Example 1 with AssignExprT

use of org.drools.mvelcompiler.ast.AssignExprT in project drools by kiegroup.

the class LHSPhase method withBigDecimalConversion.

// Conversion of AssignExpr to BigDecimal Arithmetic operation when LHS is is a BigDecimal variable
public Optional<TypedExpression> withBigDecimalConversion(AssignExpr assignExpr, TypedExpression target, TypedExpression value) {
    Optional<Type> optRHSType = value.getType();
    if (!optRHSType.isPresent()) {
        return Optional.empty();
    }
    AssignExpr.Operator operator = assignExpr.getOperator();
    if (operator == AssignExpr.Operator.ASSIGN) {
        return Optional.empty();
    }
    // handled previously in FieldAccessExpr visitor
    boolean assigningToFieldAccess = target instanceof FieldToAccessorTExpr;
    if (!assigningToFieldAccess && target.getType().filter(t -> t == BigDecimal.class).isPresent()) {
        String bigDecimalMethod = BigDecimalArithmeticExprT.toBigDecimalMethod(operator);
        BigDecimalArithmeticExprT convertedBigDecimalExpr = new BigDecimalArithmeticExprT(bigDecimalMethod, target, value);
        return Optional.of(new AssignExprT(AssignExpr.Operator.ASSIGN, target, convertedBigDecimalExpr));
    }
    return Optional.empty();
}
