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. |
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.
