An ANTLR-based parser for Hibernate Query Language.

Interface Summary

Interface	Description
ErrorReporter	Implementations will report or handle errors invoked by an ANTLR base parser.
ParseErrorHandler	Defines the behavior of an error handler for the HQL parsers.
TypeDiscriminatorMetadata	Essentially a wrapper around a DiscriminatorMetadata and the proper sql alias to use.

Class Summary

Class	Description
ASTQueryTranslatorFactory	Generates translators which uses the Antlr-based parser to perform the translation.
ErrorTracker	An error handler that counts parsing errors and warnings.
HqlASTFactory	User: Joshua Davis Date: Sep 23, 2005 Time: 12:30:01 PM
HqlParser	Implements the semantic action methods defined in the HQL base parser to keep the grammar source file a little cleaner.
HqlSqlWalker	Implements methods used by the HQL->SQL tree transform grammar (a.k.a.
HqlToken	A custom token class for the HQL grammar.
NamedParameterInformationImpl
ParameterTranslationsImpl	Defines the information available for parameters encountered during query translation through the antlr-based parser.
PositionalParameterInformationImpl
QueryTranslatorImpl	A QueryTranslator that uses an Antlr-based parser.
QueryTranslatorImpl.JavaConstantConverter
SqlASTFactory	Custom AST factory the intermediate tree that causes ANTLR to create specialized AST nodes, given the AST node type (from HqlSqlTokenTypes).
SqlGenerator	Generates SQL by overriding callback methods in the base class, which does the actual SQL AST walking.

Exception Summary

Exception	Description
DetailedSemanticException	Thrown when a call to the underlying Hibernate engine fails, indicating some form of semantic exception (e.g.
InvalidPathException	Exception thrown when an invalid path is found in a query.
InvalidWithClauseException	Indicates an issue with the encountered with-clause.
QuerySyntaxException	Exception thrown when there is a syntax error in the HQL.
