/**
 * This {@link IJPQLQueryFormatter} is used to generate a string representation of a {@link
 * org.eclipse.persistence.jpa.jpql.tools.model.query.StateObject StateObject} based on how it was parsed,
 * which means this formatter can only be used when the
 * {@link org.eclipse.persistence.jpa.jpql.tools.model.query.StateObject StateObject} was created by parsing a JPQL
 * query because it needs to retrieve parsing information from the corresponding
 * {@link org.eclipse.persistence.jpa.jpql.parser.Expression Expression}.
 * <p>
 * It is possible to partially match the JPQL query that was parsed, the value of the <em>exactMatch</em>
 * will determine whether the string representation of any given
 * {@link org.eclipse.persistence.jpa.jpql.tools.model.query.StateObject StateObject} should reflect the exact string
 * that was parsed. <code>true</code> will use every bit of information contained in the corresponding {@link
 * org.eclipse.persistence.jpa.jpql.parser.Expression Expression} to perfectly match what was parsed;
 * <code>false</code> will only match the case sensitivity of the JPQL identifiers.
