Interface Summary

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

Class Summary

Modifier and Type	Class and Description
public class	ASTQueryTranslatorFactory Generates translators which uses the Antlr-based parser to perform the translation.
public class	DetailedSemanticException Thrown when a call to the underlying Hibernate engine fails, indicating some form of semantic exception (e.g. a class name was not found in the current mappings, etc.).
public class	ErrorTracker An error handler that counts parsing errors and warnings.
public class	HqlASTFactory User: Joshua Davis Date: Sep 23, 2005 Time: 12:30:01 PM
pack-priv class	HqlLexer Custom lexer for the HQL grammar.
public class	HqlParser Implements the semantic action methods defined in the HQL base parser to keep the grammar source file a little cleaner.
public class	HqlSqlWalker Implements methods used by the HQL->SQL tree transform grammar (a.k.a. the second phase).
public class	HqlToken A custom token class for the HQL grammar.
public class	InvalidPathException Exception thrown when an invalid path is found in a query.
public class	InvalidWithClauseException Indicates an issue with the encountered with-clause.
public class	NamedParameterInformationImpl
public class	ParameterTranslationsImpl Defines the information available for parameters encountered during query translation through the antlr-based parser.
public class	PositionalParameterInformationImpl
public class	QuerySyntaxException Exception thrown when there is a syntax error in the HQL.
public class	QueryTranslatorImpl A QueryTranslator that uses an Antlr-based parser.
public class	SqlASTFactory Custom AST factory the intermediate tree that causes ANTLR to create specialized AST nodes, given the AST node type (from HqlSqlTokenTypes).
public class	SqlGenerator Generates SQL by overriding callback methods in the base class, which does the actual SQL AST walking.
