public class WhitespaceAroundCheck
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
,
BXOR_ASSIGN
,
COLON
,
DIV
,
DIV_ASSIGN
,
EQUAL
,
GE
,
GT
,
LAND
,
LCURLY
,
LE
,
LITERAL_CATCH
,
LITERAL_DO
,
LITERAL_ELSE
,
LITERAL_FINALLY
,
LITERAL_FOR
,
LITERAL_IF
,
LITERAL_RETURN
,
LITERAL_SYNCHRONIZED
,
LITERAL_TRY
,
LITERAL_WHILE
,
LOR
,
LT
,
MINUS
,
MINUS_ASSIGN
,
MOD
,
MOD_ASSIGN
,
NOT_EQUAL
,
PLUS
,
PLUS_ASSIGN
,
QUESTION
,
RCURLY
,
SL
,
SLIST
,
SL_ASSIGN
,
SR
,
SR_ASSIGN
,
STAR
,
STAR_ASSIGN
.
LITERAL_ASSERT
.
TYPE_EXTENSION_AND
.
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" />
Also, this check can be configured to ignore the colon in an enhanced for loop. The colon in an enhanced for loop is ignored by default
To configure the check to ignore the colon
<property name="ignoreEnhancedForColon" value="true" />
