@author Bertoli Marco @version 1.0Questions as to whether a semicolon should be inserted can only be answered at the lexical level. A lexer can emit a comment-like-token where semicolons can be inserted though this is not the approach taken in this implementation.

This is NOT part of any supported API. If you write code that depends on this, you do so at your own risk. This code and its internal interfaces are subject to change or deletion without notice.
This conforms to the XML 1.0 specification. To configure an XML processor which tests document conformance against XML Namespaces, provide a DtdEventListener which examines declarations of entities and notations, and have your document listener check other constraints such as ensuring xmlns* attribute values properly declare all namespace prefixes. (Only element and attribute names may contain colons, and even then the name prefix before the colon must be properly declared.)
SAX parsers produce a stream of parse events, which applications process to create an object model which is specific to their tasks. Applications which do not want to process event streams in that way should use an API producing a standardized object model, such as the W3C's Document Object Model (DOM). This parser supports building fully conformant DOM Document objects, through use of DtdEventListener extensions to SAX in conjunction with an appropriate implementation of a SAX DocumentHandler. In addition, it supports some features (exposing comments, CDATA sections, and entity references) which are allowed by DOM but not required to be reported by conformant XML processors. (As usual, the default handler for parsing events other than fatal errors ignores them.) @see ValidatingParser @author David Brownell @version $Revision: 1.13 $

These unary functions are defined: abs, acos, asin, atan, ceil, cos, exp, floor, log, round, sin, sqrt, tan. Each requires one argument enclosed in parentheses.
There are also binary functions: atan2, min, max; and a ternary conditional function: if(test, then, else).
Whitespace outside identifiers is ignored.
Examples:
private static final String [][] syntax = { { "Start", "\"Hello\"", "\"World\"" }, { Token.IGNORED, "`whitespaces`" }, }; SyntaxSeparation separation = new SyntaxSeparation(new Syntax(syntax)); LexerBuilder builder = new LexerBuilder(separation.getLexerSyntax(), separation.getIgnoredSymbols()); Lexer lexer = builder.getLexer(); lexer.setInput("\tHello \r\n\tWorld\n"); ParserTables parserTables = new SLRParserTables(separation.getParserSyntax()); Parser parser = new Parser(parserTables); parser.parse(lexer, new PrintSemantic()); TODO: implement error recovery: method recover()

L'operazione fondamentale svolta da un Parser e' quella di 'leggere' una stringa ed estrapolare da essa le componenti di interesse (segnalate mediante la Regex genitrice).

The parser generates an {@link AstRoot} parse tree representing the sourcecode. No tree rewriting is permitted at this stage, so that the parse tree is a faithful representation of the source for frontend processing tools and IDEs.
This parser implementation is not intended to be reused after a parse finishes, and will throw an IllegalStateException() if invoked again.

parse to transform serialized RDF forms into {@link Graph}s. Functionality is delegated to registered {@link ParsingProvider}s. Such ParsingProviders can be registered and unregistered, later registered ParsingProviders shadow previously registered providers for the same format. Note on synchronization: ParsingProviders must be able to handle concurrent requests.

This class is automatically generated, so, it might be non-obvious to determine how to use it. To create a new parser and parse a document, do the following:
InputSource source = new InputSource(...);
Parser parser = new Parser();
Events events = parser.parse(source);
Note that instances of this class are NOT THREAD SAFE, meaning that two threads cannot concurrently parse two documents using the same instance, but at the same time, one thread can safely call the parse(...) method several times (the parser will automatically re-initialize its state once the method is invoked).
This interface is used in two complementary ways:
Whatever the class that implements this interface, it must also expose either a public no-arg constructor, or (for implementations that also are Facets) a public constructor that accepts a single FacetHolder. This constructor allows the framework to instantiate the object reflectively. @see DefaultsProvider @see EncoderDecoder @see ValueSemanticsProvider
Describe your class here
.Parses the document into a tree of nodes using the {@link NodeTokenizer}. Nodes are defined by a token or offset range in the document, {@link Token}. Attributes in beginning nodes are also parsed into token offsets by the {@link AttributeTokenizer}.
A document tree is built representing nodes in the target document. The document can be a HTML fragment that is not well-formed or an XML fragment of a XHTML document.
A Rule has a priority. If a HTTP request matches the Rule, parser returns the priority corresponding to that rule.
Here is the syntax of the configuration used to building the parser
<conditions [defualtPriority = "int"]> <condition priority = ""> <and/> | <or> | <not> | <match> | <equal> </condition> </conditions>
Parser returns a list of issues it finds in the text area's content, which the text area can flag (e.g. squiggle underline). It can also return descriptions of the issues, to be used in tool tips.

