org.apache.olingo.odata2.jpa.processor.api.jpql.JPQLStatement

The class represents a Java Persistence Query Language (JPQL) Statement. The JPQL statement is built using a builder namely {@link org.apache.olingo.odata2.jpa.processor.api.jpql.JPQLStatement.JPQLStatementBuilder} . Based upon the JPQLContext types ( {@link org.apache.olingo.odata2.jpa.processor.api.jpql.JPQLContextType} differentkinds of JPQL statements are built. The JPQL statements thus generated can be executed using JPA Query APIs to fetch JPA entities. @see org.apache.olingo.odata2.jpa.processor.api.factory.JPQLBuilderFactory @see org.apache.olingo.odata2.jpa.processor.api.jpql.JPQLContextView
