An implementation of DataModel based on an array.
The Gda::DataModelArray object is a data model which internally uses a GArray to index all its rows (represented as Gda::Row objects). In this data model, all the data is stored in memory, which can be a memory limitation if the number of rows is huge. This type of data model is easy to use to store some temporary data, and has a random access mode (any value can be accessed at any time without the need for an iterator).

| void Gnome::Gda::DataModelArray::set_n_columns | ( | int | cols | ) |
Sets the number of columns for rows inserted in this model.
cols must be greated than or equal to 0.
Also clears model's contents.
