Member Function Documentation

◆ allocate()

pointer allocate ( size_type  n,

inline

attempts to allocate a block of storage with a size large enough to contain n elements of member type value_type, and returns a pointer to the first element.

Definition at line 235 of file pool.hpp.

◆ deallocate()

size_type  n 
) const
