checkOffsetAndCount

public static void checkOffsetAndCount(long arrayLength,
                                       long offset,
                                       long count)

equal

public static boolean equal(java.lang.Object a,
                            java.lang.Object b)

Returns true if two possibly-null objects are equal.

closeQuietly

public static void closeQuietly(java.io.Closeable closeable)

Closes closeable, ignoring any checked exceptions. Does nothing if closeable is null.

closeQuietly

public static void closeQuietly(java.net.Socket socket)

Closes socket, ignoring any checked exceptions. Does nothing if socket is null.

closeQuietly

public static void closeQuietly(java.net.ServerSocket serverSocket)

Closes serverSocket, ignoring any checked exceptions. Does nothing if serverSocket is null.

closeAll

public static void closeAll(java.io.Closeable a,
                            java.io.Closeable b)
                     throws java.io.IOException

Closes a and b. If either close fails, this completes the other close and rethrows the first encountered exception.

抛出:

java.io.IOException

discard

Attempts to exhaust source, returning true if successful. This is useful when reading a complete source is helpful, such as when doing so completes a cache body or frees a socket connection for reuse.

skipAll

                       throws java.io.IOException

Reads until in is exhausted or the deadline has been reached. This is careful to not extend the deadline if one exists already.

抛出:

java.io.IOException
