All Implemented Interfaces:

Configurable, Contextualizable

public class IllegalTokenCheck

extends Check

Checks for illegal tokens.

Rational: Certain language features are often lead to hard to maintain code or are non-obvious to novice developers. Others may be discouraged in certain frameworks, such as not having native methods in EJB components.

An example of how to configure the check is:

 <module name="IllegalToken"/>
 

An example of how to configure the check to forbid a LITERAL_NATIVE token is:

 <module name="IllegalToken">
     <property name="tokens" value="LITERAL_NATIVE"/>
 </module>
