public class EclipseLinkBasicRefactoringTool
extends BasicRefactoringTool

This utility class provides basic refactoring support. This version adds support for EclipseLink specific extension over the default implementation of JPQL defined in the Java Persistence functional specification and it does not changes the StateObject but rather gather the changes in RefactoringDelta and it is the responsibility of the invoker to the actual change.

Provided functionality:

• Renaming an identification variable;
• Renaming a state field or collection-valued field;
• Renaming an entity name;
• Renaming a Class name (e.g.: in constructor expression);
• Renaming an Enum constant.

Provisional API: This interface is part of an interim API that is still under development and expected to change significantly before reaching stability. It is available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.

Constructor Detail

EclipseLinkBasicRefactoringTool

public EclipseLinkBasicRefactoringTool(java.lang.CharSequence jpqlQuery,
                                       JPQLGrammar jpqlGrammar,
                                       IManagedTypeProvider managedTypeProvider)

Creates a new EclipseLinkBasicRefactoringTool.

Parameters:

jpqlQuery - The JPQL query to manipulate

jpqlGrammar - The JPQLGrammar that was used to parse the JPQL query

managedTypeProvider - The external form of a provider that gives access to the JPA metadata

EclipseLinkBasicRefactoringTool

public EclipseLinkBasicRefactoringTool(java.lang.CharSequence jpqlFragment,
                                       JPQLGrammar jpqlGrammar,
                                       IManagedTypeProvider managedTypeProvider,
                                       java.lang.String jpqlQueryBNFId)

Creates a new EclipseLinkBasicRefactoringTool.

Parameters:

jpqlFragment - The JPQL query to manipulate or a single JPQL fragment, which is parsed using the JPQL query BNF identifier by the given ID

jpqlGrammar - The JPQLGrammar that was used to parse the JPQL fragment

managedTypeProvider - The external form of a provider that gives access to the JPA metadata

jpqlQueryBNFId - The unique identifier of the JPQLQueryBNF that determines how to parse the JPQL fragment
