In Magik generator methods are called iterator methods.
An iterator is a special object that lets you iterate over data.
Here's a simple example of direct iterator manipulation.
Returns an iterator to the element before beginning(public member function) edit.
Added support for non-scalar Iterator keys in foreach.
i.e. returning a slice from an iterator.
An iterator is invalidated only when the corresponding element is deleted.
creating a copy of a sequence or materialzing an iterator.
If no__iterator__ method is present, a default iterator is created.
any object that is implemented as an iterator.
The iterator for an object is found by calling the object's__iterator__ method.
If the new size is smaller than the old one: only erased elements and the past-the-end iterator If the new size is bigger than the old one:
An iterator may allow the container object to be modified without invalidating the iterator. .
The next() method advances the iterator and returns the value pointed to by the iterator.
An iterator class is usually designed in tight coordination with the corresponding container class.
only an iterator over the list; thus it is better for looping.
You can create an iterator for an object by calling Iterator(objectname);
called the iterator, which is pervasive.
Returns an iterator to the first element not less than the given key(public member function) edit.
Once you have an iterator, you can easily fetch the next item in the object by calling the iterator's next() method.
ForEach() is inherited iterator: scans the whole collection
To get an object's iterator from script, you should use Iterator(obj) rather than accessing the__iterator__ property directly.
For instance, once an iterator has advanced beyond the first element it may be possible to insert additional elements into the beginning of the container with predictable results.
An iterator can enforce additional restrictions on access,
There must also be a way to create an iterator so it points to some first element as well as some way to determine when the iterator has exhausted all of the elements in the container.
New iterator methods can be defined using the_iter and_loopbody statements:_iter_method my_object.
