Class ConnectorService

java.lang.Object
  org.springframework.extensions.webscripts.connector.ConnectorService

All Implemented Interfaces:

EventListener, org.springframework.context.ApplicationContextAware, org.springframework.context.ApplicationListener

public class ConnectorService
extends Object
implements org.springframework.context.ApplicationListener, org.springframework.context.ApplicationContextAware

The ConnectorService acts as a singleton that can be used to build any of the objects utilized by the Connector layer.

This class is mounted as a Spring Bean within the Web Script Framework so that developers can access it from the application context.

ConnectorService

public ConnectorService()

Method Detail

setConfigService

public void setConfigService(ConfigService configService)

Sets the config service.

Parameters:

configService - the new config service

setApplicationContext

public void setApplicationContext(org.springframework.context.ApplicationContext applicationContext)

Sets the application config

Specified by:

setApplicationContext in interface org.springframework.context.ApplicationContextAware

Parameters:

applicationContxt - the application context

getConfigService

public ConfigService getConfigService()

Gets the config service.

Returns:

the config service

onApplicationEvent

public void onApplicationEvent(org.springframework.context.ApplicationEvent event)

Specified by:

onApplicationEvent in interface org.springframework.context.ApplicationListener

getConnector

public Connector getConnector(String endpointId)
                       throws ConnectorServiceException

Retrieves a Connector to a given endpoint.

This Connector has no given user context and will not pass any authentication credentials. Therefore only endpoints that do not require authentication or have "declared" authentication as part of the endpoint config should be used. This Connector also will not manage connector session state. Thus, it is generally less preferred to use these connectors over those provided by getConnector(endpointId, session)

Parameters:

endpointId - the endpoint id

Returns:

the connector

Throws:

ConnectorServiceException

getConnector

public Connector getConnector(String endpointId,
                              javax.servlet.http.HttpSession session)
                       throws ConnectorServiceException

Retrieves a Connector to a given endpoint.

This Connector has no given user context and will not pass any authentication credentials. Therefore only endpoints that do not require authentication or have "declared" authentication as part of the endpoint config should be used. Cookie and token state will be session bound and reusable on subsequent invocations.

Parameters:

endpointId - the endpoint id

session - the HTTP session

Returns:

the connector

Throws:

ConnectorServiceException

getConnector

public Connector getConnector(String endpointId,
                              String userId,
                              javax.servlet.http.HttpSession session)
                       throws ConnectorServiceException

Retrieves a Connector for the given endpoint that is scoped to the given user.

If the provided endpoint is configured to use an Authenticator, then the Connector instance returned will be wrapped as an AuthenticatingConnector.

Cookie and token state will be session bound and reusable on subsequent invocations.

Parameters:

endpointId - the endpoint id

userId - the user id (optional)

session - the session

Returns:

the connector

Throws:

ConnectorServiceException

getConnector

public Connector getConnector(String endpointId,
                              UserContext userContext,
                              javax.servlet.http.HttpSession session)
                       throws ConnectorServiceException

Retrieves a Connector for the given endpoint that is scoped to the given user context.

A user context is a means of wrapping the Credentials and ConnectorSession objects for a given user. If they are provided, then context will be drawn from them and stored back.

Parameters:

endpointId - the endpoint id

userContext - the user context

session - the http session

Returns:

the connector

Throws:

ConnectorServiceException

getAuthenticator

public Authenticator getAuthenticator(String id)
                               throws ConnectorServiceException

Returns the implementation of an Authenticator with a given id

Parameters:

id - the id

Returns:

the authenticator

Throws:

ConnectorServiceException

getConnectorSession

public ConnectorSession getConnectorSession(javax.servlet.http.HttpSession session,
                                            String endpointId)

Returns the ConnectorSession bound to the current HttpSession for the given endpoint

Parameters:

session - the session

endpointId - the endpoint id

Returns:

the connector session

removeConnectorSession

public void removeConnectorSession(javax.servlet.http.HttpSession session,
                                   String endpointId)

Removes the ConnectorSession from the HttpSession for the given endpoint

Parameters:

session - the session

endpointId - the endpoint id

getCredentialVault

public CredentialVault getCredentialVault(javax.servlet.http.HttpSession session,
                                          String userId)
                                   throws CredentialVaultProviderException

Retrieves the user-scoped CredentialVault for the given user If a vault doesn't yet exist, a vault of the default type will be instantiated

Parameters:

userId - the user id

Returns:

the credential vault

Throws:

CredentialVaultProviderException - the credential vault provider exception

getCredentialVault

public CredentialVault getCredentialVault(javax.servlet.http.HttpSession session,
                                          String userId,
                                          String vaultProviderId)
                                   throws CredentialVaultProviderException

Retrieves the user-scoped CredentialVault for the given user id and given vault id

Parameters:

userId - the user id

vaultProviderId - the vault provider id

Returns:

the credential vault

Throws:

CredentialVaultProviderException - the credential vault provider exception
