Name
Monitor
Synopsis
This class contains static methods for thread communication
and synchronization. The
Enter()
and
Exit()
methods
allow you to obtain and release a lock on an object,
respectively. If an object lock has already been obtained by
another thread,
Enter()
blocks and
resumes executing when the lock is released.
Various languages have the ability to silently emit calls on this type
as language built-in primitives.
C#’s lock{}
syntax translates into these
two methods: the beginning of the lock
block is
transformed into a call to Enter()
,
and the close of the block calls
Exit()
. (In the presence of
exceptions and return calls, the C# compiler must ensure the release of
the monitor regardless of how the code exits the lock
block.)
TryEnter()
attempts to obtain an object lock,
but it continues executing and returns false if unsuccessful.
Wait()
releases an object lock and causes the
current thread to wait until another thread calls
Pulse()
or PulseAll()
on the
same object. Wait()
must be executed from a
synchronized block of code.
