Member Function Documentation

constructor() [1/2]

deprecated ConnectionProvider::InvalidConnection::constructor	(	string	n_name,
		string	n_desc,
		string	n_url,
		*hash	n_opts,
		string	n_error,
		hash	urlh
	)

DEPRECATED: creates the invalid connection object.

Deprecated:

since Qore 0.9

constructor() [2/2]

ConnectionProvider::InvalidConnection::constructor	(	string	name,
		string	description,
		string	url,
		hash	attributes = {},
		hash	options = {}
	)

creates the invalid connection object

Parameters

name	the name of the connection
description	connection description
url	connection URL (potentially with password info)
attributes	various attributes. See below
options	connection options

See AbstractConnection::constructor() for attributes and options reference.

Additional Attributes

• error a custom error string

parseUrl()

hash ConnectionProvider::InvalidConnection::parseUrl ( string  url )

private

Parse the URL to a hash.

Parameters

url	a string with url

Returns

hash with url - string as url

The reason for this is to avoid a unwanted Qore::parse_url() call in connections with custom parseUrl() implementation.
