ucam::fsttools::LoadLanguageModelTask< Data >::LoadLanguageModelTask	(	const ucam::util::RegistryPO &	rg,

inline

Public constructor. If the user wants to load several language models (e.g. –lm.load=lm1,lm2,lm3,lm4 and –lm.scale=0.25,0.25,0.25 ), the second and following instances of LoadLanguageModelTask will be created using the private constructor (see below), which has an index to the actual language model that must be loaded. For the public constructor, the index is set to 0.

Parameters

rg	ucam::util::RegistryPO object, containing user parameters.
lmload	key word to access the registry object for language models
lmscale	key word to access the registry object for language model scales.
forceone	To force the loading of only one language model (i.e. lm1 with scale 0.25).
