Detailed Description

template<class Texec>
class DtParallelExecutionContainer< Texec >

DtParallelExecutionContainer is implementation of DtExecutionContainer which executes methods on all contained objects in parallel on multiple threads.

Note that objects of this class are not themselves threadsafe, so you can't add items to, or remove items from the collection in different threads.
