnotated()	Since there is no matching JDK element, this method will always return null
Class<?>	getDeclaringClass()	Actual physical class in which this member was declared.
int	getIndex()	Accessor for index of this parameter within argument list
Member	getMember()
int	getModifiers()	Returns modifiers of the constructor, as parameters do not have independent modifiers.
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.
Type	getParameterType()
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.
Object	getValue(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(Object pojo, 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.
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 Details

withAnnotations

public AnnotatedParameter withAnnotations(AnnotationMap ann)

Description copied from class: AnnotatedMember

Fluent factory method that will construct a new instance that uses specified instance annotations instead of currently configured ones.

Specified by:

withAnnotations in class AnnotatedMember

getAnnotated

public 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.

getName

public 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 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

Full generic type of the annotated element; definition of what exactly this means depends on sub-class.

Specified by:

getType in class Annotated

getDeclaringClass

public Class<?> getDeclaringClass()

Description copied from class: AnnotatedMember

Actual physical class in which this member was declared.

Specified by:

getDeclaringClass in class AnnotatedMember

getMember

public Member getMember()

Specified by:

getMember in class AnnotatedMember

setValue

public void setValue(Object pojo,
 Object value)
              throws UnsupportedOperationException

Description copied from class: AnnotatedMember

Optional method that can be used to assign value of this member on given object, if this is a supported operation for member type.

This is implemented for fields and single-argument member methods; but not for constructor parameters or other types of methods (like static methods)

Specified by:

setValue in class AnnotatedMember

Throws:

UnsupportedOperationException

getValue

public Object getValue(Object pojo)
                throws UnsupportedOperationException

Description copied from class: AnnotatedMember

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.

This is implemented for fields and no-argument member methods; but not for constructor parameters or other types of methods (like static methods)

Specified by:

getValue in class AnnotatedMember

Throws:

UnsupportedOperationException

getParameterType

public Type getParameterType()

getOwner

public AnnotatedWithParams getOwner()

Accessor for 'owner' of this parameter; method or constructor that has this parameter as member of its argument list.

Returns:

Owner (member or creator) object of this parameter

getIndex

public int getIndex()

Accessor for index of this parameter within argument list

Returns:

Index of this parameter within argument list

hashCode

public int hashCode()

Specified by:

hashCode in class Annotated

equals

public boolean equals(Object o)

Specified by:

equals in class Annotated

toString

public String toString()
