function VariableAnalysisSniff::processVariableAsStaticMember

* Process a variable that is being accessed with static syntax. * * That is, this will record the use of a variable of the form * `MyClass::$myVariable` or `self::$myVariable`. * * Can be called for any token and will return false if the variable is not * of this type. * *

Parameters

File $phpcsFile: * @param int $stackPtr * * @return bool
