public class WhitespaceAroundCheck extends Check
Checks that a token is surrounded by whitespace.
By default the check will check the following operators:
ASSERT
,
ASSIGN
,
BAND
,
BAND_ASSIGN
,
BOR
,
BOR_ASSIGN
,
BSR
,
BSR_ASSIGN
,
BXOR
,

,
MOD
,
MOD_ASSIGN
,

,
PLUS
,
PLUS_ASSIGN
,

SR
,
SR_ASSIGN
,
STAR
,
STAR_ASSIGN

An example of how to configure the check is:
<module name="WhitespaceAround"/>
An example of how to configure the check for whitespace only around assignment operators is:
<module name="WhitespaceAround"> <property name="tokens" value="ASSIGN,DIV_ASSIGN,PLUS_ASSIGN,MINUS_ASSIGN,STAR_ASSIGN,MOD_ASSIGN,SR_ASSIGN,BSR_ASSIGN,SL_ASSIGN,BXOR_ASSIGN,BOR_ASSIGN,BAND_ASSIGN"/> </module>
In addition, this check can be configured to allow empty method and/or constructor bodies. For example, a method with an empty body might look like:
public void doSomething(int val) {}
To configure the check to allow empty method blocks use
<property name="allowEmptyMethods" value="true" />
To configure the check to allow empty constructor blocks use
<property name="allowEmptyConstructors" value="true" />
