UTF8Reader
public UTF8Reader(InputStream inputStream, int size)
Deprecated.Constructs a UTF-8 reader from the specified input stream, buffer size and MessageFormatter.- Parameters:
inputStream
- The input stream.size
- The initial buffer size.
-
-
Method Detail
-
read
public int read() throws IOException
Deprecated.Read a single character. This method will block until a character is available, an I/O error occurs, or the end of the stream is reached.Subclasses that intend to support efficient single-character input should override this method.
- Overrides:
read
in classReader
- Returns:
- The character read, as an integer in the range 0 to 16383
(
0x00-0xffff
), or -1 if the end of the stream has been reached - Throws:
IOException
- If an I/O error occurs
-
read
public int read(char[] ch, int offset, int length) throws IOException
Deprecated.Read characters into a portion of an array. This method will block until some input is available, an I/O error occurs, or the end of the stream is reached.- Specified by:
read
in classReader
- Parameters:
ch
- Destination bufferoffset
- Offset at which to start storing characterslength
- Maximum number of characters to read- Returns:
- The number of characters read, or -1 if the end of the stream has been reached
- Throws:
IOException
- If an I/O error occurs
-
skip
public long skip(long n) throws IOException
Deprecated.Skip characters. This method will block until some characters are available, an I/O error occurs, or the end of the stream is reached.- Overrides:
skip
in classReader
- Parameters:
n
- The number of characters to skip- Returns:
- The number of characters actually skipped
- Throws:
IOException
- If an I/O error occurs
-
ready
public boolean ready() throws IOException
Deprecated.Tell whether this stream is ready to be read.- Overrides:
ready
in classReader
- Returns:
- True if the next read() is guaranteed not to block for input, false otherwise. Note that returning false does not guarantee that the next read will block.
- Throws:
IOException
- If an I/O error occurs
-
markSupported
public boolean markSupported()
Deprecated.Tell whether this stream supports the mark() operation.- Overrides:
markSupported
in classReader
-
mark
public void mark(int readAheadLimit) throws IOException
Deprecated.Mark the present position in the stream. Subsequent calls to reset() will attempt to reposition the stream to this point. Not all character-input streams support the mark() operation.- Overrides:
mark
in classReader
- Parameters:
readAheadLimit
- Limit on the number of characters that may be read while still preserving the mark. After reading this many characters, attempting to reset the stream may fail.- Throws:
IOException
- If the stream does not support mark(), or if some other I/O error occurs
-
reset
public void reset() throws IOException
Deprecated.Reset the stream. If the stream has been marked, then attempt to reposition it at the mark. If the stream has not been marked, then attempt to reset it in some way appropriate to the particular stream, for example by repositioning it to its starting point. Not all character-input streams support the reset() operation, and some support reset() without supporting mark().- Overrides:
reset
in classReader
- Throws:
IOException
- If the stream has not been marked, or if the mark has been invalidated, or if the stream does not support reset(), or if some other I/O error occurs
-
close
public void close() throws IOException
Deprecated.Close the stream. Once a stream has been closed, further read(), ready(), mark(), or reset() invocations will throw an IOException. Closing a previously-closed stream, however, has no effect.- Specified by:
close
in interfaceAutoCloseable
- Specified by:
close
in interfaceCloseable
- Specified by:
close
in classReader
- Throws:
IOException
- If an I/O error occurs
