All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

public class NaftahOutputTransformer
extends OutputStream

An OutputStream wrapper that transforms text for proper visual display when printed to an output stream (e.g., console or file).

If text is detected and reshaping is enabled, the text will be reshaped before being written. Otherwise, the original content is passed through.

Note: The methods shouldReshape(), containsArabic(String), and shape(String) are assumed to be implemented elsewhere.

Constructor Details

NaftahOutputTransformer

public NaftahOutputTransformer(OutputStream original)

Constructs a new NaftahOutputTransformer wrapping the specified output stream.

Parameters:

original - the original output stream

Method Details

getPrintStream

public static PrintStream getPrintStream(OutputStream original)

Returns a PrintStream that wraps the provided output stream and applies text transformation.

Parameters:

original - the original output stream to wrap

Returns:

a PrintStream using NaftahOutputTransformer

write

public void write(int b)
           throws IOException

Writes a single byte to the original output stream. This method serves as a fallback when writing raw byte data.

Specified by:

write in class OutputStream

Parameters:

b - the byte to write

Throws:

IOException - if an I/O error occurs

write

public void write(byte[] b,
 int off,
 int len)
           throws IOException

Writes a portion of a byte array to the output stream. If the content contains text and reshaping is enabled, it reshapes the text before writing. Otherwise, writes the original byte sequence.

Overrides:

write in class OutputStream

Parameters:

b - the byte array containing the data

off - the start offset in the array

len - the number of bytes to write

Throws:

IOException - if an I/O error occurs
