Method Detail

closeQuietly

public static void closeQuietly(java.io.InputStream input)

Unconditionally close an InputStream.

Equivalent to IOHelper.SafeURLInputStream.close(), except any exceptions will be ignored. This is typically used in finally blocks.

Parameters:

input - the InputStream to close, may be null or already closed

closeQuietly

public static void closeQuietly(java.io.OutputStream output)

Unconditionally close an OutputStream.

Equivalent to OutputStream.close(), except any exceptions will be ignored. This is typically used in finally blocks.

Parameters:

output - the OutputStream to close, may be null or already closed

copy

public static int copy(java.io.InputStream input,
                       java.io.OutputStream output)
                throws java.io.IOException

Copy bytes from an InputStream to an OutputStream.

This method buffers the input internally, so there is no need to use a BufferedInputStream.

Parameters:

input - the InputStream to read from

output - the OutputStream to write to

Returns:

the number of bytes copied

Throws:

java.lang.NullPointerException - if the input or output is null

java.io.IOException - if an I/O error occurs

Since:

Commons IO 1.1

getInputStream

public static java.io.InputStream getInputStream(java.net.URL url)
                                          throws java.io.IOException

Throws:

java.io.IOException
