Etymology

VACEngine stands for Virtual Array Column Engine, i.e. a class handling a virtual table column containing array values.

Synopsis

VACEngine is a base virtual column engine to handle a column with an arbitrary type. Data of columns with standard data types can directly be stored in a Table using a storage manager, but data of column with non-standard types have to be stored in another way. The way to do this is to split the object with the non-standard type into its individual elements, which are subsequently put into the appropriate columns.

A virtual column engine has to be implemented for each non-standard data type, which has to be stored in a table. This engine has to get and put the individual parts the object. VACEngine is the base class for such engines, so the actual engine quite simple to implement. The example shows the implementation of an engine AVACEngine handling a data type A.

In principle the name of the engine class is free, but it is strongly recommended to use the name <dataTypeId>VACEngine, where VAC stands for Virtual Array Column (e.g. AVACEngine for class A). In this way the default data manager name supplied by the class and by class ArrayColumnDesc can be used.

Example

This example shows the implementation of an engine class AVACEngine, which stores the data of a class A. The data objects A are stored in a column called the source column. The user has to associate two target columns with it. The engine stores the data parts x and y in the target columns. The names of the target columns are stored as keywords in the source column. In this way the engine can reconstruct itself when the table is read back.

In the example all AVACEngine functions are shown inline, but they should be implemented out-of-line in a separate.cc file.

User code using this engine to create a new table could look like:

// Register the engine.
// This is not needed if the engine is registered as part
// of the general DataManager::registerAllCtor function.
AVACEngine::registerClass();
// Create the table description.
TableDesc td;
td.addColumn (ArrayColumnDesc<A>("source"));
td.addColumn (ArrayColumnDesc<Int>("xTarget"));
td.addColumn (ArrayColumnDesc<Int>("yTarget"));
SetupNewTable setup ("table.name", td, Table::New);
// Define the engine for column "source".
AVACEngine engine ("source", "xTarget", "yTarget");
Table tab (setup, 10);
// Put data into column "source".
ArrayColumn<A> col (tab, "source");
for (uInt i=0; i<10; i++) {
col.put (i, someA);     // writes indirectly xTarget and yTarget
}

Motivation

This class makes it easier for the user to implement the engine. It supplies several default functions.

Default constructor T();
Copy constructor T(const T&);
Assignment operator T& operator= (const T&);
comparison operator int operator== (const T&) const;
comparison operator int operator< (const T&) const;
identification static String dataTypeId(); This should return the (unique) name of the class, thus when T is templated in its turn, the name should contain the template argument name.
