Packages that use org.eclipse.persistence.jpa.jpql

Package	Description
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.
org.eclipse.persistence.jpa.jpql.parser	This is the core of Hermes, this package contains the classes that can parse a JPQL query.

Classes in org.eclipse.persistence.jpa.jpql used by org.eclipse.persistence.jpa.jpql

Class	Description
AbstractEclipseLinkSemanticValidator.EclipseLinkOwningClauseVisitor	This visitor retrieves the clause owning the visited Expression.
AbstractEclipseLinkSemanticValidator.SubquerySelectItemCalculator
AbstractEclipseLinkSemanticValidator.TableExpressionVisitor
AbstractEclipseLinkSemanticValidator.TopLevelFirstDeclarationVisitor
AbstractGrammarValidator	The base validator responsible to gather the problems found in a JPQL query by validating it against the provided JPQL grammar.
AbstractGrammarValidator.AbstractCollectionValidator	This validate is responsible to validate the collection of Expressions: Making sure they are all separated by a comma or by a space (depending on which one is required); Making sure it does not end with a comma; There is no empty expression between two commas.
AbstractGrammarValidator.AbstractDoubleEncapsulatedExpressionHelper
AbstractGrammarValidator.AbstractEncapsulatedExpressionHelper	The root helper that validates any AbstractEncapsulatedExpression.
AbstractGrammarValidator.AbstractSingleEncapsulatedExpressionHelper	The abstract implementation of AbstractGrammarValidator.AbstractSingleEncapsulatedExpressionHelper which implements some of the methods since the behavior is the same for all subclasses of AbstractSingleEncapsulatedExpression.
AbstractGrammarValidator.AbstractTripleEncapsulatedExpressionHelper
AbstractGrammarValidator.CollectionExpressionVisitor	This visitor retrieves the CollectionExpression if it is visited.
AbstractGrammarValidator.CollectionSeparatedByCommaValidator	This validator validates a CollectionExpression by making sure each item is separated by a comma.
AbstractGrammarValidator.CollectionSeparatedBySpaceValidator	This validator validates a CollectionExpression by making sure each item is not separated by a comma.
AbstractGrammarValidator.ComparisonExpressionVisitor
AbstractGrammarValidator.DateTimeVisitor
AbstractGrammarValidator.NullExpressionVisitor	This visitor checks to see if the visited expression is NullExpression.
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.
AbstractSemanticValidator.CollectionValuedPathExpressionVisitor	This visitor is meant to retrieve an CollectionValuedPathExpression if the visited Expression is that object.
AbstractSemanticValidator.ComparingEntityTypeLiteralVisitor
AbstractSemanticValidator.ComparisonExpressionVisitor	This visitor compares the left and right expressions of a comparison expression and gathers information about those expressions if they are an identification variable or a path expression.
AbstractSemanticValidator.FirstDeclarationVisitor
AbstractSemanticValidator.InItemsVisitor
AbstractSemanticValidator.PathType	This enumeration allows AbstractSemanticValidator.validateStateFieldPathExpression( StateFieldPathExpression, PathType) to validate the type of the mapping and to make sure it is allowed based on its location.
AbstractSemanticValidator.StateFieldPathExpressionVisitor	This visitor is meant to retrieve an AbstractSemanticValidator.StateFieldPathExpressionVisitor if the visited Expression is that object.
AbstractSemanticValidator.SubqueryFirstDeclarationVisitor
AbstractSemanticValidator.TopLevelFirstDeclarationVisitor
AbstractValidator	The abstract definition of a validator, which provides helper methods and visitors.
AbstractValidator.BypassChildCollectionExpressionVisitor	This visitor is responsible to traverse the children of a CollectionExpression in order to properly validate the Expression.
AbstractValidator.BypassParentSubExpressionVisitor	This visitor is responsible to traverse the parent hierarchy and to skip SubExpression if it's a parent.
AbstractValidator.ChildrenCollectorVisitor	This visitor gathers the children of a CollectionExpression or a single visited Expression.
AbstractValidator.JPQLQueryBNFValidator	This visitor validates any Expression by checking its BNF against some BNFs.
AbstractValidator.NestedArrayVisitor
AbstractValidator.OwningClauseVisitor	This visitor retrieves the clause owning the visited Expression.
AbstractValidator.OwningStatementVisitor	This visitor retrieves the statement owning the visited Expression.
AbstractValidator.SubqueryVisitor	This visitor retrieves the statement owning the visited Expression.
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.
EclipseLinkGrammarValidator	This validator adds EclipseLink extension over what the JPA functional specification had defined.
EclipseLinkGrammarValidator.InExpressionVisitor
EclipseLinkGrammarValidator.InExpressionWithNestedArrayVisitor
EclipseLinkSemanticValidatorExtension	This extension provides additional support to semantic validation by adding support for non-JPA specific artifacts, such as database objects.
EclipseLinkVersion	An enumeration listing the various releases of EclipseLink.
ITypeHelper
JPAVersion	An enumeration listing the various releases of the Java Persistence specification.
JPQLQueryDeclaration	A JPQLQueryDeclaration represents either an identification variable declaration or a collection member declaration.
JPQLQueryDeclaration.Type	This enum type defines the various types of declarations supported by both the JPA functional specification and EclipseLink.
JPQLQueryProblem	A problem describes an issue found in a JPQL query because it is either grammatically or semantically incorrect.
LiteralType	Some Expression can have a "literal", this enumeration is used to visit an Expression and to retrieve the right value.
LiteralVisitor	This visitor traverses an Expression and retrieves the "literal" value.
ParameterTypeVisitor	This visitor calculates the type of an input parameter.
SemanticValidatorHelper	This helper is used by AbstractSemanticValidator in order to retrieve JPA information.
WordParser	This "parser/scanner" holds onto the string version of the JPQL query that is parsed into a parsed tree.
WordParser.WordType	This enumeration determines the type of word that was scanned.
