Re: [Quickfix-developers] Re: IsSetField is not available in the C# assemblies

[<sil...@tu...>]

I already found the solution. I thing that my solution is more simply.

1. Just add next methods to Quickfix::Message class

bool Message::IsSetField(QuickFix::Field& field)
{ =20

    QF_STACK_TRY

    int fieldNumber =3D field.getField();

    return m_pUnmanaged->isSetField(fieldNumber);

    QF_STACK_CATCH

}

bool Message::IsSetField(int fieldNumber)

{

     QF_STACK_TRY

    return m_pUnmanaged->isSetField(fieldNumber);

    QF_STACK_CATCH

}

2. Add next method to Quickfix::Message::Header class

bool Message::Header::IsSetField(int fieldNumber)

{

     QF_STACK_TRY

    return m_message->IsSetField(fieldNumber);

    QF_STACK_CATCH

}

3. And  add next methods to Quickfix::Message::Trailer class

bool Message::Trailer::IsSetField(int fieldNumber)

{

 QF_STACK_TRY

return m_message->IsSetField(fieldNumber);

QF_STACK_CATCH

}

4. Add to NET_FIELD_SET define which is defined in Message.h next lines:

bool IsSet##FIELD() \

{ QuickFix::FIELD* value =3D new QuickFix::FIELD(); \

int fieldnumber =3D value->getField(); \

return IsSetField(fieldnumber);}

I assume you would like to be able to do the following

//Example 1**********************************************************
MsgType mt =3D new MsgType();
if(message.getHeader().isSet(mt))
//a MsgType field exists and it's value is already in the mt variable
else
//the message does not contain a MsgType Field.  just an example
//Example =
2**************************************************************
XmlData xd =3D new XmlData()
if(message.isSet(xd))
//an XmlData field exists and it's value is already in the mt variable
else
//the message does not contain a MsgType Field.
//***********************************************************************=
*


To get the above capability, paste the following code into the public =
sections of both the Message class and the Header class in the =
src/Net/message.h file.  There is probably a better way to do this, =
which is why I never submitted it before, but it works well.  it was =
Oren's suggestion for a quick Fix (no pun intended) that he gave me =
through this message board.  Maybe he could add it to the release.
//begin copy
bool Message::isSet( StringField* f){
  try{getField(f);return true;}
  catch(Exception & e){}
  return false;
}
bool Message::isSet( BooleanField* f){
  try{getField(f);return true;}
  catch(Exception & e){}
  return false;
}
bool Message::isSet( CharField* f){
  try{getField(f);return true;}
  catch(Exception & e){}
  return false;
}
bool Message::isSet( IntField* f){
  try{getField(f);return true;}
  catch(Exception & e){}
  return false;
}
bool Message::isSet( DoubleField* f){
  try{getField(f);return true;}
  catch(Exception & e){}
  return false;
}
bool Message::isSet( UtcTimeStampField* f){
  try{getField(f);return true;}
  catch(Exception & e){}
  return false;
}
bool Message::isSet( UtcDateField* f){
  try{getField(f);return true;}
  catch(Exception & e){}
  return false;
}
bool Message::isSet( UtcTimeOnlyField* f){
  try{getField(f);return true;}
  catch(Exception & e){}
  return false;
}
//end Copy

What do you mean?
How can I resolve this problem?
