## Detailed Description

Driver is a module specialized for implementing channel drivers

void* getObject (const String& name) | ### getObject

[const virtual]

Get a pointer to a derived class given that class name

Parameters:

name | Name of the class we are asking for

Returns: Pointer to the requested class or NULL if this object doesn't implement it

Reimplemented from Module.

inline const String& prefix () | ### prefix

[const]

Retrieve the prefix that is used as base for all channels

Returns: The driver's prefix

inline bool varchan () | ### varchan

[const]

Check if this driver is for dynamic (variable number) channels

Returns: True if the channels are dynamic, false for fixed

inline ObjList& channels () | ### channels

Get the list of channels of this driver

Returns: A reference to the channel list

Channel* find (const String& id) | ### find

[const virtual]

Find a channel by id

Parameters:

id | Unique identifier of the channel to find

Returns: Pointer to the channel or NULL if not found

bool isBusy () | ### isBusy

[const virtual]

Check if the driver is actively used.

Returns: True if the driver is in use, false if should be ok to restart

Reimplemented from Plugin.

void dropAll (Message &msg) | ### dropAll

[virtual]

Drop all current channels

Parameters:

msg | Notification message

bool canAccept (bool routers = true) | ### canAccept

[virtual]

Check if new connections can be accepted

Parameters:

routers | Set to true to check routing threads for incoming connections

Returns: True if at least one new connection can be accepted, false if not

bool canRoute () | ### canRoute

[virtual]

Check if new incoming connections can be routed

Returns: True if at least one new connection can be routed, false if not

unsigned int nextid () | ### nextid

Get the next unique numeric id from a sequence

Returns: A driver unique number that increments by 1 at each call

inline unsigned int lastid () | ### lastid

[const]

Get the current (last used) unique numeric id from a sequence

Returns: The driver unique number

inline int timeout () | ### timeout

[const]

Get the default driver timeout

Returns: Timeout value in milliseconds

inline int routing () | ### routing

[const]

Get the number of calls currently in the routing stage

Returns: Number of router threads currently running

inline int routed () | ### routed

[const]

Get the number of calls successfully routed

Returns: Number of calls that have gone past the routing stage

inline int total () | ### total

[const]

Get the total number of calls ever created

Returns: Number of channels ever created for this driver

inline int chanCount () | ### chanCount

[const]

Get the number of running channels

Returns: Number of channels running at this time

inline int maxChans () | ### maxChans

[const]

Get the maximum number of running channels for this driver

Returns: Maximum number of calls to run simultaneously, zero to accept all

Driver (const char* name, const char* type = 0) | ### Driver

[protected]

Constructor

Parameters:

name | Plugin name of this driver
type | Type of the driver: "fixchans", "varchans", etc.

void initialize () | ### initialize

[protected virtual]

This method is called to initialize the loaded module

Reimplemented from Module.

void setup (const char* prefix = 0, bool minimal = false) | ### setup

[protected]

Install standard message relays and set up the prefix

Parameters:

prefix | Prefix to use with channels of this driver
minimal | Install just a minimal set of message relays

Reimplemented from Module.

bool received (Message &msg, int id) | ### received

[protected virtual]

Message receiver handler

Parameters:

msg | The received message
id | The identifier with which the relay was created

Returns: True to stop processing, false to try other handlers

Reimplemented from Module.

void genUpdate (Message& msg) | ### genUpdate

[protected virtual]

Opportunity to modify the update message

Parameters:

msg | Status update message

Reimplemented from Module.

bool hasLine (const String& line) | ### hasLine

[protected const virtual]

Check if driver owns a client line (registered to an external server)

Parameters:

line | Name of the line to check

Returns: True if this driver owns line with the specified name

bool msgRoute (Message& msg) | ### msgRoute

[protected virtual]

Routing message handler. The default implementation routes to this driver if it owns a line named in the "account" or "line" parameter.

Parameters:

msg | Call routing message

Returns: True to stop processing the message, false to try other handlers

Reimplemented from Module.

bool msgExecute (Message& msg, String& dest) | ### msgExecute

[protected pure virtual]

Create an outgoing calling channel

Parameters:

msg | Call execute message
dest | Destination of the new call

Returns: True if outgoing call was created

bool commandComplete (Message& msg, const String& partLine, const String& partWord) | ### commandComplete

[protected virtual]

Complete a command line

Parameters:

msg | Message to return completion into
partLine | Partial line to complete, excluding the last word
partWord | Partial word to complete

Returns: True to stop processing the message, false to try other handlers

Reimplemented from Module.

void statusModule (String& str) | ### statusModule

[protected virtual]

Build the module identification part of the status answer

Parameters:

str | String variable to fill up

Reimplemented from Module.

void statusParams (String& str) | ### statusParams

[protected virtual]

Build the parameter reporting part of the status answer

Parameters:

str | String variable to fill up

Reimplemented from Module.

void statusDetail (String& str) | ### statusDetail

[protected virtual]

Build the channel list part of the status answer

Parameters:

str | String variable to fill up

Reimplemented from Module.

bool setDebug (Message& msg, const String& target) | ### setDebug

[protected virtual]
