import_from_model

Description:

public bool import_from_model (DataModel from, bool overwrite, HashTable<int,int>? cols_trans) throws Error

Copy the contents of the from data model to the this data model.

The copy stops as soon as an error orrurs.

The cols_trans is a hash table for which keys are this columns numbers and the values are the corresponding column numbers in the from data model. To set the values of a column in this to NULL, create an entry in the hash table with a negative value. For example: <programlisting><![CDATA[GHashTable *hash; gint *ptr; hash = g_hash_table_new_full (g_int_hash, g_int_equal, g_free, NULL); ptr = g_new (gint, 1); *ptr = 2; g_hash_table_insert ( hash, ptr, GINT_TO_POINTER (3)); gda_data_model_import_from_model (...); g_hash_table_free (hash); ]]></programlisting>

Upon errors FALSE will be returned and throws will be assigned a Error from the DataModelError domain.

Parameters:

this	the destination DataModel
from	the source DataModel
overwrite	TRUE if this is completely overwritten by `from`'s data, and FALSE if `from`'s data is appended to this
cols_trans	a GenericSet for columns translating, or null

Returns:

TRUE if no error occurred.
