Class Module

java.lang.Object

edu.internet2.middleware.grouperClientExt.com.fasterxml.jackson.databind.Module

All Implemented Interfaces:

Versioned

Direct Known Subclasses:

SimpleModule

public abstract class Module
extends Object
implements Versioned

Simple interface for extensions that can be registered with ObjectMapper to provide a well-defined set of extensions to default functionality; such as support for new data types.

Method Summary

Modifier and Type	Method	Description
Iterable<? extends Module>	getDependencies()	Returns the list of dependent modules this module has, if any.
abstract String	getModuleName()	Method that returns a display that can be used by Jackson for informational purposes, as well as in associating extensions with module that provides them.
Object	getTypeId()	Method that returns an id that may be used to determine if two Module instances are considered to be of same type, for purpose of preventing multiple registrations of "same type of" module (see MapperFeature.IGNORE_DUPLICATE_MODULE_REGISTRATIONS) If `null` is returned, every instance is considered unique.
abstract void	setupModule(Module.SetupContext context)	Method called by ObjectMapper when module is registered.
abstract Version	version()	Method that returns version of this module.

Method Details

getModuleName

public abstract String getModuleName()

Method that returns a display that can be used by Jackson for informational purposes, as well as in associating extensions with module that provides them.

version

public abstract Version version()

Method that returns version of this module. Can be used by Jackson for informational purposes.

Specified by:

version in interface Versioned

Returns:

Version of the component

getTypeId

public Object getTypeId()

Method that returns an id that may be used to determine if two Module instances are considered to be of same type, for purpose of preventing multiple registrations of "same type of" module (see MapperFeature.IGNORE_DUPLICATE_MODULE_REGISTRATIONS) If `null` is returned, every instance is considered unique. If non-null value is returned, equality of id Objects is used to check whether modules should be considered to be "of same type"

Default implementation returns value of class name (Class.getName()).

Since:

2.5

setupModule

public abstract void setupModule(Module.SetupContext context)

Method called by ObjectMapper when module is registered. It is called to let module register functionality it provides, using callback methods passed-in context object exposes.

getDependencies

public Iterable<? extends Module> getDependencies()

Returns the list of dependent modules this module has, if any. It is called to let modules register other modules as dependencies. Modules returned will be registered before this module is registered, in iteration order.

Since:

2.10
