Type conversion

The type conversion operator creates a property that converts an object of one built-in class to an object of another built-in class. If type conversion is not possible, the property value will be NULL.

String and file types

String types can be converted to human-readable file types (CSVFILE, XMLFILE, JSONFILE, HTMLFILE, etc.), and vice versa - human-readable file types can be converted to string types.

info

Converting dynamic-type files (FILE) to strings and vice versa is prohibited in the current implementation, but if necessary this can be done via an intermediate human-readable type - for example, by first converting to CSVFILE, and only then to FILE (the resulting file will have the extension CSV)

Language

To implement conversion, the type conversion operator is used.

Examples

itemCount = DATA INTEGER (Store);
itemCountToString(s) = BPSTRING[10](itemCount(s));

barcode = DATA STRING[15] (Item);
longBarcode(Item i) = LONG(barcode(i));
