Sergey Evdokimov commented on IGNITE-59:
----------------------------------------

Text from mail conversation:

Sergey E: Will we support lockAsync() on IgniteCache? Should I remove all tests that check
lockAsync() methods?
Dmitriy: We should support it through our standard async support. I will take a closer look
at the design and will provide more detail.


Sergey E: Will be exists GridCacheEntry.isLocked() , GridCacheEntry.isLockedByThread() ? If
true we need the method to get entry by key on IgniteCache (analog of GridCacheProjection.entry(K
key)). 
Dmitriy: These methods will not exist on GridCacheEntry.


Sergey E: In current IgniteCache interface lock() returns java.util.concurrent.locks.Lock
. May be 'lock()' should return something like CacheLock, that extends java.util.concurrent.locks.Lock
and contains additional methods like "isLocked()", "isLockedByThread()". Thoughts?   Now IgniteCache
contains "isLocked(key)", "isLockedByThread(keys)" methods.


Sergey E: Why lockAll(Set) take a Set, may be it should take Collection ?
