Detailed Description

The client class provides a base class for classes that implement the client side of a client-server communication model.

Constructor & Destructor Documentation

◆ client()

client::client ( )

Creates an instance of the client class.

◆ ~client()

virtual client::~client ( )
virtual

Deletes this instance of the client class.

Member Function Documentation

◆ connect()

virtual int32_t client::connect ( )
virtual

This method may be implemnted by a child class to open a connection to a server, presumably specified in the "cd" parameter of the setParameters() method.

This method return an int32_t instead of a bool so child classes that have non atomic connection procedures (such as a modem) can implement return codes other than success or failure (such as abort).

This implementation just returns RESULT_SUCCESS.

Reimplemented in unixsocketclient, modemclient, and inetsocketclient.

◆ getRetryWait()

uint32_t client::getRetryWait ( )

Returns the number of seconds that connect() will wait after failing before trying again.

◆ getTimeoutMicroseconds()

int32_t client::getTimeoutMicroseconds ( )

Returns the number of microseconds (in addition to the number of seconds set by setTimeoutSeconds()) that a connect() attempt will wait before giving up.

◆ getTimeoutSeconds()

int32_t client::getTimeoutSeconds ( )

Returns the number of seconds that a connect() attempt will wait before giving up.

◆ getTries()

uint32_t client::getTries ( )

Returns the number of attemps that connect() will make before giving up.

◆ getVerboseConnectError()

const char* client::getVerboseConnectError ( )

Returns the verbose connect error.

◆ setParameters()

virtual void client::setParameters ( dictionary< const char *, const char * > *  cd)
virtual

Queries "cd" for "timeoutsec", "timeoutusec", "retrywait" and "tries" and configures this instancec to use them when connect() is called.

Reimplemented in unixsocketclient, modemclient, and inetsocketclient.

◆ setRetryWait()

void client::setRetryWait ( uint32_t  retrywait)

Sets the number of seconds that connect() will wait after failing before trying again.

Defaults to 0.

◆ setTimeoutMicroseconds()

void client::setTimeoutMicroseconds ( int32_t  timeoutusec)

Sets the number of microseconds (in addition to the number of seconds set by setTimeoutSeconds()) that a connect() attempt will wait before giving up. If set to -1 then connect() will wait forever.

Defaults to -1.

◆ setTimeoutSeconds()

void client::setTimeoutSeconds ( int32_t  timeoutsec)

Sets the number of seconds that a connect() attempt will wait before giving up. If set to -1 then connect() will wait forever.

Defaults to -1.

◆ setTries()

void client::setTries ( uint32_t  tries)

Sets the number of attemps that connect() will make before giving up. If set to 0 then connect() will attempt to connect forever. If set to 1 then connect() will only attempt to connect once.

Defaults to 1.

◆ setVerboseConnectError()

void client::setVerboseConnectError ( const char *  error)

Sets the verbose connect error. May be called by a child class to set the error that occurred during connect, if it is appropriate to give more information that would be given by error::getErrorString() or if no system-level error occurred.
