== Exceptions
|
|
|
|
Instances of the following classes are ignored by this rule because ``++close++`` has no effect:
|
|
|
|
* ``++java.io.ByteArrayOutputStream++``
|
|
* ``++java.io.ByteArrayInputStream++``
|
|
* ``++java.io.CharArrayReader++``
|
|
* ``++java.io.CharArrayWriter++``
|
|
* ``++java.io.StringReader++``
|
|
* ``++java.io.StringWriter++``
|
|
|
|
Java 7 introduced the try-with-resources statement, which implicitly closes ``++Closeables++``. All resources opened in a try-with-resources statement are ignored by this rule.
