Interface Barrier

public interface Barrier

Barriers serve as synchronization points for groups of threads that must occasionally wait for each other. Barriers may support any of several methods that accomplish this synchronization. This interface merely expresses their minimal commonalities:

[ Introduction to this package. ]

Method Summary
booleanbroken()
Returns true if the barrier has been compromised by threads leaving the barrier before a synchronization point (normally due to interruption or timeout).
intparties()
Return the number of parties that must meet per barrier point.

Method Detail

broken

public boolean broken()
Returns true if the barrier has been compromised by threads leaving the barrier before a synchronization point (normally due to interruption or timeout). Barrier methods in implementation classes throw throw BrokenBarrierException upon detection of breakage. Implementations may also support some means to clear this status.

parties

public int parties()
Return the number of parties that must meet per barrier point. The number of parties is always at least 1.
