Field Detail

fbDataCopyMode

protected Bool_t fbDataCopyMode

switches buildmbs event mode: if true, data buffer is copied
to own buffer of subevent. If false (default), mbs subevent uses
reference to external data buffer of eventapi.

protected Bool_t fbIsOpen

public const static const UInt_t fguEVHEBYCHAR

ratio sizeof(s_evhe) by sizeof(char).

public const static const UInt_t fguLONGBYCHAR

ratio sizeof(long) by sizeof(char).

public const static const UInt_t fguLONGBYSHORT

ratio sizeof(long) by sizeof(short).

public const static const UInt_t fguSHORTBYCHAR

ratio sizeof(short) by sizeof(char).

private Int_t fiMode

Mode of operation

protected Int_t fiTimeout

Timeout in seconds for mbs getevent. If -1, no timeout (default)

protected UInt_t fuEventCounter

Current event index counter

protected UInt_t fuEventInterval

Number of events to skip from file in between two read events

protected UInt_t fuStartEvent

Index of first event to process.

protected UInt_t fuStopEvent

Index of last event to process.

protected s_bufhe* fxBuffer

Points to the current gsi buffer structure filled by the event source.

protected s_ve10_1* fxEvent

protected s_filhe* fxInfoHeader

Reference to header info delivered by source.

protected s_evt_channel fxInputChannel

Event channel structure used by event source.

protected TGo4MbsSourcePrintPar fxPrEventPar

This structure keeps parameters for printevent mode

public TGo4MbsSource()

default for streamer

public TGo4MbsSource(const char * name, Int_t mode)

public virtual synchronized ~TGo4MbsSource()

public void BuildMbsEvent(TGo4MbsEvent* target)

This methods actually fills the target event class which is passed as pointer. Uses the latest event which is referenced
by fxEvent or fxBuffer. Does _not_ fetch a new event
from source, therefore one source event may be used
to fill several TGo4MbsEvent classes. To get a new
event call NextEvent() before this method.

public virtual Int_t Close()

Close the file or connection.

public virtual s_bufhe* GetBufferHeader()

User access to current event buffer header.

public s_filhe* GetInfoHeader()

User access to info header. May contain additional run information

public virtual Int_t NextEvent()

Requests the next event from mbs source. Returns event status value.

public virtual Int_t Open()

Open the file or connection.

public void SetDataCopyMode(Bool_t on)

public void SetEventInterval(UInt_t skipinterval)

public void SetPrintEvent(Int_t num, Int_t sid, Int_t longw, Int_t hexw, Int_t dataw)

Set mbs source into printout (verbose) mode for the next num
events. Subevent id sid may be specifiec (-1 is all subevents).
Parameters longw, hexw, dataw switch output data formats.
See MbsAPI function f_evt_type().

public void SetStartEvent(UInt_t firstindex)

Define the Start index for the NextEvent

public void SetStopEvent(UInt_t lastindex)

public void SetTimeout(Int_t time)
