Detailed Description

Traversal allows to traverse elements of containers in an uniform way.

Traversal is not a meta-object, it is rather an abstraction for types wrapping various methods of container element traversal. Instances of these types are created by the MetaTraversal meta-object and allow the users to iterate through the elements of an arbitrary container in a generic way.

bool mirror::Traversal::done

(

void

)

const

Indicates that the element traversal is finished.

When this member function returns true, then the step_front and the front member functions must not be called.

empty

SafeLocator mirror::Traversal::front

(

void

)

const

Returns a locator for the current element in the traversal.

This function should not be called if done() returns true.

See also:

done

void mirror::Traversal::step_front

(

void

)

Moves the front of the range one step ahead, to the next element.

This function should not be called if done() returns true.
