closeAll

public static <T extends AutoCloseable> void closeAll(Collection<T> closeables)
                                               throws IOException

Closes given collection of closeables.

Type Parameters:

T - the type of closeable

Parameters:

closeables - the closeables to close

Throws:

IOException - if an exception was thrown by one of the close methods.

closeAll(AutoCloseable[])

closeAllUnchecked

public static <T extends AutoCloseable> void closeAllUnchecked(Collection<T> closeables)
                                                        throws UncheckedIOException

Close all the provided closeables, chaining exceptions, if any, into a single UncheckedIOException.

Type Parameters:

T - the type of closeable.

Parameters:

closeables - to call close on.

Throws:

UncheckedIOException - if any exception is thrown from any of the closeables.

closeAllUnchecked

@SafeVarargs
public static <T extends AutoCloseable> void closeAllUnchecked(T... closeables)
                                                                     throws UncheckedIOException

Close all the provided closeables, chaining exceptions, if any, into a single UncheckedIOException.

Type Parameters:

T - the type of closeable.

Parameters:

closeables - to call close on.

Throws:

UncheckedIOException - if any exception is thrown from any of the closeables.

closeAllSilently

public static <T extends AutoCloseable> void closeAllSilently(Collection<T> closeables)

Closes given collection of closeables ignoring all exceptions.

Type Parameters:

T - the type of closeable

Parameters:

closeables - the closeables to close

See Also:

closeAll(AutoCloseable[])

closeAll

@SafeVarargs
public static <T extends AutoCloseable> void closeAll(T... closeables)
                                                            throws IOException

Closes given array of closeables. If any AutoCloseable.close() call throws IOException than it will be rethrown to the caller after calling AutoCloseable.close() on other given resources. If more than one AutoCloseable.close() throw than resulting exception will have suppressed exceptions. See Throwable.addSuppressed(Throwable)

Type Parameters:

T - the type of closeable

Parameters:

closeables - the closeables to close

Throws:

IOException - if an exception was thrown by one of the close methods.

closeAllSilently

@SafeVarargs
public static <T extends AutoCloseable> void closeAllSilently(T... closeables)

Closes given array of closeables ignoring all exceptions.

Type Parameters:

T - the type of closeable

Parameters:

closeables - the closeables to close

close

public static <T extends AutoCloseable,E extends Throwable> void close(BiFunction<String,Throwable,E> constructor,
                                                                       Collection<T> closeables)
                                                                throws E extends Throwable

Close all ofthe given closeables, and if something goes wrong, use the given constructor to create a Throwable instance with the specific cause attached. The remaining closeables will still be closed, in that case, and if they in turn throw any exceptions then these will be attached as suppressed exceptions.

Type Parameters:

T - the type of things to close.

E - the type of the parent exception.

Parameters:

constructor - The function used to construct the parent throwable that will have the first thrown exception attached as a cause, and any remaining exceptions attached as suppressed exceptions. If this function returns null, then the exception is ignored.

closeables - an iterator of all the things to close, in order.

Throws:

E - when any AutoCloseable.close() throws exception

E extends Throwable

Close all ofthe given closeables, and if something goes wrong, use the given constructor to create a Throwable instance with the specific cause attached. The remaining closeables will still be closed, in that case, and if they in turn throw any exceptions then these will be attached as suppressed exceptions.

Type Parameters:

T - the type of things to close.

E - the type of the parent exception.

Parameters:

constructor - The function used to construct the parent throwable that will have the first thrown exception attached as a cause, and any remaining exceptions attached as suppressed exceptions. If this function returns null, then the exception is ignored.
