Methods Summary
public final void	endDocument() Process notification of the end of a document and write generated bytecode into output stream. exception SAXException if parsing or writing error is to be reported. try { os.write( cw.toByteArray()); } catch( IOException ex) { throw new SAXException( ex.toString(), ex); }
public final void	endElement(java.lang.String ns, java.lang.String localName, java.lang.String qName) Process notification of the end of an XML element being reached. param ns - The Namespace URI, or the empty string if the element has no Namespace URI or if Namespace processing is not being performed. param localName - The local name (without prefix), or the empty string if Namespace processing is not being performed. param qName - The qualified XML 1.0 name (with prefix), or the empty string if qualified names are not available. exception SAXException if a parsing error is to be reported // the actual element name is either in localName or qName, depending // on whether the parser is namespace aware String name = localName; if( name == null || name.length() < 1) { name = qName; } // Fire "end" events for all relevant rules in reverse order for( int i = 0; i < RULES.length; i++) { if( RULES[ i].match( match, name)) { RULES[ i].end( name); } } // Recover the previous match expression int slash = match.lastIndexOf( '/"); if( slash >= 0) { match = match.substring( 0, slash); } else { match = ""; }
final java.lang.Object	peek() Return the top object on the stack without removing it. If there are no objects on the stack, return null. return stack.size()==0 ? null : stack.get( stack.size()-1);
final java.lang.Object	peek(int n) Return the n'th object down the stack, where 0 is the top element and [getCount()-1] is the bottom element. If the specified index is out of range, return null. param n Index of the desired element, where 0 is the top of the stack, 1 is the next element down, and so on. return stack.size()<( n+1) ? null : stack.get( n);
final java.lang.Object	pop() Pop the top object off of the stack, and return it. If there are no objects on the stack, return null. return stack.size()==0 ? null : stack.remove( stack.size()-1);
final void	push(java.lang.Object object) Push a new object onto the top of the object stack. param object The new object stack.add( object);
public final void	startElement(java.lang.String ns, java.lang.String localName, java.lang.String qName, org.xml.sax.Attributes list) Process notification of the start of an XML element being reached. param ns - The Namespace URI, or the empty string if the element has no Namespace URI or if Namespace processing is not being performed. param localName - The local name (without prefix), or the empty string if Namespace processing is not being performed. param qName - The qualified name (with prefix), or the empty string if qualified names are not available. param list - The attributes attached to the element. If there are no attributes, it shall be an empty Attributes object. exception SAXException if a parsing error is to be reported // the actual element name is either in localName or qName, depending // on whether the parser is namespace aware String name = localName; if( name==null || name.length()<1) { name = qName; } // Compute the current matching rule StringBuffer sb = new StringBuffer( match); if( match.length() > 0) { sb.append( '/"); } sb.append( name); match = sb.toString(); // Fire "begin" events for all relevant rules for( int i = 0; i < RULES.length; i++) { if( RULES[ i].match( match, name)) { RULES[ i].begin( name, list); } }
public byte[]	toByteArray() Returns the bytecode of the class that was build with underneath class writer. return the bytecode of the class that was build with underneath class writer or null if there are no classwriter created. return cw==null ? null : cw.toByteArray();
