Generating a 1C BSL method interceptor creates &Перед, &После, or &ИзменениеИКонтроль handlers for borrowed object methods in CFE extensions. It automatically locates the target module .bsl file using deterministic mapping, reads the NamePrefix from Configuration.xml, and writes the hooking code in UTF-8 format.

The best way to inject logic before or after a method call in 1C CFE is to generate a &Перед (Before) or &После (After) handler. The skill appends this BSL code directly into the target extension module file, automatically applying the correct NamePrefix from Configuration.xml.

ModificationAndControl interception in BSL works by replacing a borrowed object's method body using the &ИзменениеИКонтроль directive. The generated interceptor can optionally add a Возврат statement for functions, allowing you to fully override or wrap the original method's execution flow.

Yes, you can replace a function body in a 1C extension by generating an &ИзменениеИКонтроль interceptor. When the IsFunction parameter is enabled, the generated BSL code automatically includes the Возврат statement to ensure the overriding function returns a value correctly.

No, you do not need to manually find the target .bsl file. The process uses deterministic mapping of ModulePath combined with ExtensionPath to automatically locate the correct module file within the CFE structure, then writes the BSL code by creating or appending to that file.

A NamePrefix is required for 1C extension method interceptors to ensure the generated procedure does not conflict with existing methods in the configuration. The prefix is automatically read from Configuration.xml and applied to the interceptor procedure name within the target module.
