Detailed Description

class for filesystem connections; returns an object of type Qore::Dir; this can be used to monitor filesystem free space or to ensure a network filesystem is mounted, for example

supports the following option:

• "readonly": does not mark the connection as down if the directory is read-only; use for example if the connection should point to a read-only base directory; interface directories should normally be writable

Member Function Documentation

constructor() [1/2]

deprecated ConnectionProvider::FilesystemConnection::constructor	(	string	name,
		string	desc,
		string	url,
		bool	monitor,
		*hash	opts,
		hash	n_urlh
	)

DEPRECATED: creates the FilesystemConnection object.

Parameters

name	the name of the connection
desc	connection description
url	connection URL
monitor	monitoring flag
opts	connection options
n_urlh	broken down URL hash (as returned by Qore::parse_url())

Deprecated:

since Qore 0.9

constructor() [2/2]

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

creates the FilesystemConnection 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.

getConstructorInfoImpl()

hash<ConnectionConstructorInfo> ConnectionProvider::FilesystemConnection::getConstructorInfoImpl ( )

privatevirtual

returns a hash that can be used to contruct the object dynamically

Since

ConnectionProvider 1.1

Implements ConnectionProvider::AbstractConnection.

getImpl()

Dir ConnectionProvider::FilesystemConnection::getImpl ( bool  connect = True, *hash  rtopts  )

privatevirtual

returns a Qore::Dir object

Parameters

connect	if True, then the target directory is checked for existence and if it's writable, if either check fails, an exception is thrown
rtopts	this connection type does not accept any runtime option, so this parameter is ignored

Returns

a Qore::Dir object

Implements ConnectionProvider::AbstractConnection.

getOptions()

hash ConnectionProvider::FilesystemConnection::getOptions

(

)

gets options

Returns

returns a hash with the following supported option:

• "readonly": if True, does not mark the connection as down if the directory is read-only; use for example if the connection should point to a read-only base directory; interface directories should normally be writable (default: False)

make()

static deprecated FilesystemConnection ConnectionProvider::FilesystemConnection::make ( string  name, string  desc, string  url, bool  monitor, *hash  opts, hash  urlh  )

static

DEPRECATED: static constructor.

Deprecated:

since Qore 0.9 in favor of new constructor and Qore::Reflection
