List of availablePermits() Examples

Examples of availablePermits()

com.hazelcast.core.ISemaphore.availablePermits()
Returns the current number of permits currently available in this semaphore.
- This method is typically used for debugging and testing purposes.
@return the number of permits available in this semaphore
java.util.concurrent.Semaphore.availablePermits()
Returns the current number of permits available in this semaphore.
This method is typically used for debugging and testing purposes. @return the number of permits available in this semaphore
org.menagerie.latches.spi.ZkSemaphore.availablePermits()
Gets the number of permits available at the time of invocation
Note that size estimates in a distributed environment are necessarily a moving target. This method is typically useful only for debugging and testing purposes, and should not be used for programmatic control flow. @return the number of permits available in this semaphore at the time of invocation
