public class IOUtils
extends java.lang.Object

General IO stream manipulation utilities. Some functions are based on org.apache.commons.io

This class provides static utility methods for input/output operations.

• closeQuietly - these methods close a stream ignoring nulls and exceptions

closeQuietly

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

Unconditionally close an InputStream.

Equivalent to InputStream.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

closeQuietly

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

Unconditionally close a Writer.

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

Parameters:

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