Examples with TypeExpression org.eclipse.persistence.jpa.jpql.parser.TypeExpression used on opensource projects

Example 1 with TypeExpression

use of org.eclipse.persistence.jpa.jpql.parser.TypeExpression in project eclipselink by eclipse-ee4j.

the class ReportItemBuilder method visit.

@Override
public void visit(TypeExpression expression) {
    Expression queryExpression = queryContext.buildExpression(expression, type);
    addAttribute(ExpressionTools.EMPTY_STRING, queryExpression);
}

Example 2 with TypeExpression

use of org.eclipse.persistence.jpa.jpql.parser.TypeExpression in project eclipselink by eclipse-ee4j.

the class AbstractSemanticValidator method validateTypeExpression.

/**
 * Validates the given {@link TypeExpression}. The test to perform is:
 * <ul>
 *    <li>If the encapsulated expression is a path expression, validation makes sure it is an
 *        association field, a basic field is not allowed.</li>
 * </ul>
 *
 * @param expression The {@link TypeExpression} to validate
 * @return <code>false</code> if the encapsulated expression was validated and is invalid;
 * <code>true</code> otherwise
