Description

Interface Summary

ByteArrayDataInput	An extension of DataInput for reading from in-memory byte arrays; its methods offer identical functionality but do not throw IOException.
ByteArrayDataOutput	An extension of DataOutput for writing to in-memory byte arrays; its methods offer identical functionality but do not throw IOException.
ByteProcessor<T>	A callback interface to process bytes from a stream.
InputSupplier<T>	A factory for readable streams of bytes or characters.
LineProcessor<T>	A callback to be used with the streaming readLines methods.
OutputSupplier<T>	A factory for writable streams of bytes or characters.

Class Summary

ByteStreams	Provides utility methods for working with byte arrays and I/O streams.
CharStreams	Provides utility methods for working with character streams.
Closeables	Utility methods for working with Closeable objects.
CountingInputStream	An InputStream that counts the number of bytes read.
CountingOutputStream	An OutputStream that counts the number of bytes written.
FileBackedOutputStream	An OutputStream that starts buffering to a byte array, but switches to file buffering once the data reaches a configurable size.
Files	Provides utility methods for working with files.
Flushables	Utility methods for working with Flushable objects.
LimitInputStream	An InputStream that limits the number of bytes which can be read.
LineReader	A class for reading lines of text.
LittleEndianDataInputStream	An implementation of DataInput that uses little-endian byte ordering for reading short, int, float, double, and long values.
LittleEndianDataOutputStream	An implementation of DataOutput that uses little-endian byte ordering for writing char, short, int, float, double, and long values.
NullOutputStream	Implementation of OutputStream that simply discards written bytes.
PatternFilenameFilter	File name filter that only accepts files matching a regular expression.
Resources	Provides utility methods for working with resources in the classpath.

Package com.google.common.io Description

This package contains utility methods and classes for working with Java I/O, for example input streams, output streams, readers, writers, and files.

Many of the methods are based on the InputSupplier and OutputSupplier interfaces. They are used as factories for I/O objects that might throw IOException when being created. The advantage of using a factory is that the helper methods in this package can take care of closing the resource properly, even if an exception is thrown. The ByteStreams, CharStreams, and Files classes all have static helper methods to create new factories and to work with them.

This package is a part of the open-source Guava libraries.
