Method Details

writeText

public void writeText(WritableByteChannel channel,
 String text)
               throws IOException

Writes text through a channel backed by a byte buffer.

Parameters:

channel - destination channel

text - text to write

Throws:

IOException - when writing fails

readText

public String readText(ReadableByteChannel channel)
                throws IOException

Reads text from a channel using explicit buffer flip and clear phases.

Parameters:

channel - source channel

Returns:

decoded text

Throws:

IOException - when reading fails

Note: this compact example decodes each buffer chunk independently and is intended for ASCII-compatible sample text. Streaming non-ASCII text with multibyte characters split across buffers requires a stateful CharsetDecoder.
