Detailed Description

template<class T, class JAllocator_t>
class JLANG::JObjectAllocator< T, JAllocator_t >

Base class for customized new/delete operators.

The first template argument refers to the data type for new/delete operations and the second to the memory management class.

Possible syntax:

#include "JLang/JRAM.hh"

     class A : public JLANG::JObjectAllocator<A, JRAM> {
     };

In this case, the new/delete operations are implemented by the JLANG::JRAM class.
