Constructor Details

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.

Throws:

IOException

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.

Throws:

IOException

StreamNormalizingReader

public StreamNormalizingReader(Reader r)
                        throws IOException

Creates a new NormalizingReader.

Parameters:

r - The reader to wrap.

Throws:

IOException

StreamNormalizingReader

protected StreamNormalizingReader()

This constructor is intended for use by subclasses.

Method Details

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.

Overrides:

read in class Reader

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.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Specified by:

close in class Reader

Throws:

IOException

createCharDecoder

protected CharDecoder createCharDecoder(InputStream is,
 String enc)
                                 throws IOException

Creates the CharDecoder mapped with the given encoding name.

Throws:

IOException
