Class SemaphoreHolder

java.lang.Object
  com.atlassian.confluence.search.contentnames.SemaphoreHolder

public class SemaphoreHolder
extends java.lang.Object

Holds the semaphore used to enforce a limit on the number of simultaneous quick nav searches. The purpose of this holder is to front the actual semaphore that does all the work. We need a front so as to have the ability to swap in another semaphore when the user decides to change the default limit. This is because we cannot increase the number of permits on the JDK Semaphore class.
