Detailed Description

Class for implementing R_alloc() and kindred functions.

This class has only static members. It implements a stack of pointers to blocks of memory.

Member Function Documentation

void * RAllocStack::allocate ( size_t sz )

static

Allocate a new block of memory.

The block will be aligned on a multiple of sizeof(double) .

Parameters:

sz	The required size in bytes (strictly, as a multiple of `sizeof(char)`), of the memory block.

void RAllocStack::restoreSize ( size_t new_size )

static

Restore stack to a previous size.

Restore the stack to a previous size by popping elements off the top.

Parameters:

new_size The size to which the stack is to be restored. Must not be greater than the current size.

Note:: In future this method may cease to be available, since the use of the RAllocStack::Scope class is preferable.

static size_t CXXR::RAllocStack::size ( )

inlinestatic

Current size of stack.

Note:: This method is intended for use in conjunction with restoreSize(), and may cease to be public in future.
