Detailed Description

Click here to see the header.

This header defines the fundamental list operations.

NOTE: The internal representation of lists is hidden. Although there aren't compelling reasons to change the representation, you should avoid writing code that depends on the internal representation details.

#define BOOST_PP_LIST_CONS (  H,
T    ) 
 

List constructor.

Lists are build using list constructors BOOST_PP_LIST_NIL and BOOST_PP_LIST_CONS(). For example, 

  BOOST_PP_LIST_CONS(1,
  BOOST_PP_LIST_CONS(2,
  BOOST_PP_LIST_CONS(3,
  BOOST_PP_LIST_CONS(4,
  BOOST_PP_LIST_CONS(5,
  BOOST_PP_LIST_NIL)))))

Short lists can also be build from tuples: 

  BOOST_PP_TUPLE_TO_LIST(5,(1,2,3,4,5))

Both of the above lists contain 5 elements: 1, 2, 3, 4 and 5.

#define BOOST_PP_LIST_FIRST (  L    ) 
 

Expands to the first element of the list. The list must not be nil.

For example, 

  BOOST_PP_LIST_FIRST(BOOST_PP_TUPLE_TO_LIST(5,(1,2,3,4,5)))

expands to 1.

See BOOST_PP_LIST_REST().

#define BOOST_PP_LIST_IS_CONS (  L    ) 
 

Expands to 1 if the list is not nil and 0 otherwise.

See BOOST_PP_LIST_IS_NIL().

#define BOOST_PP_LIST_IS_NIL (  L    ) 
 

Expands to 1 if the list is nil and 0 otherwise.

See BOOST_PP_LIST_IS_CONS().

#define BOOST_PP_LIST_NIL
 

List nil constructor.

See BOOST_PP_LIST_CONS().

#define BOOST_PP_LIST_REST (  L    ) 
 

Expands to a list of all but the first element of the list. The list must not be nil.

For example, 

  BOOST_PP_LIST_REST(BOOST_PP_TUPLE_TO_LIST(5,(1,2,3,4,5)))

expands to a list containing 2, 3, 4 and 5.

See BOOST_PP_LIST_FIRST().
