Method Detail

close

public static void close(Socket socket,
         Closeable... closeables)

close

public static void close(PreparedStatement ps,
         ResultSet... rs)

Close a PreparedStatement and a series of result sets. Use this in a finally clause. While closing the PreparedStatement supposedly closes it's resultsets, i was told that some buggy implementations don't. Exists because PreparedStatement and ResultŜet are only closeable on jdk 1.7

Parameters:

ps - ps

rs - rs

close

public static void close(Closeable... closeables)

Close closeables. Use this in a finally clause.

Parameters:

closeables - closeables to close.

listBasenames

public static String[] listBasenames(File directory,
                     String suffix)

List the basenames of all files in directory that end in suffix, without that suffix. For example, if suffix is ".wav", return the names of all .wav files in the directory, but without the .wav extension. The file names are sorted in alphabetical order, according to java's string search.

Parameters:

directory - directory

suffix - suffix

Returns:

filenames

getFileAsString

Deprecated. use FileUtils.readFileToString(File, String) instead

Read a file into a string, using the given encoding, and return that string.

Parameters:

file - file

encoding - encoding

Returns:

stream as string(fis, encoding)

Throws:

IOException - IOException
