Class StoreAdapterPlugin

java.lang.Object

com.unboundid.directory.sdk.broker.api.StoreAdapterPlugin

All Implemented Interfaces:

Configurable, ExampleUsageProvider, UnboundIDExtension

@Extensible
 @BrokerExtension
 @ThreadSafety(level=INTERFACE_THREADSAFE)
public abstract class StoreAdapterPlugin
extends java.lang.Object
implements UnboundIDExtension, Configurable, ExampleUsageProvider

This class defines an API that must be implemented by extensions that need to intercept operations processed by a Store Adapter. The API has pre-request methods to intercept and make changes to store adapter requests before they are processed by the Store Adapter, and corresponding post-request methods to intercept and make changes to the results returned by the Store Adapter. All SCIM attributes in this API refer to native Store Adapter attributes, not attributes in the external client SCIM schema.

The Store Adapter Plugin is defined in the configuration and then referenced by a Store Adapter configuration object.

Constructor Detail

StoreAdapterPlugin

public StoreAdapterPlugin()

Creates a new instance of this store adapter plugin. All implementations must include a default constructor, but any initialization should generally be done in the initializeStoreAdapterPlugin(com.unboundid.directory.sdk.broker.types.BrokerContext, com.unboundid.directory.sdk.broker.config.StoreAdapterPluginConfig, com.unboundid.util.args.ArgumentParser) method.

Method Detail

getExtensionName

public abstract java.lang.String getExtensionName()

Retrieves a human-readable name for this extension.

Specified by:

getExtensionName in interface UnboundIDExtension

Returns:

A human-readable name for this extension.

getExtensionDescription

public abstract java.lang.String[] getExtensionDescription()

Retrieves a human-readable description for this extension. Each element of the array that is returned will be considered a separate paragraph in generated documentation.

Specified by:

getExtensionDescription in interface UnboundIDExtension

Returns:

A human-readable description for this extension, or null or an empty array if no description should be available.

getExamplesArgumentSets

public java.util.Map<java.util.List<java.lang.String>,java.lang.String> getExamplesArgumentSets()

Retrieves a map containing examples of configurations that may be used for this extension. The map key should be a list of sample arguments, and the corresponding value should be a description of the behavior that will be exhibited by the extension when used with that configuration.

Specified by:

getExamplesArgumentSets in interface ExampleUsageProvider

Returns:

A map containing examples of configurations that may be used for this extension. It may be null or empty if there should not be any example argument sets.

defineConfigArguments

public void defineConfigArguments(com.unboundid.util.args.ArgumentParser parser)
                           throws com.unboundid.util.args.ArgumentException

Updates the provided argument parser to define any configuration arguments which may be used by this extension. The argument parser may also be updated to define relationships between arguments (e.g., to specify required, exclusive, or dependent argument sets).

Specified by:

defineConfigArguments in interface Configurable

Parameters:

parser - The argument parser to be updated with the configuration arguments which may be used by this extension.

Throws:

com.unboundid.util.args.ArgumentException - If a problem is encountered while updating the provided argument parser.

initializeStoreAdapterPlugin

public void initializeStoreAdapterPlugin(BrokerContext serverContext,
                                         StoreAdapterPluginConfig config,
                                         com.unboundid.util.args.ArgumentParser parser)
                                  throws java.lang.Exception

Initializes this store adapter plugin. Any initialization should be performed here. This method should generally store the BrokerContext in a class member so that it can be used elsewhere in the implementation.

The default implementation is empty.

Parameters:

serverContext - A handle to the server context for the server in which this extension is running. Extensions should typically store this in a class member.

config - The general configuration for this object.

parser - The argument parser which has been initialized from the configuration for this store adapter plugin.

Throws:

java.lang.Exception - If a problem occurs while initializing this store adapter plugin.

finalizeStoreAdapterPlugin

public void finalizeStoreAdapterPlugin()

This hook is called when the store adapter plugin is disabled or the Broker shuts down. Any clean-up of this store adapter plugin should be performed here.

The default implementation is empty.

preCreate

public void preCreate(StorePreCreateRequestContext context)
               throws com.unboundid.scim2.common.exceptions.ScimException

This method is called before an entry is created in the native data store.

Parameters:

context - The store adapter request context.

Throws:

preRetrieve

public void preRetrieve(StorePreRetrieveRequestContext context)
                 throws com.unboundid.scim2.common.exceptions.ScimException

This method is called before an entry is retrieved from the native data store in the following cases:

• To fetch an entry for a SCIM retrieve operation.
• To fetch an entry from a secondary store adapter for each primary store adapter entry obtained during a SCIM search.
• To fetch an entry from the primary store adapter for each secondary store adapter entry obtained when a SCIM search filter is processed by a secondary store adapter.

Parameters:

Parameters:

context - The store adapter request context.

Throws:

com.unboundid.scim2.common.exceptions.ScimException - If thrown, a corresponding SCIM ErrorResponse will be returned to the client.

preUpdate

public void preUpdate(StorePreUpdateRequestContext context)
               throws com.unboundid.scim2.common.exceptions.ScimException
