public class NoWhitespaceBeforeCheck extends Check
Checks that there is no whitespace before a token. More specifically, it checks that it is not preceded with whitespace, or (if linebreaks are allowed) all characters on the line before are whitespace. To allow linebreaks before a token, set property allowLineBreaks to true.
By default the check will check the following operators:
SEMI
,
POST_DEC
,
POST_INC
.
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 linebreaks before
a DOT
token is:
<module name="NoWhitespaceBefore"> <property name="tokens" value="DOT"/> <property name="allowLineBreaks" value="true"/> </module>
