Detailed Description

Socket poll operation object returned by Socket polling methods.

This class implements the polling logic for Sockets and the state machine behind it

private members:

• Socket sock: the Socket being polled
• string goal: the goal of the poll operation

Since

Qore 1.12

Member Function Documentation

constructor()

Qore::SocketPollOperation::constructor	(	Socket	socket,
		string	goal,
		*hash< auto >	opts
	)

Creates the object with the given goal.

Parameters

socket	the Socket object to poll
goal	the type of goal; currently one of: connect connect-ssl
opts	required keys depend on goal for goal_type connect and connect-ssl: url (string): the URL to connect to

Exceptions

INVALID-GOAL

thrown if the goal is invalid

continuePoll()

*hash<SocketPollInfo> Qore::SocketPollOperation::continuePoll ( )

virtual

Returns a socket poll hash if polling should continue or NOTHING if complete.

Returns

NOTHING if there is no more to poll and the poll operation was successful (i.e. the goal was reached), otherwise this method must return a new socket poll hash to continue the polling operation with another operation, after which this method will be called again if a matching event is received for the socket. If a socket poll hash is returned, then the internal state is also updated.

Implements Qore::AbstractPollOperation.
