Example 1 with UnsupportedTypeException

use of org.apache.asterix.om.exceptions.UnsupportedTypeException in project asterixdb by apache.

the class RecordRemoveFieldsTypeComputer method getPathFromConstantExpression.

private void getPathFromConstantExpression(String funcName, ILogicalExpression expression, Set<String> fieldNameSet, List<List<String>> pathList) throws AlgebricksException {
    ConstantExpression ce = (ConstantExpression) expression;
    if (!(ce.getValue() instanceof AsterixConstantValue)) {
        throw new InvalidExpressionException(funcName, 1, ce, LogicalExpressionTag.CONSTANT);
    }
    IAObject item = ((AsterixConstantValue) ce.getValue()).getObject();
    ATypeTag type = item.getType().getTypeTag();
    switch(type) {
        case STRING:
            String fn = ((AString) item).getStringValue();
            fieldNameSet.add(fn);

        case ARRAY:
            AOrderedList pathOrdereList = (AOrderedList) item;
            String fieldName = ((AString) pathOrdereList.getItem(0)).getStringValue();
