Constructor Detail

ServiceRecord

public ServiceRecord()

Create a service record with no ID, description or registration time. Endpoint lists are set to empty lists.

ServiceRecord

public ServiceRecord(ServiceRecord that)

Deep cloning constructor

Parameters:

that - service record source

addExternalEndpoint

public void addExternalEndpoint(Endpoint endpoint)

Add an external endpoint

Parameters:

endpoint - endpoint to set

addInternalEndpoint

public void addInternalEndpoint(Endpoint endpoint)

Add an internal endpoint
