Package org.forgerock.json.resource

Class AbstractConnectionWrapper<C extends Connection>

java.lang.Object
org.forgerock.json.resource.AbstractConnectionWrapper<C>
Type Parameters:
C - The type of wrapped connection.
All Implemented Interfaces:
Closeable, AutoCloseable, Connection, org.forgerock.services.descriptor.Describable<org.forgerock.api.models.ApiDescription,Request>
public abstract class AbstractConnectionWrapper<C extends Connection> extends Object implements Connection, org.forgerock.services.descriptor.Describable<org.forgerock.api.models.ApiDescription,Request>
An abstract base class from which connection wrappers may be easily implemented. The default implementation of each method is to delegate to the wrapped connection.

  • Field Details

    • connection

      protected final C extends Connection connection
      The wrapped connection.

  • Constructor Details

    • AbstractConnectionWrapper

      protected AbstractConnectionWrapper(C connection)
      Creates a new connection wrapper.
      Parameters:
      connection - The connection to be wrapped.

  • Method Details

    • transform

      protected org.forgerock.services.context.Context transform(org.forgerock.services.context.Context context)
      Optional Context-transformation function if the implementer has requirements to override the Context provided in the Connection's method invocations.

      The default implementation is a pass-through no-op.

      Parameters:
      context - the request context
      Returns:
      the transformed context

    • action

      public ActionResponse action(org.forgerock.services.context.Context context, ActionRequest request) throws ResourceException
      Performs an action against a specific resource, or set of resources. Bulk updates are an example of an action request.

      The default implementation is to delegate.

      Specified by:
      action in interface Connection
      Parameters:
      context - The request context, such as associated principal.
      request - The action request.
      Returns:
      A JSON object containing the result of the action, the content of which is specified by the action.
      Throws:
      ResourceException - If the action could not be performed.

    • actionAsync

      public Promise<ActionResponse,ResourceException> actionAsync(org.forgerock.services.context.Context context, ActionRequest request)
      Asynchronously performs an action against a specific resource, or set of resources. Bulk updates are an example of an action request.

      The default implementation is to delegate.

      Specified by:
      actionAsync in interface Connection
      Parameters:
      context - The request context, such as associated principal.
      request - The action request.
      Returns:
      A future representing the result of the request.

    • close

      public void close()
      Releases any resources associated with this connection. For physical connections to a server this will mean that the underlying socket is closed.

      Other connection implementations may behave differently. For example, a pooled connection will be released and returned to its connection pool.

      Calling close on a connection that is already closed has no effect.

      The default implementation is to delegate.

      Specified by:
      close in interface AutoCloseable
      Specified by:
      close in interface Closeable
      Specified by:
      close in interface Connection

      Specified by:
      create in interface Connection
      Parameters:
      context - The request context, such as associated principal.
      request - The create request.
      Returns:
      The newly created JSON resource.
      Throws:
      ResourceException - If the JSON resource could not be created.

    • createAsync

      public Promise<ResourceResponse,ResourceException> createAsync(org.forgerock.services.context.Context context, CreateRequest request)

    • isClosed

      public boolean isClosed()
      Indicates whether or not this connection has been explicitly closed by calling close. This method will not return true if a fatal error has occurred on the connection unless close has been called.

      The default implementation is to delegate.

      Specified by:
      isClosed in interface Connection
      Returns:
      true if this connection has been explicitly closed by calling close, or false otherwise.
