Method Detail

createTransport

public Transport createTransport(URI remoteURI)
                          throws Exception

Creates an instance of the given Transport and configures it using the properties set on the given remote broker URI.

Parameters:

remoteURI - The URI used to connect to a remote Peer.

Returns:

a new Transport instance.

Throws:

Exception - if an error occurs while creating the Transport instance.

doCreateTransportOptions

protected TransportOptions doCreateTransportOptions()

Create and return an instance of TransportOptions appropriate for the Transport type that this factory will return.

Returns:

a newly allocated TransportOptions instance appropriate to the factory.

applyTransportConfiguration

protected TransportOptions applyTransportConfiguration(TransportOptions transportOptions,
                                                       Map<String,String> transportURIOptions)

Apply URI options to a freshly created TransportOptions instance which will be used when the actual Transport is created.

Parameters:

transportOptions - The TransportOptions instance to configure.

transportURIOptions - The URI options to apply to the given TransportOptions.

Returns:

doCreateTransport

protected abstract Transport doCreateTransport(URI remoteURI,
                                               TransportOptions transportOptions)
                                        throws Exception

Create the actual Transport instance for this factory using the provided URI and TransportOptions instances.

Parameters:

remoteURI - The URI used to connect to a remote Peer.

transportOptions - The TransportOptions used to configure the new Transport.

Returns:

a newly created and configured Transport instance.

Throws:

Exception - if an error occurs while creating the Transport instance.

getName

public abstract String getName()

Returns:

the name of this Transport.

isSecure

public boolean isSecure()

Returns:

true if the Transport that this factory provides uses a secure channel.

create

public static Transport create(String transportKey,
                               URI remoteURI)
                        throws Exception

Static create method that performs the TransportFactory search and handles the configuration and setup.

Parameters:

transportKey - The transport type name used to locate a TransportFactory.

remoteURI - the URI of the remote peer.

Returns:

a new Transport instance that is ready for use.

Throws:

Exception - if an error occurs while creating the Transport instance.

findTransportFactory

public static TransportFactory findTransportFactory(String transportKey)
                                             throws IOException

Searches for a TransportFactory by using the scheme from the given key. The search first checks the local cache of Transport factories before moving on to search in the class-path.

Parameters:

transportKey - The transport type name used to locate a TransportFactory.

Returns:

a Transport factory instance matching the transport key.

Throws:

IOException - if an error occurs while locating the factory.
