LeaderResource - Class in org.kiwiproject.curator.leader.resource

JAX-RS resource providing endpoints for checking leadership and participant information.

LeaderResource(ManagedLeaderLatch) - Constructor for class org.kiwiproject.curator.leader.resource.LeaderResource

M

ManagedLeaderLatch - Class in org.kiwiproject.curator.leader

Wrapper around Curator's LeaderLatch which standardizes the id and latch path in ZooKeeper, and which registers with Dropwizard so that it manages the lifecycle (mainly to ensure the latch is stopped when the Dropwizard app stops).

ManagedLeaderLatch(CuratorFramework, String, String, LeaderLatchListener...) - Constructor for class org.kiwiproject.curator.leader.ManagedLeaderLatch

Construct a latch with a specific ID and standard latch path.

ManagedLeaderLatch(CuratorFramework, ServiceDescriptor, LeaderLatchListener...) - Constructor for class org.kiwiproject.curator.leader.ManagedLeaderLatch

Construct a latch with a standard ID and latch path.

ManagedLeaderLatchCreator - Class in org.kiwiproject.curator.leader

Entry point to initialize ManagedLeaderLatch, which wraps an Apache Curator LeaderLatch and allows for easy determination whether a JVM process is the leader in a group of JVMs connected to a ZooKeeper cluster.

ManagedLeaderLatchException - Exception in org.kiwiproject.curator.leader.exception

Exception that is thrown when there is some unexpected error relating to a managed Curator leader latch.

S

ServiceDescriptor - Class in org.kiwiproject.curator.leader

Value class that contains metadata about a service that participates in a leader latch.

ServiceDescriptor() - Constructor for class org.kiwiproject.curator.leader.ServiceDescriptor

start() - Method in class org.kiwiproject.curator.leader.ManagedLeaderLatch

Starts the latch, possibly creating non-existent znodes in ZooKeeper first.

start() - Method in class org.kiwiproject.curator.leader.ManagedLeaderLatchCreator

Starts the leader latch, performing the following actions: Creates a new ManagedLeaderLatch, starts it, and tells the Dropwizard lifecycle to manage (stop) it Creates and registers a ManagedLeaderLatchHealthCheck unless explicitly disabled via ManagedLeaderLatchCreator.withoutHealthCheck() Creates and registers the JAX-RS REST endpoints unless explicitly disabled via ManagedLeaderLatchCreator.withoutResources()

start(CuratorFramework, Environment, ServiceDescriptor, LeaderLatchListener...) - Static method in class org.kiwiproject.curator.leader.ManagedLeaderLatchCreator

If you want a ManagedLeaderLatch and you want the standard options (a health check and JAX-RS REST resources) and you might need references to them, use this method to create and start a latch.

startLeaderLatch(CuratorFramework, Environment, ServiceDescriptor, LeaderLatchListener...) - Static method in class org.kiwiproject.curator.leader.ManagedLeaderLatchCreator

If the only thing you want is a ManagedLeaderLatch and you want the standard options (a health check and JAX-RS REST resources) and you do not need references to them, use this method to create and start a latch.

Stops the latch.

T

toString() - Method in class org.kiwiproject.curator.leader.ManagedLeaderLatch

W

whenLeader(Runnable) - Method in class org.kiwiproject.curator.leader.ManagedLeaderLatch

Perform the given action synchronously only if this latch is currently the leader.

whenLeader(Supplier<T>) - Method in class org.kiwiproject.curator.leader.ManagedLeaderLatch

Perform the given action defined by resultSupplier synchronously only if this latch is currently the leader, returning the result of resultSupplier.
