Method Detail

closeQuietly

public static void closeQuietly(Reader aReader)

Closes a reader, catching and logging any exceptions.

Parameters:

aReader - A supplied reader to close

closeQuietly

public static void closeQuietly(Writer aWriter)

Closes a writer, catching and logging any exceptions.

Parameters:

aWriter - A supplied writer to close

closeQuietly

public static void closeQuietly(InputStream aInputStream)

Closes an input stream, catching and logging any exceptions.

Parameters:

aInputStream - A supplied input stream to close

closeQuietly

public static void closeQuietly(ImageInputStream aImageInputStream)

Closes an image input stream, catching and logging any exceptions

Parameters:

aImageInputStream - A supplied image input stream to close

closeQuietly

public static void closeQuietly(ImageOutputStream aImageOutputStream)

Closes an image output stream, catching and logging any exceptions.

Parameters:

aImageOutputStream - A supplied image output stream to close

closeQuietly

public static void closeQuietly(OutputStream aOutputStream)

Closes an output stream, catching and logging any exceptions.

Parameters:

aOutputStream - A supplied output stream to close

closeQuietly

public static void closeQuietly(JarFile aJarFile)

Closes a JarFile, catching and logging any exceptions.

Parameters:

aJarFile - A supplied JarFile to close

copyStream

public static void copyStream(InputStream aInStream,
                              OutputStream aOutStream)
                       throws IOException

Writes from an input stream to an output stream; you're responsible for closing the InputStream and OutputStream.

Parameters:

aInStream - The stream from which to read

aOutStream - The stream from which to write

Throws:

IOException - If there is trouble reading or writing

copyStream

public static void copyStream(File aFile,
                              OutputStream aOutStream)
                       throws IOException

Writes a file to an output stream. You're responsible for closing the OutputStream; the input stream is closed for you since just a File was passed in.

Parameters:

aFile - A file from which to read

aOutStream - An output stream to which to write

Throws:

IOException - If there is a problem reading or writing

readBytes

public static byte[] readBytes(InputStream aInputStream)
                        throws IOException

Reads an InputStream into a byte array.

Parameters:

aInputStream - The input stream from which to read

Returns:

The array of bytes

Throws:

IOException - If there is trouble reading from the input stream