This parser uses a sax based driver to parse an input stream into a single object. For streaming look at {@link StreamingParser}. If the source document being parsed as already been parsed into a {@link Document} the {@link DOMParser} class may be used.
Parser parser = new Parser("http://www.yahoo.com",new DefaultHTMLParserFeedback()); // In this example, none of the scanners need to be registered // as a string node is not a tag to be scanned for. for (NodeIterator i = parser.elements();e.hasMoreNodes();) { Node node = i.nextNode(); if (node instanceof StringNode) { StringNode stringNode = (StringNode)node; System.out.println(stringNode.getText()); } } The above snippet will print out only the text contents in the html document. Parser parser = new Parser("http://www.yahoo.com",new DefaultHTMLParserFeedback()); parser.addScanner(new LinkScanner("-l")); for (NodeIterator i = parser.elements();e.hasMoreNodes();) { Node node = i.nextNode(); if (node instanceof LinkTag) { LinkTag linkTag = (LinkTag)node; System.out.println(linkTag.getLink()); } }
@see Parser#elements()
Then, activity bindings might access the processDefinition like this:
public class MyNodeBinding implements Binding { public Object parse(Element element, Parse parse, Parser parser) { // instantiate the object for this binding MyNode myNode = new MyNode(); // add the activity to the processDefinition MyProcess myProcess = parse.findObject(MyProcess.class); myProcess.addNode(myNode); myNode.setMyProcess(myProcess); return myNode; } } A parser implementation will typically have a static Bindings object that is leveraged in all parser objects. To customize bindings for a such a parser be sure to make a deep copy with {@link Bindings#Bindings(Bindings)} beforeyou start adding more bindings to the specialized parser. Otherwise the base parser's bindings will be updated as well.
This parser is build for inheritance. Overriding method {@link #parseDocumentElement(Element,Parse)} can be an easy way to start writing your own logic on walking the Document Object Model (DOM). Such customizations can still be combined with the usage of bindings.
A parser can be configured with a set of entities with the {@link #addEntity(String,Entity)} method. The {@link UrlEntity} hasa convenience method to build entities from resources {@link UrlEntity#UrlEntity(String,ClassLoader)}.
When a document builder is created, the default implementation of the {@link #setEntityResolver(DocumentBuilder)} will set this parser as the entity resolver.The implementation method of {@link EntityResolver} ({@link #resolveEntity(String,String)}will use the added {@link Entity}s to try and find a match based on the publicId. If one is found, the {@link Entity} inputSource is returned, otherwisethe systemId is used.
This class is intended to be used with aggregation as well as inheritence.

All CSS parsers must implement this basic interface: it allows applications to register handlers for different types of events and to initiate a parse from a URI, or a character stream.
All CSS parsers must also implement a zero-argument constructor (though other constructors are also allowed).
CSS parsers are reusable but not re-entrant: the application may reuse a parser object (possibly with a different input source) once the first parse has completed successfully, but it may not invoke the parse() methods recursively within a parse.
@version $Revision: 1.3 $ @author Philippe Le Hegaret @see DocumentHandler @see ErrorHandler @see InputSourceThis was the main event supplier interface for SAX1; it has been replaced in SAX2 by {@link org.xml.sax.XMLReader XMLReader}, which includes Namespace support and sophisticated configurability and extensibility.

The parser should be reset at the end of every game to clear the symbol table.
I'm not sure if it's actually necessary to reset the parser. Why not just let the symbol table grow? We have 2^31-256 values, so we'll only have overflow issues after seeing that many unique tokens. We should only get new tokens during game initializations. Assuming that every game creates 5,000 new tokens, we would need to play on the order of 429,496 games to fill up our symbol table... @author Based on code by Team Camembert: David Haley, Pierre-Yves Laligand
