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.

Throws:

java.io.IOException

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.

Throws:

java.io.IOException

StreamNormalizingReader

public StreamNormalizingReader(java.io.Reader r)
                        throws java.io.IOException

Creates a new NormalizingReader.

Parameters:

r - The reader to wrap.

Throws:

java.io.IOException

StreamNormalizingReader

protected StreamNormalizingReader()

This constructor is intended for use by subclasses.

Method Detail

read

public int read()
         throws java.io.IOException
