Detailed Description

template<typename MessageT, typename Alloc = std::allocator<void>>
class rclcpp::message_memory_strategy::MessageMemoryStrategy< MessageT, Alloc >

Default allocation strategy for messages received by subscriptions.

A message memory strategy must be templated on the type of the subscription it belongs to.
