module org.eclipse.persistence.jpa.jpql

Package org.eclipse.persistence.jpa.jpql

This package contains the Hermes features (except the parser itself): semantic and grammatical validations, content assist support, calculating the query result type or the possible type of an input parameter, refactoring tools.

Interface Summary

Modifier and Type	Interface and Description
public interface	EclipseLinkSemanticValidatorExtension This extension provides additional support to semantic validation by adding support for non-JPA specific artifacts, such as database objects.
public interface	ITypeHelper
public interface	JPQLQueryDeclaration A `JPQLQueryDeclaration` represents either an identification variable declaration or a collection member declaration.
public interface	JPQLQueryProblem A problem describes an issue found in a JPQL query because it is either grammatically or semantically incorrect.
public interface	JPQLQueryProblemMessages The list of messages used by `JPQLQueryProblems` when validating a JPQL query.
public interface	SemanticValidatorHelper This helper is used by `AbstractSemanticValidator` in order to retrieve JPA information.

Class Summary

Modifier and Type	Class and Description
public abstract class	AbstractEclipseLinkParameterTypeVisitor This visitor calculates the type of an input parameter.
public class	AbstractEclipseLinkSemanticValidator This validator is responsible to gather the problems found in a JPQL query by validating the content to make sure it is semantically valid for EclipseLink.
public abstract class	AbstractGrammarValidator The base validator responsible to gather the problems found in a JPQL query by validating it against the provided JPQL grammar.
public abstract class	AbstractSemanticValidator The base validator responsible to gather the problems found in a JPQL query by validating the content to make sure it is semantically valid, i.e. based on the information contained in the JPA application.
public abstract class	AbstractValidator The abstract definition of a validator, which provides helper methods and visitors.
public class	Assert An utility class that provides various checks and when the condition fails, then an `AssertException` is thrown.
public class	BaseDeclarationIdentificationVariableFinder This visitor traverses the parsed tree and retrieves the `IdentificationVariable` defined in the base range variable declaration for the top-level statement if and only if the query is a `DELETE` or `UPDATE` query.
pack-priv class	DefaultJPQLQueryProblem The default implementation of `JPQLQueryProblem`.
public class	EclipseLinkGrammarValidator This validator adds EclipseLink extension over what the JPA functional specification had defined.
public class	EclipseLinkLiteralVisitor This visitor traverses an `Expression` and retrieves the "literal" value.
public class	ExpressionTools A utility class containing various methods related to the Hermes parser.
public class	JPQLQueryProblemResourceBundle The resource bundle containing the problems encountered in a JPQL query.
public abstract class	LiteralVisitor This visitor traverses an `Expression` and retrieves the "literal" value.
public abstract class	ParameterTypeVisitor This visitor calculates the type of an input parameter.
public class	WordParser This "parser/scanner" holds onto the string version of the JPQL query that is parsed into a parsed tree.

Enum Summary

Modifier and Type	Enum and Description
public enum	EclipseLinkVersion An enumeration listing the various releases of EclipseLink.
public enum	JPAVersion An enumeration listing the various releases of the Java Persistence specification.
public enum	LiteralType Some `Expression` can have a "literal", this enumeration is used to visit an `Expression` and to retrieve the right value.
