Detailed Description

class for FTP connections; returns Qore::FtpClient objects

supports the following runtime options in getImpl():

  • "path": overrides the path component in the URL at runtime
  • "path_add": appends the given string to the path component of the URL at runtime

Member Function Documentation

◆ constructor()

ConnectionProvider::FtpConnection::constructor ( string  name,
string  description,
string  url,
hash< auto >  attributes = {},
hash< auto >  options = {} 
)

creates the FtpConnection 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.

Exceptions
CONNECTION-OPTION-ERRORmissing or invalid connection option

◆ getDataProvider()

DataProvider::AbstractDataProvider ConnectionProvider::FtpConnection::getDataProvider ( )

returns an FtpClientDataProvider object for this connection

Returns
an FtpClientDataProvider object for this connection
See also
hasDataProvider()

◆ getImpl()

FtpClient ConnectionProvider::FtpConnection::getImpl ( bool  connect = True,
*hash< auto >  rtopts 
)
privatevirtual

returns an Qore::FtpClient object

Parameters
connectif True then a connection is made any if there is any path in the URL a CWD operation is performed to change to the target directory
rtoptsthis connection type does not accept any runtime option, so this parameter is ignored

Implements ConnectionProvider::AbstractConnection.

◆ getRuntimeOptions()

*hash< auto > ConnectionProvider::FtpConnection::getRuntimeOptions ( )

returns runtime options

return a hash with the following keys reflecting support for the corresponding runtime options in getImpl():

  • "path": overrides the path component in the URL at runtime
  • "path_add": appends the given string to the path component of the URL at runtime

◆ hasDataProvider()

bool ConnectionProvider::FtpConnection::hasDataProvider ( )

returns True, as the connection returns a data provider with the getDataProvider() method

Returns
True, as the connection returns a data provider with the getDataProvider() method
