ConnectionImpl

public ConnectionImpl()

Application code should use Connection.Factory.create() instead.

Method Details

session

public SessionImpl session()

Description copied from interface: Connection

Returns a newly created session TODO does the Connection's channel-max property limit how many sessions can be created, or opened, or neither?

Specified by:

session in interface Connection

Specified by:

session in interface ProtonJConnection

addSessionEndpoint

protected org.apache.qpid.proton.engine.impl.LinkNode<SessionImpl> addSessionEndpoint(SessionImpl endpoint)

addLinkEndpoint

protected org.apache.qpid.proton.engine.impl.LinkNode<LinkImpl> addLinkEndpoint(LinkImpl endpoint)

sessionHead

public Session sessionHead(EnumSet<EndpointState> local,
 EnumSet<EndpointState> remote)

Description copied from interface: Connection

Returns the head of the list of sessions in the specified states. Typically used to discover sessions whose remote state has acquired particular values, e.g. sessions that have been remotely opened or closed. TODO what ordering guarantees on the returned "linked list" are provided?

Specified by:

sessionHead in interface Connection

See Also:

• Session.next(EnumSet, EnumSet)

linkHead

public Link linkHead(EnumSet<EndpointState> local,
 EnumSet<EndpointState> remote)

Description copied from interface: Connection

Returns the head of the list of links in the specified states. Typically used to discover links whose remote state has acquired particular values, e.g. links that have been remotely opened or closed.

Specified by:

linkHead in interface Connection

See Also:

• Link.next(EnumSet, EnumSet)

getConnectionImpl

protected ConnectionImpl getConnectionImpl()

Specified by:

getConnectionImpl in class EndpointImpl

getMaxChannels

public int getMaxChannels()

Specified by:

getMaxChannels in interface ProtonJConnection

getLocalContainerId

public String getLocalContainerId()

setLocalContainerId

public void setLocalContainerId(String localContainerId)

Specified by:

setLocalContainerId in interface ProtonJConnection

getWorkHead

public DeliveryImpl getWorkHead()

Description copied from interface: Connection

Returns the head of the delivery work list. The delivery work list consists of unsettled deliveries whose state has been changed by the other container and not yet locally processed.

Specified by:

getWorkHead in interface Connection

See Also:

• Receiver.recv(byte[], int, int)
• Delivery.settle()
• Delivery.getWorkNext()

setContainer

public void setContainer(String container)

Specified by:

setContainer in interface Connection

getContainer

public String getContainer()

Specified by:

getContainer in interface Connection

setHostname

public void setHostname(String hostname)

Description copied from interface: Connection

Set the name of the host (either fully qualified or relative) to which this connection is connecting to. This information may be used by the remote peer to determine the correct back-end service to connect the client to. This value will be sent in the Open performative. Note that it is illegal to set the hostname to a numeric IP address or include a port number.

Specified by:

setHostname in interface Connection

Parameters:

hostname - the RFC1035 compliant host name.

getRemoteContainer

public String getRemoteContainer()

Specified by:

getRemoteContainer in interface Connection

getRemoteHostname

public String getRemoteHostname()

Specified by:

getRemoteHostname in interface Connection

Specified by:

setOfferedCapabilities in interface Connection

setDesiredCapabilities

public void setDesiredCapabilities(Symbol[] capabilities)

Specified by:

setDesiredCapabilities in interface Connection

getRemoteOfferedCapabilities

public Symbol[] getRemoteOfferedCapabilities()

Specified by:

getRemoteOfferedCapabilities in interface Connection

getRemoteDesiredCapabilities

public Symbol[] getRemoteDesiredCapabilities()

Specified by:

getRemoteDesiredCapabilities in interface Connection

setProperties

public void setProperties(Map<Symbol,Object> properties)

Specified by:

setProperties in interface Connection

getRemoteProperties

public Map<Symbol,Object> getRemoteProperties()

Specified by:

getContext in interface Connection

Specified by:

getContext in interface Endpoint

Overrides:

getContext in class EndpointImpl

See Also:

• Endpoint.setContext(Object)

setContext

public void setContext(Object context)

Description copied from interface: Endpoint

Sets an arbitrary an application owned object on the end-point. This object is not used by Proton.

Specified by:

setContext in interface Connection

Specified by:

setContext in interface Endpoint

Overrides:

setContext in class EndpointImpl
