public class ParenPadCheck extends AbstractParenPadCheck
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. No check occurs at the right parenthesis after an empty for
iterator, at the left parenthesis before an empty for initialization, or at
the right parenthesis of a try-with-resources resource specification where
the last resource variable has a trailing semi-colon.
Use Check EmptyForIteratorPad to validate
empty for iterators and EmptyForInitializerPad
to validate empty for initializers. Typecasts are also not checked, as there is
TypecastParenPad to validate them.
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:
ANNOTATION,
ANNOTATION_FIELD_DEF,
CTOR_DEF,
CTOR_CALL,
DOT,
ENUM_CONSTANT_DEF,
EXPR,
LITERAL_CATCH,
LITERAL_DO,
LITERAL_FOR,
LITERAL_IF,
LITERAL_NEW,
LITERAL_SWITCH,
LITERAL_SYNCHRONIZED,
LITERAL_WHILE,
METHOD_CALL,
METHOD_DEF,
RESOURCE_SPECIFICATION,
SUPER_CTOR_CALL,
QUESTION,
LAMBDA,
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>
