Major merge with Classpath.
Removed many duplicate files.
* HACKING: Updated.x
* classpath: Imported new directory.
* standard.omit: New file.
* Makefile.in, aclocal.m4, configure: Rebuilt.
* sources.am: New file.
* configure.ac: Run Classpath configure script. Moved code around
to support. Disable xlib AWT peers (temporarily).
* Makefile.am (SUBDIRS): Added 'classpath'
(JAVAC): Removed.
(AM_CPPFLAGS): Added more -I options.
(BOOTCLASSPATH): Simplified.
Completely redid how sources are built.
Include sources.am.
* include/Makefile.am (tool_include__HEADERS): Removed jni.h.
* include/jni.h: Removed (in Classpath).
* scripts/classes.pl: Updated to look at built classes.
* scripts/makemake.tcl: New file.
* testsuite/libjava.jni/jni.exp (gcj_jni_compile_c_to_so): Added
-I options.
(gcj_jni_invocation_compile_c_to_binary): Likewise.

It can be constructed - * in two ways: <ul> - * - * <li> To serve as a passthrough, sending all events to a second consumer. - * The second consumer may be identified through {@link #getNext}. - * - * <li> To serve as a dead end, with all handlers null; - * {@link #getNext} returns null. - * - * </ul> - * - * <p> Additionally, SAX handlers may be assigned, which completely replace - * the "upstream" view (through {@link EventConsumer}) of handlers, initially - * null or the "next" consumer provided to the constructor. To make - * it easier to build specialized filter classes, this class implements - * all the standard SAX consumer handlers, and those implementations - * delegate "downstream" to the consumer accessed by {@link #getNext}. - * - * <p> The simplest way to create a custom a filter class is to create a - * subclass which overrides one or more handler interface methods. The - * constructor for that subclass then registers itself as a handler for - * those interfaces using a call such as <em>setContentHandler(this)</em>, - * so the "upstream" view of event delivery is modified from the state - * established in the base class constructor. That way, - * the overridden methods intercept those event callbacks - * as they go "downstream", and - * all other event callbacks will pass events to any next consumer. - * Overridden methods may invoke superclass methods (perhaps after modifying - * parameters) if they wish to delegate such calls. Such subclasses - * should use {@link #getErrorHandler} to report errors using the - * common error reporting mechanism. - * - * <p> Another important technique is to construct a filter consisting - * of only a few specific types of handler. For example, one could easily - * prune out lexical events or various declarations by providing handlers - * which don't pass those events downstream, or by providing null handlers. - * - * <hr /> - * - * <p> This may be viewed as the consumer oriented analogue of the SAX2 - * {@link org.xml.sax.helpers.XMLFilterImpl XMLFilterImpl} class. - * Key differences include: <ul> - * - * <li> This fully separates consumer and producer roles: it - * does not implement the producer side <em>XMLReader</em> or - * <em>EntityResolver</em> interfaces, so it can only be used - * in "push" mode (it has no <em>parse()</em> methods). - * - * <li> "Extension" handlers are fully supported, enabling a - * richer set of application requirements. - * And it implements {@link EventConsumer}, which groups related - * consumer methods together, rather than leaving them separated. - * - * <li> The chaining which is visible is "downstream" to the next - * consumer, not "upstream" to the preceding producer. - * It supports "fan-in", where - * a consumer can be fed by several producers. (For "fan-out", - * see the {@link TeeConsumer} class.) - * - * <li> Event chaining is set up differently. It is intended to - * work "upstream" from terminus towards producer, during filter - * construction, as described above. - * This is part of an early binding model: - * events don't need to pass through stages which ignore them. - * - * <li> ErrorHandler support is separated, on the grounds that - * pipeline stages need to share the same error handling policy. - * For the same reason, error handler setup goes "downstream": - * when error handlers get set, they are passed to subsequent - * consumers. - * - * </ul> - * - * <p> The {@link #chainTo chainTo()} convenience routine supports chaining to - * an XMLFilterImpl, in its role as a limited functionality event - * consumer. Its event producer role ({@link XMLFilter}) is ignored. - * - * <hr /> - * - * <p> The {@link #bind bind()} routine may be used associate event pipelines - * with any kind of {@link XMLReader} that will produce the events. - * Such pipelines don't necessarily need to have any members which are - * implemented using this class.

