BucketElementMallocAllocator

Implements a malloc based BucketElement Allactor.

By default the class constructor checks the type of the Bucket elements (i.e, the values stored in the Map). If the element contains reference items (e.g class or an array) then on malloc allocations the class adds the elements to the GC scan range and removes them from the GC scan range on recycling.

This tracking of the objects can be explicitly disabled through passing the appropriate flag to the class constructor.

class BucketElementMallocAllocator : IAllocator (

Bucket

) {

import core.stdc.stdio : fputs, stderr;;

import core.stdc.stdlib : malloc, free, abort;;

void* allocate();

void deallocate(void* element);

class ParkingStack;

void parkElements(size_t n, void delegate(IParkingStack park) dg);

}
