/*
|
|
The following macros are for use of locks together with exception handling.
|
|
A synchronized block is properly 'unlocked' even if an exception occures.
|
|
It is used this way:
|
|
|
|
SYNCHRONIZED(MyObject) {
|
|
THROW(MyException..);
|
|
}
|
|
END_SYNCHRONIZED;
|
|
|
|
Where MyObject must be an object that conforms to the NSObject and NSLocking
|
|
protocol.
|
|
This is much different to
|
|
|
|
[MyObject lock];
|
|
{
|
|
THROW(MyException..);
|
|
}
|
|
[MyObject unlock];
|
|
|
|
which leaves the lock locked when an exception happens.
