Source Link

Document

Creates a new char buffer by wrapping the given char sequence.

Usage

From source file:Main.java

public static void writeData(SeekableByteChannel seekableChannel, Charset cs) throws IOException {
    String separator = System.getProperty("line.separator");
    StringBuilder sb = new StringBuilder();
    sb.append("test");
    sb.append(separator);/*from  w w w  .  j ava  2s  . c om*/
    sb.append("test2");
    sb.append(separator);

    CharBuffer charBuffer = CharBuffer.wrap(sb);
    ByteBuffer byteBuffer = cs.encode(charBuffer);
    seekableChannel.write(byteBuffer);
}
