Detailed Description

template<typename Alloc = std::allocator<void>>
class rclcpp::memory_strategies::allocator_memory_strategy::AllocatorMemoryStrategy< Alloc >

Delegate for handling memory allocations while the Executor is executing.

By default, the memory strategy dynamically allocates memory for structures that come in from the rmw implementation after the executor waits for work, based on the number of entities that come through.
