ExtraDotOutputStream

• java.lang.Object
  • java.io.OutputStream
    • java.io.FilterOutputStream

Fields Summary
protected int	countLast0A0D Counter for number of last (0A or 0D).

Constructors Summary
public ExtraDotOutputStream(OutputStream out) Constructor that wraps an OutputStream. param out the OutputStream to be wrapped super(out); countLast0A0D = 2; // we already assume a CRLF at beginning (otherwise TOP would not work correctly !)

Methods Summary
public void	checkCRLFTerminator() Ensure that the stream is CRLF terminated. throws IOException if an error occurs writing the byte if (countLast0A0D != 2) { write('\n"); }
public void	write(int b) Writes a byte to the stream, adding dots where appropriate. Also fixes any naked CR or LF to the RFC 2821 mandated CFLF pairing. param b the byte to write throws IOException if an error occurs writing the byte switch (b) { case '.": if (countLast0A0D == 2) { // add extra dot (the first of the pair) out.write('."); } countLast0A0D = 0; break; case '\r": if (countLast0A0D == 1) out.write('\n"); // two CR in a row, so insert an LF first countLast0A0D = 1; break; case '\n": /* RFC 2821 #2.3.7 mandates that line termination is * CRLF, and that CR and LF must not be transmitted * except in that pairing. If we get a naked LF, * convert to CRLF. */ if (countLast0A0D != 1) out.write('\r"); countLast0A0D = 2; break; default: // we're no longer at the start of a line countLast0A0D = 0; break; } out.write(b);
