Class NoWhitespaceBeforeCheck

  • All Implemented Interfaces:
    Configurable, Contextualizable

    public class NoWhitespaceBeforeCheck
    extends AbstractCheck

    Checks that there is no whitespace before a token. More specifically, it checks that it is not preceded with whitespace, or (if line breaks are allowed) all characters on the line before are whitespace. To allow line breaks before a token, set property allowLineBreaks to true.

    By default the check will check the following operators: COMMA, SEMI, POST_DEC, POST_INC, ELLIPSIS. DOT is also an acceptable token in a configuration of this check.

    An example of how to configure the check is:

     <module name="NoWhitespaceBefore"/>
     

    An example of how to configure the check to allow line breaks before a DOT token is:

     <module name="NoWhitespaceBefore">
         <property name="tokens" value="DOT"/>
         <property name="allowLineBreaks" value="true"/>
     </module>
