API Reference
 | 
						|
=============
 | 
						|
 | 
						|
The UDAF API consists of a set of classes and structures used to implement a MariaDB Columnstore UDAF and/or UDAnF.
 | 
						|
 | 
						|
The classes and structures are:
 | 
						|
 | 
						|
* class UDAFMap
 | 
						|
* struct UserData
 | 
						|
* class mcsv1Context
 | 
						|
* struct ColumnDatum
 | 
						|
* class mcsv1_UDAF
 | 
						|
 | 
						|
The following Columnstore classes are also used:
 | 
						|
 | 
						|
* execplan::CalpontSystemCatalog::ColDataType
 | 
						|
* messageqcpp::ByteStream
 | 
						|
 | 
						|
We also define COL_TYPES as a vector of pairs containing the column name and it's type.
