Method Detail

closeQuietly

public static IOException closeQuietly(@Nullable
                       Closeable closeable)

Close a Closeable, returning an IOException if it occurs while closing instead of throwing it. This is nearly a clone of the Guava Closeables.closeQuietly method which has long since been removed from Guava. Use of this method should be avoided -- quietly swallowing IOExceptions (particularly on Closeables that are being written to) is a code smell. Use of the equivalent method in Guava was done for this reason.

Parameters:

closeable - the Closeable to be closed, can be null

Returns:

the IOException if one was thrown, otherwise null

closeAll

public static void closeAll(Iterable<? extends Closeable> iterable)
                     throws IOException

Allows you to close as many of the Closeables as possible. If any of the close's fail with an IOException, those exception(s) will be thrown after attempting to close all of the inputs.

Throws:

IOException

closeAllQuietly

public static IOException closeAllQuietly(Iterable<? extends Closeable> iterable)
