@sencha/extjs/no-private-method-override

Report the overriding of a private method

Rule Details

This rule will report when a private method is being overridden.

In this example, getAutoId is a private method of the Ext.Component Class and has been around since version 4. And getActiveCounter is a getter method generated by the framework because of the activeCounter config starting with version 5. A problem will be reported if the fromVersion is any version and the toVersion is set to any value >= 5.
