a string describing the resource that is protected, e.g. "mysql:server-b.com:3336". It is used in exceptions and visible through JMX.
a simple describing identifier that is unique per sentry chain, e.g. "rateLimit".
ResourceName
plus sentryType
uniquely name each sentry. The sentry registry
enforces this. The sentryType
is also used in JMX to uniquely name bean properties
for a resource.
null
for sentry wrappers, that must not be registered.
A sentry that limits the number of concurrent invocations. A new instance can be obtained through the nl.grons.sentries.SentrySupport mixin.
The goal of a concurrency limiter is to prevent overloading of a shared resource. This sentry can be used as an alternative to a pool for easy to crate objects.
