Detailed Description

Classes and functors that are necessary to request locks on an expression.

DataObjectRequest<RequestType> is defined for 4 request types here:

• WriteRequest: request a write lock
• ReadRequest: request a read lock
• WriteRelease: release a write lock
• ReadRelease: release a read lock
• CountBlocks: count the number of data objects in an array

DataObjectRequest is defined in Engine/DataObject.h. It acts as a PETE functor tag and as a tag that can be used by array's message function.
