Context. Finding solutions to problems with an incomplete set of necessary data is a relevant problem in various applied research. In object-oriented programming, a similar problem arises when it is necessary to create a class object in the absence of some data regarding its initialization.
Objective. If there is enough data to solve a certain set of problems, it is advisable to create an object of the corresponding class. Problems arise when not all attributes of the created object have values. This can lead to errors in the operation of the object when calling methods that use undefined attributes. The aim of the work is to develop a mechanism that provides blocking of methods that are not ready to work, as well as their gradual unlocking as values for the attributes are defined.
Method. A mathematical model of the class is proposed, which allows distinguishing two subsets of attributes that do not have values at the time of creating the class object. A method has been developed that automatically converts the source class, adding a mechanism for locking/unlocking certain methods depending on the presence or absence of attribute values that these methods directly or indirectly use.
Result. The Class Transformer software product was created, which allowed a series of experiments to be conducted that confirmed the effectiveness of the research. The experiments showed a significant reduction in class conversion time compared to performing this work in the traditional way.
Conclusions. The proposed method for automated class conversion in conditions of incomplete attribute definition, which, on the one hand, allows you to start working with the object without waiting for the moment of complete data definition, and on the other hand, reduces the time for class conversion. The method can be used for various object-oriented programming languages
