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,
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.
GENERIC_START.
GENERIC_END.
TYPE_EXTENSION_AND.
WILDCARD_TYPE.
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" />
