public class TE_iterate

extends TemplateElement

Processes all child elements for each element of the collection obtained from evaluating the expr-attribute. For the child elements, the context is set to the corresponding element of the collection for each iteration. When a var attribute is given, the corresponding variable name is used as iterator variable instead of the evaluation context (self). The orderBy-attribute can be used to iterate over the elements ordered by the given OCL expression. The counter-attribute allows to declare an integer variable holding the current element index in each iteration.

Attributes

expr

Contains an OCL expression that must result in an collection. For each element of the resulting collection, the child elements of iterate are processed. If omitted, the current context must be a collection which is used for iteration

iterator

If present, the given variable name is used as iterator instead of self.

orderBy

If present, the given expression is used to determine the iteration ordering of the elements of the source collection.

inverse

If present and the value is true, the elements of the collection are iterated in inverse order.

counter

If present, the given variable name is used to declare an integer variable holding the current element index.
