EscapeContLineReader

• java.lang.Object
  • ContLineReader

Fields Summary
public static final char	ESCAPE The default escape character.
protected char	escape The actual escape character.
protected boolean	hitEOF EOF flag, needed since we use super.readLine() several places
protected static String	sampleTxt

Constructors Summary
public EscapeContLineReader(Reader in) Construct a EscapeContLineReader with the default input-buffer size. super(in);
public EscapeContLineReader(Reader in, int sz) Construct a EscapeContLineReader using the given input-buffer size. super(in, sz);
public EscapeContLineReader(Reader in, char esc) Construct an EscapeContLineReader given a Reader and a non-default escape character. super(in); escape = esc;

Methods Summary
public int	getLineNumber() Line number of first line in current (possibly continued) line return firstLineNumber;
public static void	main(java.lang.String[] argv) EscapeContLineReader is = new EscapeContLineReader( new StringReader(sampleTxt)); String aLine; while ((aLine = is.readLine()) != null) { System.out.println(is.getLineNumber() + ": " + aLine); } is.close();
public java.lang.String	readLine() Read one (possibly continued) line, stripping out the \ that marks the end of each line but the last in a sequence. // Read the first line, save its contents in the StringBuffer // and its line number in firstLineNumber. String s = readPhysicalLine(); if (s == null) hitEOF = true; if (hitEOF) return null; StringBuffer sb = new StringBuffer(s); firstLineNumber = super.getLineNumber(); // Now read as many continued lines as there are. while (sb.length() > 0 && sb.charAt(sb.length() - 1) == escape) { sb.setLength(sb.length() - 1); // Kill the escape // sb.deleteCharAt(sb.length() - 1);// Java 2 - kill it String nextPart = readPhysicalLine(); if (nextPart == null) { hitEOF = true; throw new IOException( "EOF within continued line at line " + firstLineNumber); } sb.append(' ").append(nextPart); // and add line. } return sb.toString();
