% FINDCONNECTIONS finds a managed connection. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % % DESCRIPTION: FINDCONNECTIONS finds a managed connection. % % CALL: conns = rm.findConnections(pl); % conns = rm.findConnections('hostname'); % conns = rm.findConnections('hostname', 'database'); % conns = rm.findConnections('hostname', 'database', 'username'); % % findConneciton finds all connections which match the given input fields. % If no matching connections are found then the method returns an emtpy % array. To search for all 'hostnames' for a given 'username', enter an % empty string. For example: % % 1) Find all connections for user 'bob' % % pl = plist('username', 'bob'); % conns = rm.findConnections(pl); % % or % % conns = rm.findConnections('', '', 'bob'); % % 2) Find all connection to 'localhost' for database 'foo' % % pl = plist('hostname', 'localhost', 'database', 'foo') % conns = rm.findConnections(pl); % % or % % conns = rm.findConnections('localhost', 'foo'); % % 3) Find all connections to 'localhost' for user 'bob' % % conns = rm.findConnections('localhost', '', 'bob'); % % <a href="matlab:web(LTPDARepositoryManager.getInfo('findConnections').tohtml, '-helpbrowser')">Parameters Description</a> % % VERSION: $Id: findConnections.m,v 1.7 2011/04/08 08:56:35 hewitson Exp $ % %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% function varargout = findConnections(varargin) % Check if this is a call for parameters if utils.helper.isinfocall(varargin{:}) varargout{1} = getInfo(varargin{3}); return end import utils.const.* utils.helper.msg(msg.PROC3, 'running %s/%s', mfilename('class'), mfilename); % Get the repository manager - there should only be one!
