doStart

protected void doStart(org.openremote.model.Container container)
                throws Exception

Description copied from class: AbstractProtocol

Start this protocol instance

Specified by:

doStart in class AbstractProtocol<SNMPAgent,SNMPAgentLink>

Throws:

Exception

Specified by:

doStop in class AbstractProtocol<SNMPAgent,SNMPAgentLink>

Throws:

Exception

doLinkAttribute

protected void doLinkAttribute(String assetId,
 org.openremote.model.attribute.Attribute<?> attribute,
 SNMPAgentLink agentLink)
                        throws RuntimeException

Description copied from class: AbstractProtocol

Link an Attribute to its linked Agent.

Specified by:

doLinkAttribute in class AbstractProtocol<SNMPAgent,SNMPAgentLink>

Throws:

RuntimeException

doUnlinkAttribute

protected void doUnlinkAttribute(String assetId,
 org.openremote.model.attribute.Attribute<?> attribute,
 SNMPAgentLink agentLink)

Description copied from class: AbstractProtocol

Unlink an Attribute from its linked Agent.

Specified by:

doUnlinkAttribute in class AbstractProtocol<SNMPAgent,SNMPAgentLink>

doLinkedAttributeWrite

protected void doLinkedAttributeWrite(SNMPAgentLink agentLink,
 org.openremote.model.attribute.AttributeEvent event,
 Object processedValue)

Description copied from class: AbstractProtocol

An Attribute event (write) has been requested for an attribute linked to this protocol. The processedValue is the resulting value after applying standard outbound value processing (see ProtocolUtil.doOutboundValueProcessing(org.openremote.model.attribute.AttributeRef, org.openremote.model.asset.agent.AgentLink<?>, java.lang.Object, boolean, java.time.Instant)). Protocol implementations should generally use the processedValue but may also choose to use the original value for some purpose if required.

Specified by:

doLinkedAttributeWrite in class AbstractProtocol<SNMPAgent,SNMPAgentLink>
