Examples of WordParser

org.eclipse.persistence.jpa.internal.jpql.WordParser
This "parser" holds onto the string version of the Java Persistence query that is parsed into a parsed tree. It uses a cursor that let the current {@link Expression} object to parse its sectionof the query. @version 2.3 @since 2.3 @author Pascal Filion
org.eclipse.persistence.jpa.jpql.WordParser
This "parser/scanner" holds onto the string version of the JPQL query that is parsed into a parsed tree. It uses a cursor that lets the current {@link org.eclipse.persistence.jpa.jpql.parser.Expression Expression} object to parse its fragment of the query.
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. @version 2.4.2 @since 2.3 @author Pascal Filion
