Detailed Description

A descriptor for a buffer in which references can point.

Both locking and memory management happen at this granularity.

Constructor & Destructor Documentation

Member Data Documentation

m_delete

std::function<void()> PDI::Reference_base::Referenced_buffer::m_delete

The function to call to deallocate the buffer memory.

m_owners

int PDI::Reference_base::Referenced_buffer::m_owners

Number of references to this buffer.

m_read_locks

int PDI::Reference_base::Referenced_buffer::m_read_locks
