error_type that identifies the category of issue. Use these codes to filter, route, or display errors differently in your application.
Overview
mySpellChecker uses anErrorType enum to categorize detected errors. Each error type is a string value that describes the nature of the spelling or grammar issue.
Error Type Format
Error types are string constants defined inmyspellchecker.core.constants.ErrorType. Use them for filtering and handling specific error categories:
