List of trySetCount() Examples

Examples of trySetCount()

com.hazelcast.core.ICountDownLatch.trySetCount()
Sets the count to the given value if the current count is zero.
If count is not zero then this method does nothing and returns {@code false}. @param count the number of times {@link #countDown} must be invokedbefore threads can pass through {@link #await} @return {@code true} if the new count was set or {@code false} if the currentcount is not zero @throws IllegalArgumentException if {@code count} is negative
org.apache.curator.framework.recipes.shared.SharedCount.trySetCount()
Changes the shared count only if its value has not changed since this client last read it. If the count has changed, the value is not set and this client's view of the value is updated. i.e. if the count is not successful you can get the updated value by calling {@link #getCount()}. @deprecated use {@link #trySetCount(VersionedValue,int)} for stronger atomicityguarantees. Even if this object's internal state is up-to-date, the caller has no way to ensure that they've read the most recently seen count. @param newCount the new value to attempt @return true if the change attempt was successful, false if not. If the changewas not successful, {@link #getCount()} will return the updated value @throws Exception ZK errors, interruptions, etc.
org.redisson.core.RCountDownLatch.trySetCount()
Sets new count value only if previous count already has reached zero or not been setted at all. @param count the number of times {@link #countDown} must be invokedbefore threads can pass through {@link #await} @return true if new count settedfalse if previous count has not reached zero
