Member Function Documentation

void DurationAttribute::compute (  void   )  [virtual]

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

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.

void DurationAttribute::handlePassedPacket (  TraceIterator &  packet  )  [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.

void Attribute::linkToAggregate (  Aggregate &  parent  )  [virtual, inherited]

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 in ArithmeticAttribute< lType, rType, resType >, and SumAttribute< T >.

void Attribute::reset (  void   )  throw ( NotResettableException ) [virtual, inherited]

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 in SumAttribute< T >.
