Method Detail

setHub

@Inject
public void setHub(IOHubProvider hub)

Inject the IOHubProvider

Parameters:

hub - the hub provider.

isOptIn

public boolean isOptIn()

Description copied from class: AgentProtocol

Allow experimental AgentProtocol implementations to declare being opt-in. Note that Jenkins.setAgentProtocols(Set) only records the protocols where the admin has made a conscious decision thus:

• if a protocol is opt-in, it records the admin enabling it
• if a protocol is opt-out, it records the admin disabling it

Implementations should not transition rapidly from opt-in -> opt-out -> opt-in. Implementations should never flip-flop: opt-in -> opt-out -> opt-in -> opt-out as that will basically clear any preference that an admin has set. This latter restriction should be ok as we only ever will be adding new protocols and retiring old ones.

Overrides:

isOptIn in class AgentProtocol

Returns:

true if the protocol requires explicit opt-in.

getDisplayName

public String getDisplayName()
