Class LimitInfo

java.lang.Object

org.acemq.rabbitmq.admin.LimitInfo

public final class LimitInfo
extends Object

A limit on a virtual host or a user.

The controls that stop one misbehaving application taking a broker down for everybody: a connection leak that would otherwise reach the node's file descriptor limit, or a service declaring queues in a loop.

The broker returns these as a map because a vhost can carry several at once — the JSON is {"vhost":"/","value":{"max-connections":100,"max-queues":50}} rather than one object per limit.
