	`__del__(self)`
	`authorize(self, request, length)` After the server has accepted a request it can authorize the request if it wants the transfer to proceed
	`deny(self, request, reason, message)`
	`get_base_url(self)` Calls the listener's get base url function
	`register_accept(self, attr, callback, arg)` Has the server accept an incoming client request This function should be called after the callback for register_listen has been called back Does not block
	`register_listen(self, callback, arg)` Has the server listen for incoming client request
Inherited from TransData
	`free_callback(self, cbHandle)` Free a callback.
	`receive_bytes(self, request, buffer, wait_for_amount, callback, arg)` Return a SWIG'ized pointer to the callback handle is returned.
	`send_bytes(self, request, buffer, eof, callback, arg)` After authorizing a request the server calls send bytes which sends the data in the buffer object

Method Details

init(self, scheme)
(Constructor)

*Args*

*scheme* is a string of the protocol that will be used

Overrides:: pyGlobus.gassTransfer.TransData.__init__

authorize(self, request, length=0)

After the server has accepted a request it can authorize the request if it wants the transfer to proceed

Parameters:: request - a server side request returned from the register_accept call; length - the number of bytes that the request is authorized to make the default 0, will use GLOBUS_GASS_TRANSFER_LENGTH_UNKNOWN

Returns:: returns a TransRequest object which will be needed for a send_bytes call

Raises:: TransferServerException - A TransferServerException if the request cannnot be authorized

get_base_url(self)

Calls the listener's get base url function

register_accept(self, attr, callback, arg)

Has the server accept an incoming client request This function should be called after the callback for register_listen has been called back Does not block

Parameters:: attr - a ListenerAttr object; callback - the function that will be called as soon a a client request is registered; arg - a user supplied arguement to the callback function

Returns:: A TransRequest object is returned the request object is a server_side request

Raises:: GassTransferServerException - A GassTransferServerException is Raised if the server is unable to accept this client request

register_listen(self, callback, arg)

Has the server listen for incoming client request

Does not block

Parameters:: callback - the function that will be called as soon a a client request is registered; arg - a user supplied arguement to the callback function

Returns:: A SWIG'ized pointer to the callback handle is returned. After the callback completes, this may be free'd with the free_callback method, or it will be free'd when the instance is destroyed.

Raises:: GassTransferServerException - A GassTransferServerException is Raised if the server is unable to listen for client requests
