Module cRowIdArray.pkg

cRowIdArray.pkg Class: cRowIdArray This is a private class that is used by db-grid classes (dbGrid & dbList - code in datalist.pkg) to store Rowids for each row in the grid. None of these messages in this class should ever be directly accessed from any of the developer's classes or objects. There should be public messages in the db-grid classes to do whatever a developer needs to do. Directly using these messages can result in instabilities. This class is private. It's existance, implementation and interface is likely to change. If a developer finds that they need a similar type of capability (a set class that stores and retrieves an array of Rowids) they may wish to use this class as a model for creating their own custom class. It is quite simple. All we are doing is serializing every value coming into the object and deserializing every value coming out of the object. This is needed because the array class cannot store rowId data-types. (Note that the native array data-type, could do this.)
