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).

The number of columns in the model.
You rarely need to use properties because there are get_ and set_ methods for almost all of them.

The number of columns in the model.
You rarely need to use properties because there are get_ and set_ methods for almost all of them.

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.
