java.lang.Objectorg.restlet.util.ByteUtils
public final class ByteUtils
Byte manipulation utilities.
Method Summary | |
---|---|
static long |
exhaust(InputStream input)
Exhauts the content of the representation by reading it and silently discarding anything read. |
static ReadableByteChannel |
getChannel(InputStream inputStream)
Returns a readable byte channel based on a given inputstream. |
static WritableByteChannel |
getChannel(OutputStream outputStream)
Returns a writable byte channel based on a given output stream. |
static ReadableByteChannel |
getChannel(Representation representation)
Returns a readable byte channel based on the given representation's content and its write(WritableByteChannel) method. |
static Reader |
getReader(InputStream stream,
CharacterSet characterSet)
Returns a reader from an input stream and a character set. |
static Reader |
getReader(WriterRepresentation representation)
Returns a reader from a writer representation.Internally, it uses a writer thread and a pipe stream. |
static InputStream |
getStream(ReadableByteChannel readableChannel)
Returns an input stream based on a given readable byte channel. |
static InputStream |
getStream(Reader reader,
CharacterSet characterSet)
Returns an input stream based on a given character reader. |
static InputStream |
getStream(Representation representation)
Returns an input stream based on the given representation's content and its write(OutputStream) method. |
static OutputStream |
getStream(WritableByteChannel writableChannel)
Returns an output stream based on a given writable byte channel. |
static OutputStream |
getStream(Writer writer)
Returns an output stream based on a given writer. |
static String |
toString(InputStream inputStream)
Converts an input stream to a string. As this method uses the InputstreamReader class, the default character set is used for decoding the input stream. |
static String |
toString(InputStream inputStream,
CharacterSet characterSet)
Converts an input stream to a string using the specified character set for decoding the input stream. |
static String |
toString(Reader reader)
Converts a reader to a string. |
static void |
write(FileChannel fileChannel,
WritableByteChannel writableChannel)
Writes the representation to a byte channel. |
static void |
write(InputStream inputStream,
OutputStream outputStream)
Writes an input stream to an output stream. |
static void |
write(InputStream inputStream,
RandomAccessFile randomAccessFile)
Writes an input stream to a random access file. |
static void |
write(ReadableByteChannel readableChannel,
WritableByteChannel writableChannel)
Writes a readable channel to a writable channel. |
static void |
write(Reader reader,
Writer writer)
Writes characters from a reader to a writer. |
