The ITContainCvt interface
Base class: ITEssential
Decomposes an object into C++ base type instances. ITContainCvt is used by the ITContainerIter class to extract values from an object. ITContainCvt is to be used for objects that are naturally represented by base type arrays, such as a point list.
This interface provides the following methods.
| Method | Description |
|---|---|
| ITBool ConvertTo(long item, output_type &) | Converts item to the output type. The output_type
parameter must be one of the following types:
|
| long NumItems() | Returns the number of items in this object. |
| ITBool ConvertFrom (long item, const type) | Sets the value of the contained item from the value of the C++ type given as type. |
