## Protected Attributes
std::set< std::string > | m_supportedOptions
| Set of optional settings supported by handler.

## Friends
void | registerSessionInitiators ()
| Registers SessionInitiator implementations.

## Detailed Description

Pluggable runtime functionality that handles initiating sessions.

By default, SessionInitiators look for an entityID on the incoming request and pass control to the specialized run method.

## Member Function Documentation

## ◆ checkCompatibility()

bool shibsp::SessionInitiator::checkCompatibility | ( | SPRequest & | request,
|  | bool | isHandler
| ) |  | const
| protected

Examines the request and applicable settings to determine whether the handler is able to support the request.

If the handler is within a chain, the method will return false, otherwise an exception will be raised.

Parameters

  request | SP request context
  isHandler | true iff executing in the context of a direct handler invocation

Returns
  true iff the request appears to be compatible

## ◆ doGenerateMetadata()

void shibsp::SessionInitiator::doGenerateMetadata | ( | opensaml::saml2md::SPSSODescriptor & | role,
|  | const char * | handlerURL
| ) |  | const

Generates RequestInitiator metadata when instructed.

Allows subclasses to decide whether it's appropriate to do so instead of requiring them to override the method to stop it.

Parameters

  role | role object to inject metadata into
  handlerURL | base of endpoint to generate metadata with

## ◆ generateMetadata()

void shibsp::SessionInitiator::generateMetadata | ( | opensaml::saml2md::SPSSODescriptor & | role,
|  | const char * | handlerURL
| ) |  | const
| virtual

Generates and/or modifies metadata reflecting the Handler.

The default implementation does nothing.

Parameters

  role | metadata role to decorate
  handlerURL | base location of handler's endpoint

Reimplemented from shibsp::Handler.

## ◆ getEventType()

const char * shibsp::SessionInitiator::getEventType | ( |  | ) | const
| virtual

Get the type of event, as input to error handling in response to errors raised by this handler.

Returns
  an event type for error handling

Reimplemented from shibsp::Handler.

## ◆ getSupportedOptions()

virtual const std::set< std::string > & shibsp::SessionInitiator::getSupportedOptions | ( |  | ) | const
| virtual

Indicates the set of optional settings supported by the handler.

Returns
  a set of the optional settings supported

## ◆ getType()

const char * shibsp::SessionInitiator::getType | ( |  | ) | const
| virtual

Returns the "type" of the Handler plugin.

Returns
  a Handler type

Reimplemented from shibsp::Handler.

## ◆ newAuthnRequestEvent()

virtual AuthnRequestEvent * shibsp::SessionInitiator::newAuthnRequestEvent | ( | const Application & | application,
|  | const xmltooling::HTTPRequest * | request = `nullptr`
| ) |  | const
| protected virtual

Creates a new AuthnRequestEvent for the event log.

Parameters

  application | the Application associated with the event
  request | the HTTP client request associated with the event, or nullptr

Returns
  a fresh AuthnRequestEvent, prepopulated by the input parameters, or nullptr if an error occurs

## ◆ remap()

const char * shibsp::SessionInitiator::remap | ( | const char * | src,
|  | xmltooling::logging::Category & | log
| ) |  | const
| virtual

Remap a name (or return it unchanged).

Parameters

  src | original name
  log | logger to use

Returns
  the name to use

Implements shibsp::DOMPropertySet::Remapper.

## ◆ run() [1/2]

std::pair< bool, long > shibsp::SessionInitiator::run | ( | SPRequest & | request,
|  | bool | isHandler = `true`
| ) |  | const
| virtual

Executes handler functionality as an incoming request.

Handlers can be run either directly by incoming web requests or indirectly/implicitly during other SP processing.

Parameters

  request | SP request context
  isHandler | true iff executing in the context of a direct handler invocation

Returns
  a pair containing a "request completed" indicator and a server-specific response code

Implements shibsp::Handler.

## ◆ run() [2/2]

virtual std::pair< bool, long > shibsp::SessionInitiator::run | ( | SPRequest & | request,
|  | std::string & | entityID,
|  | bool | isHandler = `true`
| ) |  | const
| pure virtual

Executes an incoming request.

SessionInitiators can be run either directly by incoming web requests or indirectly/implicitly during other SP processing.

Parameters

  request | SP request context
  entityID | the name of an IdP to request a session from, if known
  isHandler | true iff executing in the context of a direct handler invocation

Returns
  a pair containing a "request completed" indicator and a server-specific response code
