Examples description

ZPub

Declares a resource with a path and a publisher on this resource. Then puts a value using the numerical resource id. The path/value will be received by all matching subscribers, for instance the ZSub example.

Usage:

./gradle ZPub

ZSub

Creates a subscriber with a key expression. The subscriber will be notified of each put made on any key expression matching the subscriber's key expression, and will print this notification.

Usage:

./gradle ZSub

ZGet

Sends a query message for a selector. The queryables with a matching path or selector (for instance ZQueryable) will receive this query and reply with paths/values that will be received by the query callback.

./gradle ZGet

ZPut

Puts a path/value into Zenoh. The path/value will be received by all matching subscribers, for instance the ZSub.

Usage:

./gradle ZPut

ZDelete

Performs a Delete operation into a path/value into Zenoh.

Usage:

./gradle ZDelete

ZQueryable

Creates a queryable function with a key expression. This queryable function will be triggered by each call to a get operation on zenoh with a selector that matches the key expression, and will return a value to the querier.

Usage:

./gradle ZQueryable

ZPubThr & ZSubThr

Pub/Sub throughput test. This example allows to perform throughput measurements between a publisher performing put operations and a subscriber receiving notifications of those puts.

Subscriber usage:

./gradle ZSubThr

Publisher usage:

./gradle ZPubThr
