setClassNameFilters Method @beta

Restrict iteration to changes for the given EC class names. That means the rows for changes from other EC classes will be skipped entirely and won't be visible through the reader.

setClassNameFilters(classNames: Set<string>): void

@throws if step has already been called and the reader successfully stepped at least once(i.e. returned true for a step() call) or if the native layer encounters an error while setting the filter.

Parameter Type Description
classNames Set<string> EC class names to include. The classNames should be in the full name format(i.e. "SchemaName:ClassName").
Note: Schema names and class names must be provided in the correct case for proper filtering. Derived classes are not automatically included, so they must be specified explicitly if needed.

Returns - void
