Class EmptyBlockCheck

Implemented Interfaces:
Configurable, Contextualizable
public class EmptyBlockCheck
extends AbstractOptionCheck
Checks for empty blocks. The policy to verify is specified using the BlockOption class and defaults to BlockOption.STMT.

By default the check will check the following blocks: LITERAL_WHILE, LITERAL_TRY, LITERAL_CATCH, LITERAL_FINALLY, LITERAL_DO, LITERAL_IF, LITERAL_ELSE, LITERAL_FOR, STATIC_INIT.

An example of how to configure the check is:

    <property name="tokens" value="LITERAL_CATCH"/>
    <property name="option" value="text"/>
 </module>
