public class EclipseLinkRefactoringTool
extends RefactoringTool

This refactoring tool add support for EclipseLink specific extension over the default implementation of JPQL defined in the Java Persistence functional specification.

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.

Since:

2.4

Version:

2.4

Constructor Details

EclipseLinkRefactoringTool

public EclipseLinkRefactoringTool(IManagedTypeProvider managedTypeProvider,
 IJPQLQueryBuilder jpqlQueryBuilder,
 CharSequence jpqlQuery)

Creates a new EclipseLinkRefactoringTool.

Parameters:

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

jpqlQueryBuilder - The builder that creates the StateObject representation of the JPQL query

jpqlQuery - The JPQL query to manipulate

EclipseLinkRefactoringTool

public EclipseLinkRefactoringTool(IManagedTypeProvider managedTypeProvider,
 IJPQLQueryBuilder jpqlQueryBuilder,
 CharSequence jpqlFragment,
 String jpqlQueryBNFId)

Creates a new EclipseLinkRefactoringTool.

Parameters:

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

jpqlQueryBuilder - The builder that creates the StateObject representation of the JPQL query

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

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

Method Details

buildFormatter

protected IJPQLQueryFormatter buildFormatter()

Description copied from class: RefactoringTool

Creates a new formatter that will convert the StateObject representation of the JPQL query, once the refactoring occurred into a string.

Specified by:

buildFormatter in class RefactoringTool

Returns:

A new concrete instance of IJPQLQueryFormatter

buildJPQLQueryContext

protected JPQLQueryContext buildJPQLQueryContext()

Description copied from class: RefactoringTool

Creates a new JPQLQueryContext that can retrieve information from the declaration portion of the JPQL query.

NOTE: This is temporary because the StateObject API does not have that knowledge yet.

Specified by:

buildJPQLQueryContext in class RefactoringTool

Returns:

A new concrete instance of JPQLQueryContext
