示例1: generateTupleSchema
TupleSchema* AbstractPlanNode::generateTupleSchema(const std::vector<SchemaColumn*>& outputSchema)
{
int schema_size = static_cast<int>(outputSchema.size());
vector<voltdb::ValueType> columnTypes;
vector<int32_t> columnSizes;
vector<bool> columnAllowNull(schema_size, true);
vector<bool> columnInBytes;
for (int i = 0; i < schema_size; i++)
{
//TODO: SchemaColumn is a sad little class that holds an expression pointer,
// a column name that only really comes in handy in one quirky special case,
// (see UpdateExecutor::p_init) and a bunch of other stuff that doesn't get used.
// Someone should put that class out of our misery.
SchemaColumn* col = outputSchema[i];
AbstractExpression * expr = col->getExpression();
columnTypes.push_back(expr->getValueType());
columnSizes.push_back(expr->getValueSize());
columnInBytes.push_back(expr->getInBytes());
}
TupleSchema* schema =
TupleSchema::createTupleSchema(columnTypes, columnSizes,
columnAllowNull, columnInBytes);
return schema;
