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

Example 1 with CastExpression

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

the class EclipseLinkContentAssistVisitor method visit.

@Override
public void visit(CastExpression expression) {
    super.visit(expression);
    int position = queryPosition.getPosition(expression) - corrections.peek();
    String identifier = expression.getIdentifier();
    // Within CAST
    if (isPositionWithin(position, identifier)) {
        addIdentifier(identifier);
        addIdentificationVariables();
        addFunctionIdentifiers(expression.getParent().findQueryBNF(expression));
    } else // After "CAST("
    if (expression.hasLeftParenthesis()) {
        int length = identifier.length() + 1;
        // Right after "CAST("
        if (position == length) {
            addIdentificationVariables();
            addFunctionIdentifiers(expression.getEncapsulatedExpressionQueryBNFId());
        } else if (expression.hasExpression()) {
            Expression scalarExpression = expression.getExpression();
            if (isComplete(scalarExpression)) {
                length += scalarExpression.getLength();
                if (expression.hasSpaceAfterExpression()) {
                    length++;
                    // Right before "AS" or database type
                    if (position == length) {
                        addAggregateIdentifiers(expression.getEncapsulatedExpressionQueryBNFId());
                        proposals.addIdentifier(AS);
                    } else // Within "AS"
                    if (isPositionWithin(position, length, AS)) {
                        proposals.addIdentifier(AS);
                    }
