Dynamic validation framework extension

A system comprising:

• one or more processors;
• and
• one or more memory devices comprising instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• receiving, at a programming language framework, an instance of an object,
• wherein a definition of the object is annotated with a constraint;
• receiving, at the programming language framework, one or more validators that are annotated with an annotation that identifies an attribute in the definition of the object and a value for the attribute, wherein the programming language framework comprises a definition of an abstract class from which each of the one or more validators is inherited, and the abstract class comprises a protected function that validates an object against custom constraints;
• identifying, at the programming language framework, a validator in the one or more validators for which a value of the attribute in the instance of the object matches the value for the attribute in the annotation of the validator;
• and
• executing the validator using the instance of the object.

A method of executing dynamic validation in programming language frameworks, the method comprising:

• receiving, at a programming language framework, an instance of an object, wherein a definition of the object is annotated with a constraint;
• receiving, at the programming language framework, one or more validators that are annotated with an annotation that identifies an attribute in the definition of the object and a value for the attribute, wherein the programming language framework comprises a definition of an abstract class from which each of the one or more validators is inherited, and the abstract class comprises a protected function that validates an object against custom constraints;
• identifying, at the programming language framework, a validator in the one or more validators for which a value of the attribute in the instance of the object matches the value for the attribute in the annotation of the validator;
• and
• executing the validator using the instance of the object.
