◆ finalize()

void LabelManager::finalize ( )

Creates symbol and relocation tables corresponding to input information.

All destinations must exist in TPEF before this method can be executed, otherwise finalize will throw exception. If exception is thrown finalize method will not do any changes to TPEF. When error that caused the exception is fixed, method can be re-executed and it continues from the same phase until the end.

Exceptions

CompileError There was problems during the resolving.
