PropertyHandle :: CheckData - Check data in object instance(s)

The function checks the data in the object instance or collection. Data is checked for the selected instance in case an instance is selected in the property handle. When no instance is selected, data is checked for all instances in the collection.

When check performed well (without errors), the function returns false (no error). In case of errors reported in the protocol string the function returns true (errors found). When severe errors caused the function to terminate, the function returns 2 .

The result of the check process is returned in the string object passed to the function.
