Interface ConnectionFactoryAdapter

All Superinterfaces:

Diagnosable

public interface ConnectionFactoryAdapter
extends Diagnosable

The connection factory adapter is responsible for creating and closing connections for a specific resource (such as, JDBC or JCA). When a connection is created, the connection factory adapter uses the information in the connection retrieval info object to create a connection. For example, if the resource is JDBC, the connection retrieval info object contains a user and password that the connection factory adapter uses to ask the JDBC resource for a connection.

Parameters:

connectionRequestInfo - The information to use to create the connection.

Returns:

A connection. null if a connection could not be created.

Throws:

UniversalConnectionPoolException - if an error occurs while creating the connection.

closeConnection

void closeConnection(java.lang.Object connection)
              throws UniversalConnectionPoolException

Closes the given connection.

Parameters:

connection - The connection to close.

Throws:

UniversalConnectionPoolException - if an error occurs while closing the connection.

createConnectionAsync

default java.util.concurrent.CompletionStage<java.lang.Object> createConnectionAsync(ConnectionRetrievalInfo cri,
                                                                                     java.util.concurrent.Executor executor)

Creates a connection asynchronously.

Parameters:

cri - The information to use to create the connection.

executor - executor for asynchronous operation

Returns:

completion stage for created connection (can return null or thrown exception)

Closes a connection asynchronously.

Parameters:

connection - Connection to close.

executor - executor for asynchronous operation

Returns:

completion stage for joining (or getting) an end of closure.

createPooledConnection
