Method Detail

openSocket

protected void openSocket()
                   throws IOException

Throws:

IOException

setTmSink

public void setTmSink(TmSink tmSink)

Description copied from interface: TmPacketDataLink

sets the tm processor that should get all the tm packets

Specified by:

setTmSink in interface TmPacketDataLink

Overrides:

setTmSink in class AbstractTmDataLink

run

public void run()

Overrides:

run in class AbstractTmDataLink

getNextPacket

public PacketWithTime getNextPacket()

getLinkStatus

public Link.Status getLinkStatus()

Description copied from interface: Link

Returns the current link status.

triggerShutdown

public void triggerShutdown()

Overrides:

triggerShutdown in class com.google.common.util.concurrent.AbstractExecutionThreadService

disable

public void disable()

Description copied from interface: Link

Disable any data I/O through this link. Any connection to a server is closed. Can be reenabled using the enable method. Note that this method can be called before starting the service if it's configured as such in the configuration file

enable

public void enable()

Description copied from interface: Link

Reenable the data transit if disabled by the disable() method.

isDisabled

public boolean isDisabled()

getDetailedStatus

public String getDetailedStatus()

Returns:

more detailed status information

getDataCount

public long getDataCount()

setupSysVariables

protected void setupSysVariables()

getSystemParameters

public Collection<ParameterValue> getSystemParameters()

Description copied from interface: SystemParametersProducer

return the next bunch of parameter values. The values must contain a reference to a Parameter (i.e. parameter definition) and that Parameter does not need to be coming from the XtceDB - the provider can just make it up on the fly.

Specified by:

getSystemParameters in interface SystemParametersProducer

Overrides:

getSystemParameters in class AbstractTmDataLink
