void saxparse.TestMain.main (  String[]  args  )  [static]

{ TestMain t = new TestMain(); t.test( args ); }

boolean saxparse.TestMain.parseValidateFlag (  String  validateFlag  )  [private]

Parse the validate flag. The flag will be either validate=false validate=true If the flag has some other value the method will print a message and return true (since the value for the validate flag is true by default). { boolean validate = true; boolean flagOK = false; validateFlag = validateFlag.trim(); if (validateFlag.startsWith("validate")) { int eqIx = validateFlag.indexOf("="); if (eqIx > 0) { String boolStr = validateFlag.substring( eqIx + 1 ); boolStr = boolStr.trim(); if (boolStr.equals("true") || boolStr.equals("false")) { flagOK = true; if (boolStr.equals("false")) { validate = false; } } } } if (! flagOK) { String name = getClass().getName(); System.out.println("validate flag usage: \"validate=false\" or \"validate=true\""); } return validate; } // parseValidateFlag

void saxparse.TestMain.printList (  ArrayList  msgList  )  [private]

Print the trade engine messages to standard output. { int len = msgList.size(); for (int i = 0; i < len; i++) { Object obj = msgList.get( i ); if (obj instanceof AimOrder) { AimOrder t = (AimOrder)obj; System.out.println("Aim Order:"); System.out.println( t ); } else if (obj instanceof Control) { Control t = (Control)obj; System.out.println("Control:"); System.out.println( t ); } else { System.out.println("Unexpected object in msgList:" + obj.getClass().getName()); } } } // printList

void saxparse.TestMain.printSAXError (  SAXParseException  e, String  xmlFileName )  [private]

{ int lineNum = e.getLineNumber(); int columnNumber = e.getColumnNumber(); String exceptionMsg = e.getMessage(); String msg = xmlFileName + "(" + lineNum + ", " + columnNumber + "): " + exceptionMsg; System.out.println(msg); } // printSAXError

void saxparse.TestMain.test (  String[]  args  )  [private]

Use the SAX parser to parse trade engine messages read from a file. { if (args.length >= 1 && args.length <= 2) { String xmlFileName = null; boolean validate = true; for (int i = 0; i < args.length; i++) { switch (i) { case 0: xmlFileName = args[0]; break; case 1: String validateFlag = args[1]; validate = parseValidateFlag( validateFlag ); break; } // switch; } // for InputStream in = null; try { in = new FileInputStream( xmlFileName ); ArrayList msgList = new ArrayList(); MessageProcessor msgHandler = new MessageProcessor( msgList ); ParseMessage msgParser = new ParseMessage(); msgParser.parse( in, msgHandler, validate ); printList( msgList ); } catch (FileNotFoundException e) { System.out.println("Error opening file " + xmlFileName + " = " + e); } catch (SAXException e1) { printSAXError( (SAXParseException)e1, xmlFileName ); } } else { usage(); } } // test

void saxparse.TestMain.usage (   )  [private]

{ String name = getClass().getName(); System.out.println("usage: " + name + "<XML fileName> [validate=true/false]"); System.out.println(" Where the <XML fileName> is the file name of an XML document"); System.out.println(" The default for validate is \"true\""); }
