MapEnumerator.reset Method

Dynamics AX 2009

Dynamics AX 4.0

Moves the enumerator to point to immediately before the first element in the map.

public void reset()

Run On

Called

Remarks

The reset method moves the enumerator to the start of the set, before the first element in the set. You must call the MapEnumerator.moveNext method to make it point to the first element in the set.

Example

The following example reverse engineers the table definitions of all the tables in a project, and creates a UML class for each one. The tables in the project are contained in the projectTables map. The tables that are used by the tables in the project and the tables that use the tables in the project are also reverse engineered, and contained in the nonProjectTables map.

The MapEnumerator.reset method is used several times to reset the enumerators for the two maps, so that different information can be generated.
