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

Report the calling of a private method

Rule Details

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

In this example, createWidget is a private method of the Ext Class and has been around since version 4. And _hasIcon is a private method of the Ext.button.Button Class and has been around since version 5. A problem will be reported when calling either of these methods when the fromVersion is >= 4 and the toVersion is set to any value >= 5.
