Constructor and Description
LocalBrokerData()
LocalBrokerData(String webServiceUrl, String webServiceUrlTls, String pulsarServiceUrl, String pulsarServiceUrlTls) Broker data constructor which takes in four URLs to satisfy the contract of ServiceLookupData.
LocalBrokerData(String webServiceUrl, String webServiceUrlTls, String pulsarServiceUrl, String pulsarServiceUrlTls, Map<String,AdvertisedListener> advertisedListeners)

Method Summary

Modifier and Type	Method and Description
void	cleanDeltas()
boolean	equals(Object o) Since the broker data is also used as a lock for the broker, we need to have a stable comparison operator that is not affected by the actual load on the broker.

                       String pulsarServiceUrl,
                       String pulsarServiceUrlTls)

Broker data constructor which takes in four URLs to satisfy the contract of ServiceLookupData.

LocalBrokerData

public LocalBrokerData(String webServiceUrl,
                       String webServiceUrlTls,
                       String pulsarServiceUrl,

                       Map<String,AdvertisedListener> advertisedListeners)

Method Detail

equals

public boolean equals(Object o)

Since the broker data is also used as a lock for the broker, we need to have a stable comparison operator that is not affected by the actual load on the broker.

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

update

public void update(SystemResourceUsage systemResourceUsage,
                   Map<String,NamespaceBundleStats> bundleStats)

Using the system resource usage and bundle stats acquired from the Pulsar client, update this LocalBrokerData.

Parameters:

systemResourceUsage - System resource usage (cpu, memory, and direct memory).

bundleStats - The bundle stats retrieved from the Pulsar client.

update

public void update(LocalBrokerData other)

Using another LocalBrokerData, update this.

Parameters:

other - LocalBrokerData to update from.
