It scans {@link java.beans.Expression} and + * {@link java.beans.Statement} instances and some raw objects via the + * {@link #writeObject} method and feeds it to a state machine. The + * state machine then constructs and object tree which is finally + * written as XML by a {@link Writer} implementation.</p> + * + * <p>How does it work?</p> + * <p>The <code>ScanEngine</code> sits below the {@link java.beans.XMLEncoder} + * class and is called by it exclusively. The <code>XMLEncoder</code> sends + * interpretive data by invoking {@link #writeExpression}, {@link #writeStatement} + * and {@link #writeObject}. The invocations of <code>writeExpression</code> and + * <code>writeStatement</code> are usually nested into each other and provide + * more information then necessary to generate the XML representation. + * Furthermore the meaning of certain <code>Expressions</code> differs + * depending on the enclosing elements or the inner elements have to be + * simply discarded.</p> + * + * <p>To cope with this state dependant nature the <code>ScanEngine</code> + * contains a state machine which is programmed statically (no adjustments are + * needed, all <code>ScanEngine</code> engines use the same setup). The + * <code>ScanEngine</code>'s job is to decode the <code>Expression</code>s, + * <code>Statement</code>s and certain objects (namely <code>String</code>, + * <code>null</code> objects and instances which are repeatedly provided to + * the encoder) into 13 low-level (event) methods, which denote the meaning of the + * argument. For example an <code>Expression</code> can be an array + * instantiation which provokes a call to {@link arrayInstantiation} or + * it can be a class resolution leading to a call to {@link #classResolution}. + * For the state machione the 13 methods are the distinct way to transit + * from one state to another. Whenever the <code>ScanEngine</code> calls + * one of the event methods the current's state successor for that event + * is fetched from the state machine configuration, the successpr becomes + * the current state and then the event method is called in the new current + * state. The last step allows the state instance to do something meaningful + * to the object tree.</p> + * + * <p>The state machine knows the concept of returning to the previous + * state. This is done using a stack of states which is popped every + * time a call to <code>writeStatement</code>, <code>writeExpression</code> + * in the <code>XMLEncoder</code> ends by calling the {@link #end} method. + * Note that due to the inheritance relationship of <code>Encoder</code> + * and <code>XMLEncoder</code> it is impossible for the + * <code>ScanEngine</code> itself to decide when an expression or statement + * ended. This can only be done in case of {@link #writeObject} calls because + * they are not nested.</p> + * + * <p>When the XML persistence mechanism reaches an object twice (and more) + * it should generate an XML element using the "idref" attribute and add + * an "id" attribute to its first instantiation. This complicates things a bit + * because the first instantiation will always be part of the object tree + * as some {@link gnu.java.beans.encoder.elements.Element} subclass instance when the + * second and further objects accesses are written. Therefore the {@link ObjectId} + * class was introduced which is shared between all the object tree elements + * and has the notion of an "unused" state meaning that no identification + * is needed. The relationship between an object and its <code>ObjectId</code> + * instance is stored in the <code>ScanEngine</code> and gets cleared whenever + * the {@link #flush} method is called. This method also writes the currently + * built object tree and generates the XML representation.</p> + * + * @author Robert Schuster (robertschuster@fsfe.org) + */ +public class ScanEngine +{ + + /** Change this to true to let the ScanEngine print state transition + * information. + */ + boolean DEBUG = false; + + /** + * Stores the scanner engine states as values and their names as keys. + */ + HashMap states = new HashMap(); + + /** + * Stores former scanner state and makes it possible to come back to them. + */ + Stack parents = new Stack(); + + /** + * The currently active scanner state. + */ + ScannerState current; + + /** + * The root of an object tree that is later written to XML. + */ + Root root; + + /** + * The Writer used to generate the XML output. + */ + Writer writer; + + /** Stores the relationship between objects and their {@link ObjectId} instance. + */ + IdentityHashMap objects = new IdentityHashMap(); + + public ScanEngine(OutputStream os) + { + // TODO: Provide another Writer implementation (e.g. one that does not use + // the XML APIs at all). + writer = new StAXWriter(os); + root = new Root(); + + final ScannerState start = current = new GenericScannerState(root); + ScannerState conf; + + // Use the ReportingScannerState to debug serialization issues. + register(ScannerState.DEFAULT_STATE_NAME, new IgnoringScannerState()); + + register("start", start); + + // Special dead-end state where all transitions are ignored. + register("ignoreAll", new IgnoringScannerState()) + .setDefaultSuccessor("ignoreAll"); + + // Object reference, string reference, null object + start.putSuccessor(ScannerState.TRANSITION_OBJECT_REFERENCE, "simple"); + start.putSuccessor(ScannerState.TRANSITION_STRING_REFERENCE, "simple"); + start.putSuccessor(ScannerState.TRANSITION_NULL_OBJECT, "simple"); + register("simple", new GenericScannerState(root)) + .setDefaultSuccessor("ignoreAll"); + + // Class resolution. + start.putSuccessor(ScannerState.TRANSITION_CLASS_RESOLUTION, "classRes0"); + register("classRes0", + new GenericScannerState(root)).setDefaultSuccessor("ignoreAll"); + + // Object instantiation. + start.putSuccessor(ScannerState.TRANSITION_OBJECT_INSTANTIATION, + "newObj0"); + conf = register("newObj0", new GenericScannerState(root)); + conf.setDefaultSuccessor("ignoreAll"); + + // Simply use the start state to encode method invocations inside of + // objects. + conf.putSuccessor(ScannerState.TRANSITION_METHOD_INVOCATION, "start"); + + // Primitive instantiations. + start.putSuccessor(ScannerState.TRANSITION_PRIMITIVE_INSTANTIATION, + "newPrimitive0"); + register("newPrimitive0", + new GenericScannerState(root)).setDefaultSuccessor("ignoreAll"); + + // Object arrays use the ARRAY_GET transition to create setting the + // array values. + start.putSuccessor(ScannerState.TRANSITION_OBJECT_ARRAY_INSTANTIATION, + "newObjectArray"); + conf = register("newObjectArray", new GenericScannerState(root)); + conf.putSuccessor(ScannerState.TRANSITION_ARRAY_GET, "newOArrayGet"); + conf.putSuccessor(ScannerState.TRANSITION_ARRAY_SET, "ignoreAll"); + conf.putSuccessor(ScannerState.TRANSITION_CLASS_RESOLUTION, "ignoreAll"); + conf.putSuccessor(ScannerState.TRANSITION_PRIMITIVE_INSTANTIATION, + "ignoreAll"); + + // Get here when a value is set in the array. + register("newOArrayGet", + conf = new GenericScannerState(root)); + + conf.putSuccessor(ScannerState.TRANSITION_PRIMITIVE_INSTANTIATION, + "newOArrayGet_ignoreFirstInteger"); + + // "newArrayGet_ignoreFirstInteger" is set up mostly identical like the "start" + // state.
