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
namethe name of the connection
descconnection description
urlconnection URL
monitormonitoring flag
optsconnection options
n_urlhbroken 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
namethe name of the connection
descriptionconnection description
urlconnection URL (potentially with password info)
attributesvarious attributes. See below
optionsconnection 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
connectif True, then the target directory is checked for existence and if it's writable, if either check fails, an exception is thrown
rtoptsthis 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
