What signifies Patternist's iterators is that they + * almost always contains business logic(which is the cause to their + * efficiency). + * + * An example which illustrates this principle is the RangeIterator. When + * the RangeExpression is told to create a sequence of integers between 1 + * and 1000, it doesn't enter a loop that allocates 1000 Integer instances, + * but instead return an RangeIterator that incrementally creates the + * numbers when asked to do so via its RangeIterator::next() function. If + * it turns out that the expression that has the range expression as + * operand only needs three items from it, that is what gets created, not + * 1000. + * + * All iterators operates by that principle, perhaps suitably labeled as + * "pull-based", "lazy loaded" or "serialized". Central for the XPath + * language is that it filters and selects data, and the iterators supports + * this well by letting the demand of the filter expressions(the callees) + * decide how "much" source that gets computed. In this way the evaluation + * of an expression tree can lead to a chain of pipelined iterators, where + * the first asks the second for data and then performs its specific + * operations, the second subsequently asks the third, and so forth. + * + * However, the iterators are not limited to be used for representing + * sequences of items in the XPath Data Model. The Iterator is + * parameterized on one argument, meaning any type of "units" can be + * iterated, be it Item or any other. One use of this is in the + * ExpressionSequence(which implements the comma operator) where it creates + * Iterator instances over Expression instances -- its operands.
