Package com.google.common.io

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

See:


          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.