You can use it with anything that generates SAX events, such - * as an application component that wants to detect invalid content in - * a changed area without validating an entire document, or which wants to - * ensure that it doesn't write invalid data to a communications partner.</p> - * - * <p> Also, note that because this is a layered validator, the line numbers - * reported for some errors may seem strange. For example, if an element does - * not permit character content, the validator - * will use the locator provided to it. - * That might reflect the last character of a <em>characters</em> event - * callback, rather than the first non-whitespace character. </p> - * - * <hr /> - * - * <!-- - * <p> Of interest is the fact that unlike most currently known XML validators, - * this one can report some cases of non-determinism in element content models. - * It is a compile-time option, enabled by default. This will only report - * such XML errors if they relate to content actually appearing in a document; - * content models aren't aggressively scanned for non-deterministic structure. - * Documents which trigger such non-deterministic transitions may be handled - * differently by different validating parsers, without losing conformance - * to the XML specification. </p> - * --> - * - * <p> Current limitations of the validation performed are in roughly three - * categories. </p> - * - * <p> The first category represents constraints which demand violations - * of software layering: exposing lexical details, one of the first things - * that <em>application</em> programming interfaces (APIs) hide. These - * invariably relate to XML entity handling, and to historical oddities - * of the XML validation semantics. Curiously, - * recent (Autumn 1999) conformance testing showed that these constraints are - * among those handled worst by existing XML validating parsers. Arguments - * have been made that each of these VCs should be turned into WFCs (most - * of them) or discarded (popular for the standalone declaration); in short, - * that these are bugs in the XML specification (not all via SGML): </p><ul> - * - * <li> The <em>Proper Declaration/PE Nesting</em> and - * <em>Proper Group/PE Nesting</em> VCs can't be tested because they - * require access to particularly low level lexical level information. - * In essence, the reason XML isn't a simple thing to parse is that - * it's not a context free grammar, and these constraints elevate that - * SGML-derived context sensitivity to the level of a semantic rule. - * - * <li> The <em>Standalone Document Declaration</em> VC can't be - * tested. This is for two reasons. First, this flag isn't made - * available through SAX2. Second, it also requires breaking that - * lexical layering boundary. (If you ever wondered why classes - * in compiler construction or language design barely mention the - * existence of context-sensitive grammars, it's because of messy - * issues like these.) - * - * <li> The <em>Entity Declared</em> VC can't be tested, because it - * also requires breaking that lexical layering boundary! There's also - * another issue: the VC wording (and seemingly intent) is ambiguous. - * (This is still true in the "Second edition" XML spec.) - * Since there is a WFC of the same name, everyone's life would be - * easier if references to undeclared parsed entities were always well - * formedness errors, regardless of whether they're parameter entities - * or not. (Note that nonvalidating parsers are not required - * to report all such well formedness errors if they don't read external - * parameter entities, although currently most XML parsers read them - * in an attempt to avoid problems from inconsistent parser behavior.) - * - * </ul> - * - * <p> The second category of limitations on this validation represent - * constraints associated with information that is not guaranteed to be - * available (or in one case, <em>is guaranteed not to be available</em>, - * through the SAX2 API: </p><ul> - * - * <li> The <em>Unique Element Type Declaration</em> VC may not be - * reportable, if the underlying parser happens not to expose - * multiple declarations. (Ælfred2 reports these validity - * errors directly.)</li> - * - * <li> Similarly, the <em>Unique Notation Name</em> VC, added in the - * 14-January-2000 XML spec errata to restrict typing models used by - * elements, may not be reportable. (Ælfred reports these - * validity errors directly.) </li> - * - * </ul> - * - * <p> A third category relates to ease of implementation. (Think of this - * as "bugs".) The most notable issue here is character handling. Rather - * than attempting to implement the voluminous character tables in the XML - * specification (Appendix B), Unicode rules are used directly from - * the java.lang.Character class. Recent JVMs have begun to diverge from - * the original specification for that class (Unicode 2.0), meaning that - * different JVMs may handle that aspect of conformance differently. - * </p> - * - * <p> Note that for some of the validity errors that SAX2 does not - * expose, a nonvalidating parser is permitted (by the XML specification) - * to report validity errors. When used with a parser that does so for - * the validity constraints mentioned above (or any other SAX2 event - * stream producer that does the same thing), overall conformance is - * substantially improved. - * - * @see gnu.xml.aelfred2.SAXDriver - * @see gnu.xml.aelfred2.XmlReader - * - * @author David Brownell - */ -public final class ValidationConsumer extends EventFilter -{ - // report error if we happen to notice a non-deterministic choice? - // we won't report buggy content models; just buggy instances - private static final boolean warnNonDeterministic = false; - - // for tracking active content models - private String rootName; - private Stack contentStack = new Stack (); - - // flags for "saved DTD" processing - private boolean disableDeclarations; - private boolean disableReset; - - // - // most VCs get tested when we see element start tags. the per-element - // info (including attributes) recorded here duplicates that found inside - // many nonvalidating parsers, hence dual lookups etc ... that's why a - // layered validator isn't going to be as fast as a non-layered one. - // - - // key = element name; value = ElementInfo - private Hashtable elements = new Hashtable (); - - // some VCs relate to ID/IDREF/IDREFS attributes - // key = id; value = boolean true (defd) or false (refd) - private Hashtable ids = new Hashtable (); - - // we just record declared notation and unparsed entity names. - // the implementation here is simple/slow; these features - // are seldom used, one hopes they'll wither away soon - private Vector notations = new Vector (5, 5); - private Vector nDeferred = new Vector (5, 5); - private Vector unparsed = new Vector (5, 5); - private Vector uDeferred = new Vector (5, 5); - - // note: DocBk 3.1.7 XML defines over 2 dozen notations, - // used when defining unparsed entities for graphics - // (and maybe in other places) - - - - /** - * Creates a pipeline terminus which consumes all events passed to - * it; this will report validity errors as if they were fatal errors, - * unless an error handler is assigned. - * - * @see #setErrorHandler - */ - // constructor used by PipelineFactory - // ... and want one taking system ID of an external subset - public ValidationConsumer () - { - this (null); - } - - /** - * Creates a pipeline filter which reports validity errors and then - * passes events on to the next consumer if they were not fatal. - * - * @see #setErrorHandler - */ - // constructor used by PipelineFactory - // ... and want one taking system ID of an external subset - // (which won't send declaration events) - public ValidationConsumer (EventConsumer next) - { - super (next); - - setContentHandler (this); - setDTDHandler (this); - try { setProperty (DECL_HANDLER, this); } - catch (Exception e) { /* "can't happen" */ } - try { setProperty (LEXICAL_HANDLER, this); } - catch (Exception e) { /* "can't happen" */ } - } - - - private static final String fakeRootName - = ":Nobody:in:their_Right.Mind_would:use:this-name:1x:"; - - /** - * Creates a validation consumer which is preloaded with the DTD provided. - * It does this by constructing a document with that DTD, then parsing - * that document and recording its DTD declarations.
