class PortPoolMemoryBlock : public iox::roudi::MemoryBlock

Public Functions

PortPoolMemoryBlock() noexcept = default

Todo:

the PortPool needs to be refactored to use a typed MemPool once that is done, the cTor needs a configuration similar to MemPoolCollectionMemoryProvider

~PortPoolMemoryBlock() noexcept
PortPoolMemoryBlock(const PortPoolMemoryBlock&) = delete
PortPoolMemoryBlock(PortPoolMemoryBlock&&) = delete
PortPoolMemoryBlock &operator=(const PortPoolMemoryBlock&) = delete
PortPoolMemoryBlock &operator=(PortPoolMemoryBlock&&) = delete
virtual uint64_t size() const noexcept override

This function provides the size of the required memory for the underlying data. It is needed for the MemoryProvider to calculate the total size of memory.

Note

The size of for all the ports

Returns:

the required memory as multiple of the alignment

virtual uint64_t alignment() const noexcept override

This function provides the alignment of the memory for the underlying data. This information is needed for the MemoryProvider.

Note

The memory alignment for the ports

Returns:

the alignment of the underlying data.

cxx::optional<PortPoolData*> portPool() const noexcept

This function enables the access to the PortPool.

Returns:

an optional pointer to the underlying type, cxx::nullopt_t if value is not initialized

Protected Functions

virtual void onMemoryAvailable(cxx::not_null<void*> memory) noexcept override

This function is called once the memory is available and is therefore the earliest possibility to use the memory.

Note

This will create the ports at the location memory points to

Parameters:

memory[in] pointer to a valid memory block, the same one that the memory() member function would return

virtual void destroy() noexcept override

The MemoryProvider calls this either when MemoryProvider::destroy is called or in its destructor.

Note

This function can be called multiple times. Make sure that the implementation can handle this.

Note

This will clean up the ports
