Constructor Details

UdpClientIOProcessor

public UdpClientIOProcessor(JposDevice dev,
 String addr)
                     throws jpos.JposException

Stores JposDevice and port of derived IO processors. The device will be used for logging while the port specifies the communication object.

Parameters:

dev - Device that uses the processor. Processor uses logging of device to produce logging entries

addr - Communication object, e.g. 127.0.0.1:23456 for IPv4 and [12:34:56:78:9a:bc:de:f0]:23456 for IPv6.

Throws:

jpos.JposException - If port does not specify a valid communication object

Method Details

setTarget

public String setTarget(String target)
                 throws jpos.JposException

Description copied from class: UniqueIOProcessor

Sets communication target. Depending on the IO processor type, setting communication target can be mandatory before calling method open.

Overrides:

setTarget in class UniqueIOProcessor

Parameters:

target - communication target

Returns:

target

Throws:

jpos.JposException - if target is not a valid communication target.

setParam

public void setParam(int ownport)
              throws jpos.JposException

Sets UDP specific communication parameter.

Parameters:

ownport - Own port address

Throws:

jpos.JposException - If port address < 0 or port address > 65535
