// RAVEN STANDARD TEMPLATE LIBRARY
|
|
// (c) 2002 Activision
|
|
//
|
|
//
|
|
// Common
|
|
// ------
|
|
// The raven libraries contain a number of common defines, enums, and typedefs which
|
|
// need to be accessed by all templates. Each of these is included here.
|
|
//
|
|
// Also included is a safeguarded assert file for all the asserts in RTL.
|
|
//
|
|
// This file is included in EVERY TEMPLATE, so it should be very light in order to
|
|
// reduce compile times.
|
|
//
|
|
//
|
|
// Format
|
|
// ------
|
|
// In order to simplify code and provide readability, the template library has some
|
|
// standard formats. Any new templates or functions should adhere to these formats:
|
|
//
|
|
// - All memory is statically allocated, usually by parameter SIZE
|
|
// - All classes provide an enum which defines constant variables, including CAPACITY
|
|
// - All classes which moniter the number of items allocated provide the following functions:
|
|
// size() - the number of objects
|
|
// empty() - does the container have zero objects
|
|
// full() - does the container have any room left for more objects
|
|
// clear() - remove all objects
|
|
//
|
|
//
|
|
// - Functions are defined in the following order:
|
|
// Capacity
|
|
// Constructors (copy, from string, etc...)
|
|
// Range (size(), empty(), full(), clear(), etc...)
|
|
// Access (operator[], front(), back(), etc...)
|
|
// Modification (add(), remove(), push(), pop(), etc...)
|
|
// Iteration (begin(), end(), insert(), erase(), find(), etc...)
|
|
//
|
|
//
|
|
// NOTES:
