Interface Summary

Interface	Description
IAbstractConditionalExpressionStateObjectBuilder<T extends IScalarExpressionStateObjectBuilder<T>>
IBuilder<T extends StateObject,S extends StateObject>	This builder is used by BasicStateObjectBuilder, which allows subclasses to easily change any internal builders used for properly creating the state model representation of a JPQL query.
ICaseExpressionStateObjectBuilder	This builder is responsible to create a CASE expression.
IConditionalExpressionStateObjectBuilder	This builder can be used to easily create a conditional expression without having to create each object manually.
IEclipseLinkConditionalStateObjectBuilder	The EclipseLink extension over the basic support provided by IEclipseLinkConditionalStateObjectBuilder.
IEclipseLinkSelectExpressionStateObjectBuilder
IEclipseLinkSimpleSelectExpressionStateObjectBuilder
IJPQLQueryBuilder	This builder is responsible to create an editable StateObject representation of a JPQL query.
IJPQLQueryFormatter	A IJPQLQueryFormatter helps to write a string representation of a StateObject.
IListChangeEvent<T>	This is used in conjunction with IListChangeListener.
IListChangeListener<T>	A IListChangeListener can be registered with a StateObject in order to be notified when a list changes (items are added or removed from it or some items have been moved inside of that list).
INewValueStateObjectBuilder
IPropertyChangeEvent<T>	This is used in conjunction with IPropertyChangeListener.
IPropertyChangeListener<T>	A IPropertyChangeListener can be registered with a StateObject in order to be notified when the value of a property changes.
IScalarExpressionStateObjectBuilder<T extends IScalarExpressionStateObjectBuilder<T>>	This builder can be used to easily create a scalar expression without having to create each object manually.
ISelectExpressionStateObjectBuilder	This builder can be used to easily create a select expression without having to create each object manually.
ISimpleSelectExpressionStateObjectBuilder	This builder can be used to easily create a select expression defined for a subquery without having to create each object manually.
Problem	A problem describes an issue found in a JPQL query because it is either grammatically or semantically incorrect.

Class Summary

Class	Description
AbstractActualJPQLQueryFormatter	This IJPQLQueryFormatter is used to generate a string representation of a StateObject based on how it was parsed, which means this formatter can only be used when the StateObject was created by parsing a JPQL query because it needs to retrieve parsing information from the corresponding Expression.
AbstractCaseExpressionStateObjectBuilder	This abstract implementation of ICaseExpressionStateObjectBuilder adds support for creating a CASE expression.
AbstractConditionalExpressionStateObjectBuilder<T extends IAbstractConditionalExpressionStateObjectBuilder<T>>	The abstract implementation of IConditionalExpressionStateObjectBuilder that supports the creation of the conditional expression based on the JPQL grammar defined in JPA 2.0.
AbstractConditionalStateObjectBuilderWrapper	This builder wraps another builder and delegates the calls to it.
AbstractEclipseLinkSelectExpressionStateObjectBuilder
AbstractEclipseLinkSimpleSelectExpressionStateObjectBuilder
AbstractJPQLQueryBuilder	An abstract implementation of IJPQLQueryBuilder that parses a JPQL query or any JPQL fragments and creates the StateObject representation by delegating the creation to an instance of BasicStateObjectBuilder.
AbstractJPQLQueryFormatter	The abstract definition of a IJPQLQueryFormatter, which converts an StateObject into its string representation that can be used as a real JPQL query.
AbstractNewValueStateObjectBuilder
AbstractScalarExpressionStateObjectBuilder<T extends IScalarExpressionStateObjectBuilder<T>>	This abstract definition of a builder provides the support for creating expressions defined by a scalar expression.
AbstractSelectExpressionStateObjectBuilder
AbstractSimpleSelectExpressionStateObjectBuilder	The abstract implementation of ISimpleSelectExpressionStateObjectBuilder that supports the creation of the select expression based on the JPQL grammar defined in JPA 2.0.
AbstractStateObjectBuilder	The abstract definition of a builder of a StateObject hierarchy based on a JPQL fragment that is manually created.
BaseJPQLQueryFormatter	An abstract implementation of a IJPQLQueryFormatter.
BasicStateObjectBuilder	The default implementation of a IBuilder, which creates a StateObject representation of the Expression being visited.
DefaultActualJPQLQueryFormatter	This IJPQLQueryFormatter is used to generate a string representation of a StateObject based on how it was parsed, which means this formatter can only be used when the {@link org.eclipse.persistence.jpa.jpql.
DefaultCaseExpressionStateObjectBuilder	The default implementation of a ICaseExpressionStateObjectBuilder.
DefaultConditionalExpressionStateObjectBuilder	The default implementation of IConditionalExpressionStateObjectBuilder.
DefaultEclipseLinkJPQLQueryBuilder	An implementation of IJPQLQueryBuilder that provides support based on the latest release of the Java Persistence functional specification.
DefaultJPQLQueryBuilder	An implementation of IJPQLQueryBuilder that provides support based on the latest release of the Java Persistence functional specification.
DefaultJPQLQueryFormatter	The default implementation of a IJPQLQueryFormatter, which support creating a string representation of a JPQL query written for JPA 1.0 and 2.0.
DefaultNewValueStateObjectBuilder	The default implementation of INewValueStateObjectBuilder.
DefaultProblem	The default implementation of Problem.
DefaultSelectExpressionStateObjectBuilder
DefaultSimpleSelectExpressionStateObjectBuilder
DefaultStateObjectBuilder	The default implementation of BasicStateObjectBuilder, which provides support for creating a StateObject representation of any Expression.
EclipseLinkActualJPQLQueryFormatter	This IJPQLQueryFormatter is used to generate a string representation of a StateObject based on how it was parsed, which means this formatter can only be used when the {@link org.eclipse.persistence.jpa.jpql.
EclipseLinkConditionalStateObjectBuilder	The EclipseLink extension over the basic support provided by IConditionalExpressionStateObjectBuilder.
EclipseLinkJPQLQueryBuilder	An implementation of IJPQLQueryBuilder that provides support based on the release of the Java Persistence functional specification defined in	EclipseLinkJPQLQueryFormatter	The default implementation of a IJPQLQueryFormatter that adds support for formatting EclipseLink specific JPQL identifiers.
EclipseLinkSelectExpressionStateObjectBuilder
EclipseLinkSimpleSelectExpressionStateObjectBuilder
EclipseLinkStateObjectBuilder	The default implementation of BasicStateObjectBuilder, which provides support based on the JPQL grammar defined in the Java Persistence functional specification and for the additional support provided by EclipseLink.
JPQLQueryBuilder1_0	An implementation of IJPQLQueryBuilder that provides support based on the Java Persistence functional specification defined in	JPQLQueryBuilder2_0	An implementation of IJPQLQueryBuilder that provides support based on the Java Persistence functional specification defined in	JPQLQueryBuilder2_1	An implementation of IJPQLQueryBuilder that provides support based on the Java Persistence functional specification defined in	JPQLQueryBuilderWrapper	This builder wraps another builder and simply delegates the calls to it.
ListChangeEvent<T>	The default implementation of IListChangeListener where the generics is the type of the items.
PropertyChangeEvent<T>	The default implementation of IPropertyChangeEvent where the generics is the type of the old and new values.
