Detailed Description

template<int t_SIZE>
class bdlma::LocalSequentialAllocator< t_SIZE >

This class implements the ManagedAllocator protocol to provide a fast allocator that dispenses heterogeneous blocks of memory (of varying, user-specified sizes) from a local buffer whose capacity is the specified t_SIZE (in bytes). If an allocation request exceeds the remaining free memory space in the local buffer, memory will be supplied by an (optional) allocator supplied at construction; if no allocator is supplied, the currently installed default allocator is used. This class is exception neutral; if memory cannot be allocated, the behavior is defined by the (optional) allocator supplied at construction.
