Variables:

PThread::RWLockC stateAccess;
IOSerialC sio;: Serial port.
BooleanT monitorRunning;: Set to TRUE when monitor started.
IntT replyCount;
HashARC level;: State of switches.
PThread::MutexC cmdAccess;
PThread::SemaphoreC sendSema;

Methods:

SwitchLeitchBodyC(const StringC & port): Open connection via port.
SwitchLeitchBodyC(const StdIO::ConfigFileC & conf): Open connection via port.
StringC SwitchID(const StringC & matrixId): Get identifier for the switch.
StringC SwitchMedia(const StringC & matrixId): Get media type for switch.
e.g. Video-SDI,Video-Component,Audio-Analog ....
DListC<StringC> ListResources(const StringC & matrixId,SwitchResourceT rtype): List sources available.
DListC<ConnectionC> ListConnections(const StringC & matrixId): List sources available.
BooleanT Connect(const StringC & matrixId,const StringC & src,const StringC & dest,const StringC & attr = StringC("")): Connect source to destination.
BooleanT Connect(const DListC<ConnectionC> & cons): Make a set of connections.
If any of the connections aren't possible, the whole command fails and no changes are made.
BooleanT Disconnect(const StringC & matrixId,const StringC & src,const StringC & dest,const StringC & attr = StringC("")): Connect source to destination.
BooleanT IsConnected(const StringC & matrixId,const StringC & src,const StringC & dest): Test if connection is present.
void ProbeSwitch()
BooleanT Int2hex(int n,StringC & buff): Convert number to hex.
BooleanT Hex2int(const StringC & str,IntT & val): Convert hex to a number.
IntT SHex2int(const StringC & str): Convert hex to a number.
StringC SInt2hex(int v): Convert hex to a number.
void Init(): Initalise.
void Monitor(): Monitor routine for switch.
This monitors the switch for status changes.
void updateAdd(const StringC & lvl,const StringC & src,const StringC & dest): Add connection.
This will also issue appropriate signals.
void updateDel(const StringC & lvl,const StringC & src,const StringC & dest): Del connection.
This will also issue appropriate signals.
void updateLevel(const StringC & lvl,int nsrc,int ndest,BooleanT ok): Update information about a level.
void SendCmd(const StringC & str): Send a command to the switch.
BooleanT RecvData(StringC & buff): Read from data from serial port.

#include "amma/Studio/SwitchDriver.hh"

BooleanT Save(BinOStreamC & os) const: Save model to a stream.
StringC SwitchID(const StringC & matrixId): Get identifier for the switch.
StringC SwitchMedia(const StringC & matrixId): Get media type for switch.
e.g. Video-SDI,Video-Component,Audio-Analog ....
DListC<StringC> ListResources(const StringC & matrixId,SwitchResourceT rtype): List sources available.
DListC<ConnectionC> ListConnections(const StringC & matrixId): List sources available.
BooleanT Connect(const StringC & matrixId,const StringC & src,const StringC & dest,const StringC & attr = StringC("")): Connect source to destination.
BooleanT Disconnect(const StringC & matrixId,const StringC & src,const StringC & dest,const StringC & attr = StringC("")): Connect source to destination.
BooleanT Disconnect(const ConnectionC & con): Connect source to destination.
BooleanT Connect(const DListC<ConnectionC> & cons): Make a set of connections.
If any of the connections aren't possible, the whole command fails and no changes are made.
BooleanT IsConnected(const StringC & matrixId,const StringC & src,const StringC & dest): Test if connection is present.
BooleanT IsConnected(const ConnectionC & con): Test if connection is present.
Signal1C<ConnectionC> & SigConnect(): Connection changed signal.

#include "amma/BRefCntV.hh"

BodyRefCounterVC & Copy() const: Creat a copy of this object.
BooleanT operator==(const BodyRefCounterVC & oth) const: Compair identitys.
BooleanT operator!=(const BodyRefCounterVC & oth) const: Compair identitys.
BooleanT Save(ostream & out) const: Save to ostream.

#include "amma/BRefCnt.hh"

void AddReference(): Another reference to the object has been created.
void RemoveReference(): One reference to the object was deleted.
Locking scheme -------------- The object is possible to lock (to make constant). The scheme assumes that the object is created, it can be locked, after that it can only be destroyed. The locked object cannot be unlocked. This locking scheme is very useful during debugging, using assert() function, when it is necassary to check that object is treated as constant and the constancy is not violated by any casting or passing through the copy constructor of shared objects.
void SetConst(void) const: This locks the object.
Often objects you wish to lock are already const.
void SetConst(void): This locks the object.
BooleanT IsConst(void) const: Returns TRUE if the object is locked, ie. it is assumed to be constant.
BooleanT IsNotConst(void) const: Returns TRUE if the object is unlocked.
ie. there is no special information if the object is constant or not. Counter state information -------------------------
BooleanT ToBeDeleted() const: Returns TRUE if there is only one reference to the object and the whole object or its reference counting part can be deleted.
BooleanT ToBeDeletedRemoveIgnoreNoRemove(): Decrement refrence by 1 return true if this leaves no refrences to the object.
BooleanT ToBeDeletedRemove(): Decrement refrence by 1 return true if this leaves no refrences to the object. This also checks the NoRemove flag.
BooleanT BodyMightBeDeleted() const: Returns TRUE if the reference counted part of the object can be deleted, ie. flag NOREMOVE is false .
BooleanT IsCountZero() const: Are there any refrences left ?
BooleanT BRCPtrCanDeleteObject() const: Used by BRRCPtrC to establish if an object has ZERO refrences and can be deleted.
IntT Count() const: Returns the current state of the counter, ie. how many references to this object exist.
const BodyRefCounterC & operator=(const BodyRefCounterC & b): It has not meaning to assign object 'b' to this object because it would destroy a history of the object which is counted. So this is a dummy function.
BooleanT IsValidObject() const: Test if object is valid.
When amma check is disabled this always returns true.
BooleanT UserBitTest(IntT x) const: Test user flag.
void UserBitSet(IntT x,BooleanT setit = TRUE): Test user flag.
void UserBitZero(IntT x): Set bit to zero.
void ReportBRCError(char * Msg): Report error, used in BRCPtrC.
UIntT Hash() const: Hash on address of object.
void SetUndeletable(): Make object undeletable.
Usefull to prevent recursive deleting in graph structures. Only hackers need this function.
void ReportInvalidObject(char * Msg = 0) const: Tell user about validation failure.

#include "amma/RefCBase.hh"

LabelT Label() const: Returns the label of this reference counter.
The member function is useful mainly to recognize objects during debugging. The value of the label is uniquely defined pointer.
