Detailed Description

Specification for a decoding step. The factored translation model consists of Translation and Generation steps, which consult a Dictionary of phrase translations or word generations. This class implements the specification for one of these steps, both the DecodeType and a pointer to the Translation or Generation Feature

Member Function Documentation

const std::vector<FactorType>& Moses::DecodeStep::GetConflictFactors ( ) const [inline]

returns a list (possibly empty) of the (target side) factors that are produced BUT ALREADY EXIST and therefore must be checked for conflict or compatibility

References m_conflictFactors.

const DecodeGraph* Moses::DecodeStep::GetContainer ( ) const [inline]

Definition at line 111 of file DecodeStep.h.

References m_container.

References m_featuresRemaining.

Referenced by Moses::StaticData::LoadDecodeGraphsNew().

Here is the caller graph for this function:

const GenerationDictionary * Moses::DecodeStep::GetGenerationDictionaryFeature ( ) const

returns generation table feature for generation step

returns generation feature (dictionary) for generation step

Definition at line 73 of file DecodeStep.cpp.

References m_decodeFeature.

Referenced by Moses::DecodeStepGeneration::Process().

Here is the caller graph for this function:

const std::vector<FactorType>& Moses::DecodeStep::GetNewOutputFactors ( ) const [inline]

returns a list (possibly empty) of the (target side) factors that are produced in this decoding step. For example, if a previous step generated factor 1, and this step generates 1,2, then only 2 will be in the returned vector.
