LuciadLightspeedClass TLcyCompositeOWSTransport

java.lang.Object

com.luciad.lucy.util.TLcyGenericComposite<ILcdOWSTransport>

com.luciad.lucy.io.TLcyCompositeOWSTransport

All Implemented Interfaces:

ILcdOWSTransport, Iterable<ILcdOWSTransport>

public final class TLcyCompositeOWSTransport
extends TLcyGenericComposite<ILcdOWSTransport>
implements ILcdOWSTransport

Composite implementation (see composite design pattern) of ILcdOWSTransport. It keeps a list of associated ILcdOWSTransports: one can add and remove other ILcdOWSTransports to this ILcdOWSTransport.

When creating a new TLcyCompositeOWSTransport using the default constructor (see TLcyCompositeOWSTransport()), the created instance will only work on/with the ILcdOWSTransports registered on this composite instance (see TLcyGenericComposite.add(Object) and TLcyGenericComposite.remove(Object)).

When creating a new TLcyCompositeOWSTransport using the constructor specifying an ILcyLucyEnv instance (see TLcyCompositeOWSTransport(ILcyLucyEnv), the created instance will work on the Lucy back-end services. It will use all registered ILcdOWSTransport instances of the Lucy back-end, adding and/or removing an ILcdOWSTransport will add/remove the ILcdOWSTransport as service from Lucy, ... .

Constructor Detail

TLcyCompositeOWSTransport

public TLcyCompositeOWSTransport()

Create a new empty composite ILcdOWSTransport that will act on transports registered in this instance only.

TLcyCompositeOWSTransport

public TLcyCompositeOWSTransport(ILcyLucyEnv aLucyEnv)

Create a composite ILcdOWSTransport that will act on the transports registered in the Lucy back-end.

Parameters:

aLucyEnv - The Lucy back-end

Method Detail

performRequest

public TLcdOWSInputStream performRequest(TLcdOWSOperation aOWSOperation,
                                         ILcdOWSRequest aOWSRequest)
                                  throws TLcdOWSTransportException

Description copied from interface: ILcdOWSTransport

Performs the specified operation passing in the parameters defined in the request object.

Specified by:

performRequest in interface ILcdOWSTransport

Parameters:

aOWSOperation - the operation to perform

aOWSRequest - the request parameters

Returns:

a typed inputstream

Throws:

TLcdOWSTransportException - if an error occurs in the transport layer

isCompatibleURI

public boolean isCompatibleURI(URI aURI)

Description copied from interface: ILcdOWSTransport

Determines whether the specified URI is compatible with this transport. When performing a request, a transport implementation should only attempt to use those access points whose URIs are compatible.

Specified by:

isCompatibleURI in interface ILcdOWSTransport

Parameters:

aURI - the URI to test

Returns:

true if the specified URI is compatible; false otherwise

createDCP

public TLcdOWSDCP createDCP(URI aURI)

Description copied from interface: ILcdOWSTransport

Creates an OpenGIS Web Service DCP that can be used to access the specified URI using this transport. This method can be used to create a TLcdOWSOperation object that is needed to perform initial requests (in other words, requests that need to be performed before web service metadata has been retrieved).

Specified by:

createDCP in interface ILcdOWSTransport

Parameters:

aURI - the URI

Returns:

an OWS DCP object
