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));
