Constructor Detail

StreamNormalizingReader

public StreamNormalizingReader(InputStream is)
                        throws IOException
Creates a new NormalizingReader. The encoding is assumed to be ISO-8859-1.

Parameters:
is - The input stream to decode.

StreamNormalizingReader

public StreamNormalizingReader(InputStream is,
                               String enc)
                        throws IOException
Creates a new NormalizingReader.

Parameters:
is - The input stream to decode.
enc - The standard encoding name. A null encoding means ISO-8859-1.

StreamNormalizingReader

public StreamNormalizingReader(Reader r)
                        throws IOException
Creates a new NormalizingReader.

Parameters:
r - The reader to wrap.

StreamNormalizingReader

protected StreamNormalizingReader()
This constructor is intended for use by subclasses.

Method Detail

read

public int read()
         throws IOException
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.

Throws:
IOException

getLine

public int getLine()
Returns the current line in the stream.

Specified by:
getLine in class NormalizingReader

getColumn

public int getColumn()
Returns the current column in the stream.

Specified by:
getColumn in class NormalizingReader

close

public void close()
           throws IOException
Close the stream.

Throws:
IOException

createCharDecoder

protected CharDecoder createCharDecoder(InputStream is,
                                        String enc)
                                 throws IOException
Creates the CharDecoder mapped with the given encoding name.

Throws:
IOException
