Properties:

• public Connection connection { owned get; construct; }
• public int op_type { get; construct; }
• public ServerProvider provider { owned get; construct; }
• public string spec_filename { construct; }

Static methods:

• public static Quark error_quark ()
• public static unowned string op_type_to_string (ServerOperationType type)
  Get a string version of type
• public static ServerOperation? prepare_create_database (string provider, string? db_name) throws Error
  Creates a new ServerOperation object which contains the specifications required to create a database.
• public static ServerOperation? prepare_create_table (Connection cnc, string table_name, Error error, ...)
  Add more arguments if the flag needs them:
• public static ServerOperation? prepare_drop_database (string provider, string? db_name) throws Error
  Creates a new ServerOperation object which contains the specifications required to drop a database.
• public static ServerOperation? prepare_drop_table (Connection cnc, string table_name) throws Error
  This is just a convenient function to create a ServerOperation to drop a table in an opened connection.
• public static ServerOperationType string_to_op_type (string str)
  Performs the reverse of op_type_to_string

Creation methods:

• public ServerOperation (ServerOperationType op_type, string xml_file)
  IMPORTANT NOTE: Using this funtion is not the recommended way of creating a ServerOperation object, the correct way is to use create_operation; this method is reserved for the database provider's implementation.

Methods:

• public uint add_item_to_sequence (string seq_path)
• public bool del_item_from_sequence (string item_path)
• public unowned ServerOperationNode? get_node_info (string path_format, ...)
  Get information about the node identified by path.
• public string get_node_parent (string path)
  Get the complete path to the parent of the node defined by path
• public string get_node_path_portion (string path)
  Get the last part of path
• public ServerOperationNodeType get_node_type (string path, ServerOperationNodeStatus? status)
  Convenience function to get the type of a node.
• public ServerOperationType get_op_type ()
  Get the type of operation this is for
• public string[] get_root_nodes ()
  Get an array of strings containing the paths of nodes situated at the root of this.
• public string[] get_sequence_item_names (string path)
  Fetch the contents of a sequence.
• public uint get_sequence_max_size (string path)
• public uint get_sequence_min_size (string path)
• public unowned string get_sequence_name (string path)
• public uint get_sequence_size (string path)
• public string get_sql_identifier_at_path (Connection? cnc, ServerProvider? prov, string path)
  This method is similar to get_value_at_format, but for SQL identifiers: a new string is returned instead of a Value.
• public unowned Value? get_value_at (string path)
  Get the value for the node at the path path
• public unowned Value? get_value_at_format (string path_format, ...)
  Get the value for the node at the path formed using path_format and ... (the rules are the same as for to_string)
• public bool is_valid (string? xml_file) throws Error
  Tells if all the required values in this have been defined.
• public bool load_data_from_xml (unowned Node* node) throws Error
  Loads the contents of node into this.
• public bool perform_create_database (string? provider) throws Error
  Creates a new database using the specifications in this.
• public bool perform_create_table () throws Error
  Performs a prepared ServerOperation to create a table.
• public bool perform_drop_database (string? provider) throws Error
  Destroys an existing database using the specifications in this.
• public bool perform_drop_table () throws Error
  This is just a convenient function to perform a drop a table operation.
• public virtual void seq_item_added (string seq_path, int item_index)
• public virtual void seq_item_remove (string seq_path, int item_index)
• public bool set_value_at (string? value, string path) throws Error
  Set the value for the node at the path formed using path_format and the ... ellipse (the rules are the same as for to_string).

Signals:

• public signal void sequence_item_added (string seq_path, int item_index)
  Gets emitted whenever a new sequence item (from a sequence template) has been added
• public signal void sequence_item_remove (string seq_path, int item_index)
  Gets emitted whenever a sequence item is about to be removed
