public class ParenPadCheck extends AbstractOptionCheck<PadOption>
Checks the padding of parentheses; that is whether a space is required
after a left parenthesis and before a right parenthesis, or such spaces are
forbidden, with the exception that it does
not check for padding of the right parenthesis at an empty for iterator.
Use Check EmptyForIteratorPad
to validate
empty for iterators.
The policy to verify is specified using the PadOption
class and
defaults to PadOption.NOSPACE
.
By default the check will check parentheses that occur with the following
tokens:
CTOR_CALL
,
LPAREN
,
METHOD_CALL
,
RPAREN
,
SUPER_CTOR_CALL
,
An example of how to configure the check is:
<module name="ParenPad"/>
An example of how to configure the check to require spaces for the parentheses of constructor, method, and super constructor invocations is:
<module name="ParenPad"> <property name="tokens" value="CTOR_CALL, METHOD_CALL, SUPER_CTOR_CALL"/> <property name="option" value="space"/> </module>
