Class RemoteStore

java.lang.Object
  org.springframework.extensions.webscripts.AbstractStore
      org.springframework.extensions.webscripts.RemoteStore

All Implemented Interfaces:

Store

public class RemoteStore
extends AbstractStore

Store implementation that queries and retrieves documents from a remote HTTP endpoint.

The endpoint is assumed to support a WebScript Remote Store implementation (such as AVMRemoteStore) that mirrors the required Store API.

Constructor Detail

RemoteStore

public RemoteStore()

Method Detail

setConnectorService

public void setConnectorService(ConnectorService service)

Parameters:

service - The ConnectorService bean

getConnectorService

public ConnectorService getConnectorService()

Gets the connector service.

Returns:

the connector service

setConnectorProvider

public void setConnectorProvider(ConnectorProvider connectorProvider)

Sets the connector provider

getConnectorProvider

public ConnectorProvider getConnectorProvider()

Returns:

the connector provider

setApi

public void setApi(String api)

Parameters:

api - the WebScript API path to set for the remote store i.e. "/remotestore"

getApi

public String getApi()

Gets the api.

Returns:

the api

setPath

public void setPath(String path)

Sets the base path to send to the remote store

Parameters:

path -

setEndpoint

public void setEndpoint(String endpoint)

Parameters:

endpoint - the endpoint ID to use when calling the remote API

getEndpoint

public String getEndpoint()

Gets the endpoint.

Returns:

the endpoint

setWebappId

public void setWebappId(String webappId)

Sets the store's web application id to bind to within the designated store This is meaningful for WCM Web Project stores.

Parameters:

webappId -

getWebappPathPrefix

public String getWebappPathPrefix()

setWebappPathPrefix

public void setWebappPathPrefix(String webappPathPrefix)

getWebappId

public String getWebappId()

Gets the store's web application id binding This is meaningful for WCM Web Project stores.

Returns:

setStoreId

public void setStoreId(String storeId)

Allows for specification of default or fallback store id to use when binding to a remote store. This can be overridden by providing an implementation of a RemoteStoreContextProvider in the Spring Bean configuration.

Parameters:

storeId - the default store id

getStoreId

public String getStoreId()

Gets the store id.

Returns:

the store id

getStorePath

public String getStorePath()

Store path calculation If we have a store context, then we can check to see if a base path should be inserted ahead of the path that we believe we're directing to. Use case - consider writing a file /alfresco/site-data/components/component.xml If we're writing to sitestore, then the file is stored relative to the store root. In the case of a WCM web project, however, we may want to persist to one of several web applications. If we have a webappId (retrieved from the context), then we prepend: /WEB-INF/classes The new location is: /WEB-INF/classes/alfresco/site-data/components/component.xml This allows us to operate against both straight up AVM stores as well as WCM Web Project AVM stores.

Returns:

init

public void init()

Description copied from interface: Store

Initialise Store (called once)

isSecure

public boolean isSecure()

Description copied from interface: Store

Returns true if this store is considered secure - i.e. on the app-server classpath. Scripts in secure stores can be run under the identity of a declared user (via the runas attribute) rather than the authenticated user.

Returns:

true if this store is considered secure
