discarding anything read.
|
static long |
getAvailableSize(Representation representation)
Returns the size effectively available.
|
static java.io.Reader |
getReader(java.io.InputStream stream,
CharacterSet characterSet)
Returns a reader from an input stream and a character set.
|
static java.io.Reader |
getReader(WriterRepresentation representation)
Returns a reader from a writer representation.Internally, it uses a
writer thread and a pipe stream.
|
static java.io.InputStream |
getStream(java.io.Reader reader,
CharacterSet characterSet)
Returns an input stream based on a given character reader.
|
static java.io.InputStream |
getStream(Representation representation)
Returns an input stream based on the given representation's content and
its write(OutputStream) method.
|
static java.io.OutputStream |
getStream(java.io.Writer writer)
Returns an output stream based on a given writer.
|
static java.lang.String |
getText(Representation representation)
Converts the representation to a string value.
|
static byte[] |
toByteArray(char[] chars)
Converts a char array into a byte array using the default character set.
|
static byte[] |
toByteArray(char[] chars,
java.lang.String charsetName)
Converts a char array into a byte array using the default character set.
|
static char[] |
toCharArray(byte[] bytes)
Converts a byte array into a character array using the default character
set.
|
static char[] |
toCharArray(byte[] bytes,
java.lang.String charsetName)
Converts a byte array into a character array using the default character
set.
|
static java.lang.String |
toHexString(byte[] byteArray)
Converts a byte array into an hexadecimal string.
|
static java.lang.String |
toString(java.io.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 java.lang.String |
toString(java.io.InputStream inputStream,
CharacterSet characterSet)
Converts an input stream to a string using the specified character set
for decoding the input stream.
|
static java.lang.String |
toString(java.io.Reader reader)
Converts a reader to a string.
