Detailed Description

template<class T>
class SumAttribute< T >

Computes a summary of the specified property.

---

Constructor & Destructor Documentation

template<class T> SumAttribute< T >::SumAttribute (  const PacketAttribute &  attrib  )  throw ( InvalidDatatypeException )

Create a new SumAttribute Parameters: incHdr  include the bytes of the header in the total (default true) Exceptions: InvalidDatatypeException  if the attribute is not of the correct type

---

Member Function Documentation

template<class T> void SumAttribute< T >::compute (  void   )  throw ( ArithmeticOverflowException ) [virtual]

Compute the value of the attribute. Used to update an offline attribute. Reimplemented from Attribute.

template<class T> T SumAttribute< T >::getValue (  void   )  const throw ( ArithmeticOverflowException ) [virtual]

get the value of the attribute Exceptions: ArithmeticOverflowException  is thrown if the value is too large Reimplemented from ScalarAttribute< T >.

void FilteredPacketListener::handlePacket (  TraceIterator &  newPkt  )  [virtual, inherited]

checks the packet against the filter and calls handlePassedPacket if it passes or if the filter is NULL Implements PacketListener.

template<class T> void SumAttribute< T >::handlePassedPacket (  TraceIterator &  packet  )  throw ( ArithmeticOverflowException ) [virtual]

Notify the attribute of a new packet to be included in the computation. For an online attribute, update the attribute. For an offline attribute, set the dirty bit. (default) Reimplemented from Attribute.

template<class T> void SumAttribute< T >::linkToAggregate (  Aggregate &  parent  )  [virtual]

Notify the Attribute that it is being linked to a particular aggregate. Parameters: parent  New parent aggregate - will supplant any previous parent Note: If an Attribute subclass is only intended for use with a particular subtype of aggregate, override this method and add type checking. e.g.: Trace *trace = dynamic_cast<Trace*>(parent); if( NULL != trace ) {...} else throw InvalidAggregateException(...); Reimplemented from Attribute.

template<class T> void SumAttribute< T >::reset (  void   )  [virtual]

Reset the value of the attribute. Exceptions: NotResettableException  if the Attribute cannot be properly reset, e.g. if it is a wrapper for a subattribute. Reimplemented from Attribute.
