all

public static AutoCloseable all(Collection<? extends AutoCloseable> autoCloseables)

close

public static void close(Throwable t,
                         AutoCloseable... autoCloseables)

Closes all autoCloseables if not null and suppresses exceptions by adding them to t.

パラメータ:

t - the throwable to add suppressed exception to

autoCloseables - the closeables to close

close

public static void close(Throwable t,
                         Iterable<? extends AutoCloseable> autoCloseables)

Closes all autoCloseables if not null and suppresses exceptions by adding them to t.

パラメータ:

t - the throwable to add suppressed exception to

autoCloseables - the closeables to close

close

public static void close(AutoCloseable... autoCloseables)
                  throws Exception

Closes all autoCloseables if not null and suppresses subsequent exceptions if more than one.

パラメータ:

autoCloseables - the closeables to close

例外:

Exception

public static void close(Iterable<? extends AutoCloseable> ac)
                  throws Exception

Closes all autoCloseables if not null and suppresses subsequent exceptions if more than one.

パラメータ:

ac - the closeables to close

例外:

@SafeVarargs
public static void close(Iterable<? extends AutoCloseable>... closeables)
                               throws Exception

例外:

Exception

iter

public static Iterable<AutoCloseable> iter(AutoCloseable... ac)

rollbackable

public static AutoCloseables.RollbackCloseable rollbackable(AutoCloseable... closeables)

closeNoChecked

public static void closeNoChecked(AutoCloseable autoCloseable)

close() an AutoCloseable without throwing a (checked) Exception. This wraps the close() call with a try-catch that will rethrow an Exception wrapped with a RuntimeException, providing a way to call close() without having to do the try-catch everywhere or propagate the Exception.

パラメータ:

autoCloseable - the AutoCloseable to close; may be null

例外:

RuntimeException - if an Exception occurs; the Exception is wrapped by the RuntimeException

noop

public static AutoCloseable noop()

戻り値:
