= class Gda::DataModelHash
An implementation of Gda::DataModel based on a hash table.
== Object Hierarchy
* Object
* GLib::Instantiatable
* GLib::Object
* Gda::DataModel
* Gda::DataModelHash
== Class Methods
--- Gda::DataModelHash.new(n_column)
This method returns a reference to a newly created Gda::DataModelHash object.
* n_column: number of columns for rows in this data model.
* Returns: a reference to a newly created Gda::DataModelHash object.
== Instance Methods
--- clear
Frees all the rows inserted in this model.
* Returns: self.
--- get_row(rownum)
Retrieves a row from the underlying hash table.
* rownum: a row number.
* Returns: a reference to a Gda::Row or nil if the requested row is not in the hash table.
--- get_value_at(colnum, rownum)
Retrieves the value at a specified column and row.
* rownum: row number (starting from 0).
* colnum: column number (starting from 0).
* Returns: a reference to a Gda::Value object if successful, nil otherwise.
--- insert_row(rownum, row)
Inserts a row in the data model.
* rownum: the number of the row.
* row: the row to insert, as a Gda::Row object.
* Returns: self.
--- n_columns=(n_columns)
Sets the number of columns for rows inserted in this model.
* n_columns: number of columns for rows this data model should use (must be greated than or equal to 0).
* Returns: the given parameter 'n_columns'.
--- set_n_columns(n_columns)
Sets the number of columns for rows inserted in this model.
* n_columns: number of columns for rows this data model should use (must be greated than or equal to 0).
* Returns: self.
