## Member Function Documentation

bool Glom::UsesRelationship::get_has_related_relationship_name | ( | ) | const

bool Glom::UsesRelationship::get_has_relationship_name | ( | ) | const

sharedptr<const Relationship> Glom::UsesRelationship::get_related_relationship | ( | ) | const

Return the related relationship used by this item, if any, or a null sharedptr.

See also get_has_related_relationship_name() which can prevent the need for your own null sharedptr check.

Glib::ustring Glom::UsesRelationship::get_related_relationship_name | ( | ) | const

Convenience function, equivalent to get_relationship()->get_name().

sharedptr<const Relationship> Glom::UsesRelationship::get_relationship | ( | ) | const

Return the relationship used by this item, if any, or a null sharedptr.

See also get_has_relationship_name() which can prevent the need for your own null sharedptr check.

Glib::ustring Glom::UsesRelationship::get_relationship_name | ( | ) | const

Convenience function, equivalent to get_relationship()->get_name().

Glib::ustring Glom::UsesRelationship::get_relationship_name_used | ( | ) | const

Get the name of the related relationship used, if any, or the relationship if there is no related relationship, or an empty string if neither are used by this item.

bool Glom::UsesRelationship::get_relationship_used_allows_edit | ( | ) | const

Discover whether the relationship used allows the user to edit values in its to table.

Glib::ustring Glom::UsesRelationship::get_sql_join_alias_name | ( | ) | const

Get a name to use as an alias in SQL statements.

This will always be the same string for items that have the same definition.

Glib::ustring Glom::UsesRelationship::get_sql_table_or_join_alias_name | ( | const Glib::ustring & | parent_table ) | const

Get the item's alias name, if it uses a relationship, or just get its table name.

Parameters:

  parent_table | The table to which the item (or its relatinoships) belong.

Glib::ustring Glom::UsesRelationship::get_table_used | ( | const Glib::ustring & | parent_table ) | const

Returns either the parent_table, related to table, or doubly-related to-table.

Glib::ustring Glom::UsesRelationship::get_title_singular_used | ( | const Glib::ustring & | parent_table_title ) | const

Get the singular title of the relationship that is actually used, falling back to the regular (plural) title, and then to the relationship's name.

Parameters:

  parent_table_title | The title of table to which the item (or its relatinoships) belong.

Glib::ustring Glom::UsesRelationship::get_title_used | ( | const Glib::ustring & | parent_table_title ) | const

Get the title of the relationship that is actually used, falling back to the relationship's name.

Parameters:

  parent_table_title | The title of table to which the item (or its relatinoships) belong.
