Constructor Detail

StreamNormalizingReader

public StreamNormalizingReader(java.io.InputStream is)
                        throws java.io.IOException

Creates a new NormalizingReader. The encoding is assumed to be ISO-8859-1.

Parameters:

is - The input stream to decode.

StreamNormalizingReader

public StreamNormalizingReader(java.io.InputStream is,
                               java.lang.String enc)
                        throws java.io.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(java.io.Reader r)
                        throws java.io.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 java.io.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 java.io.Reader

getLine

public int getLine()

Returns the current line in the stream.

Overrides:

getLine in class NormalizingReader

getColumn

public int getColumn()

Returns the current column in the stream.

Overrides:

getColumn in class NormalizingReader

close

public void close()
           throws java.io.IOException

Close the stream.

Overrides:

close in class java.io.Reader

createCharDecoder

protected CharDecoder createCharDecoder(java.io.InputStream is,
                                        java.lang.String enc)
                                 throws java.io.IOException

Creates the CharDecoder mapped with the given encoding name.
