GClasses::GHeap Class Reference

Provides a heap in which to put strings or whatever you need to store. If you need to allocate space for a lot of small objects, it's much more efficient to use this class than the C++ heap. Plus, you can delete them all by simply deleting the heap. You can't, however, reuse the space for individual objects in this heap. More...

char* GClasses::GHeap::add ( const char *  szString )

inline

Allocate space in the heap and copy a string to it. Returns a pointer to the string.

char* GClasses::GHeap::add ( const char *  pString, size_t  nLength  )

inline

Allocate space in the heap and copy a string to it. Returns a pointer to the string.

char* GClasses::GHeap::allocAligned ( size_t  nLength )

inline

Allocate space in the heap and return a pointer to it. The returned pointer will be aligned to start at a location divisible by the size of a pointer, so it will be suitable for use with placement new even on architectures that require aligned pointers.

char* GClasses::GHeap::allocate ( size_t  nLength )

inline

Allocate space in the heap and return a pointer to it.

void GClasses::GHeap::clear

(

)

Deletes all the blocks and frees up memory.
