All Implemented Interfaces:

Configurable, Contextualizable

public class NoWhitespaceAfterCheck
extends Check

Checks that there is no whitespace after a token. More specifically, it checks that it is not followed by whitespace, or (if linebreaks are allowed) all characters on the line after are whitespace. To forbid linebreaks afer a token, set property allowLineBreaks to false.

By default the check will check the following operators: ARRAY_INIT, BNOT, DEC, DOT, INC, LNOT, UNARY_MINUS, ARRAY_DECLARATOR, UNARY_PLUS. It also supports the operator TYPECAST.

An example of how to configure the check is:

 <module name="NoWhitespaceAfter"/>
 

An example of how to configure the check to forbid linebreaks after a DOT token is:

 <module name="NoWhitespaceAfter">
     <property name="tokens" value="DOT"/>
     <property name="allowLineBreaks" value="false"/>
 </module>
