Member Function Documentation

HashMap<String, String> edu::tum::cs::srl::bayesnets::ParentGrounder::generateParameterBindings	(	String[]	actualParameters,
		Database	db
	)			throws Exception `[inline]`

generates, for a particular binding of the main node's parameters, the complete binding of all relevant variables (which includes all variables/parameters of parents) using the functional lookups that were determined at construction time

Parameters:

	actualParameters
	db

Returns:

Exceptions:

Exception

Map<Integer, String[]> edu::tum::cs::srl::bayesnets::ParentGrounder::generateParameterSets	(	String[]	actualParameters,
		Database	db
	)			throws Exception `[inline]`

generates a grounding of all parent nodes (and the main node itself), i.e. a list of actual parameters for each node, given a vector of actual parameters for this object's main node

Parameters:

actualParameters

actual parameters of the man node for which this parameter grounding should be performed

Returns:: mapping of node indices to lists of corresponding actual parameters or null

Exceptions:

Exception

Deprecated:: this method is apparently not required; it is not referenced anywhere

void edu::tum::cs::srl::bayesnets::ParentGrounder::getCompleteGroundings	(	String[]	mainNodeParams,
		Database	db,
		HashMap< String, String >	paramBindings,
		int	idx,
		Vector< Map< Integer, String[]>>	ret
	)			throws Exception `[inline, protected]`

completes a (yet incomplete) grounding by considering all possibilities of grounding the ungrounded variables

Parameters:

	mainNodeParams
	db
	paramBindings
	idx
	ret

Exceptions:

Exception

Vector<Map<Integer, String[]> > edu::tum::cs::srl::bayesnets::ParentGrounder::getGroundings	(	String[]	actualParameters,
		Database	db
	)			throws Exception `[inline]`

generates all possible groundings of all parent nodes (and the main node itself), where a grounding is a list of actual parameters for each node, given a vector of actual parameters for this object's main node

Parameters:

actualParameters

actual parameters of the main node for which this parameter grounding should be performed

Returns:: vector of mappings of node indices to lists of corresponding actual parameters or null if there is no valid binding for the given actual parameters of the main node

Exceptions:

Exception
