Detailed Description

FragmentedSectionIterator

This class acts as an adapter to a GenericSectionIterator instance, providing a sub-range iterator interface. It is used when long sections of a signal are fragmented across multiple actual signals - the user-supplied GenericSectionIterator is then adapted into a GenericSectionIterator that only returns a subset of the contained words for each signal fragment.

Member Function Documentation

const Uint32* FragmentedSectionIterator::getNextWords ( Uint32 &  sz )

inlinevirtual

getNextWords (GenericSectionIterator) Get ptr and size of next contiguous words in subrange

Implements GenericSectionIterator.

Definition at line 1041 of file TransporterFacade.cpp.

void FragmentedSectionIterator::reset ( void  )

inlinevirtual

reset (GenericSectionIterator) Reset the iterator to the start of the current sub-range Avoid calling as it could be expensive.

Implements GenericSectionIterator.

Definition at line 1027 of file TransporterFacade.cpp.

bool FragmentedSectionIterator::setRange ( Uint32  start, Uint32  len  )

inline

setRange Set the sub-range of the iterator. Must be within the bounds of the underlying iterator After the range is set, the iterator is reset() to the start of the supplied subrange
