void Jitrino.CompilationInterface.lockMethodData

(

void

)

Acquires a lock to protect method's data modifications (i.e.

code/info block allocations, exception handlers registration, etc) in multi-threaded compilation. The lock *must not* surround a code which may lead to execution of managed code, or a race and hang happen. For example, the managed code execution may happen during a resolution (invocation of resolve_XXX) to locate a class through a custom class loader. Note, that the lock is *not* per-method, and shared across all the methods.

void Jitrino.CompilationInterface.unlockMethodData

(

void

)

Releases a lock which protects method's data.
