Detailed Description

template<typename T>
class os::rtos::memory::allocator_stateless_default_resource< T >

Standard allocator based on the RTOS system default memory manager.

Template Parameters

T	Type of elements to be allocated.

This class template is used as the default allocator for system classes. It gets memory from the system default memory manager os::rtos::memory::get_default_resource().

Note

As default allocator, this class must be stateless, i.e. have no member variables.
