Macro Definition Documentation

piForeach

#define piForeach	(		i,
			c
	)

Macro for iterate any container.

Use this macros instead of standard "for" to get read/write access to each element of container. Pass direction is direct
Example:

PIVector<int> vec;
vec << 1 << 2 << 3;
piForeach (int & i, vec)
    cout << i << ", ";
// 1, 2, 3, 
piForeach (int & i, vec)
    i++;
piForeach (int & i, vec)
    cout << i << ", ";
// 2, 3, 4, 

piForeachC

#define piForeachC	(		i,
			c
	)

Macro for iterate any container only for read.

Use this macros instead of standard "for" to get read access to each element of container. Pass direction is direct
Example:

PIVector<int> vec;
vec << 1 << 2 << 3;
piForeachC (int & i, vec)
    cout << i << ", ";
// 1, 2, 3, 
piForeachC (int & i, vec)
    i++; // ERROR! const iterator

piForeachR

#define piForeachR	(		i,
			c
	)

Macro for iterate any container with reverse direction.

Use this macros instead of standard "for" to get read/write access to each element of container. Pass direction is reverse
Example:

PIVector<int> vec;
vec << 1 << 2 << 3;
piForeachR (int & i, vec)
    cout << i << ", ";
// 3, 2, 1, 
piForeachR (int & i, vec)
    i++;
piForeachR (int & i, vec)
    cout << i << ", ";
// 4, 3, 2, 

piForeachCR

#define piForeachCR	(		i,
			c
	)

Macro for iterate any container only for read with reverse direction.

Use this macros instead of standard "for" to get read access to each element of container. Pass direction is reverse
Example:

PIVector<int> vec;
vec << 1 << 2 << 3;
piForeachCR (int & i, vec)
    cout << i << ", ";
// 3, 2, 1, 
piForeachCR (int & i, vec)
    i++; // ERROR! const iterator

piBreak

#define piBreak

Macro for break from any piForeach* loop.

Warning

C++ ordinary "break" doesn`t work inside piForeach* loops! Always use "piBreak" instead!
