Node query processing steps

Steps in processing various model queries about nodes.

Of particular interest are cases where a LHSinferred node name is provided in a nodes argument to a step where it might be parsed and evaluated in a vars2... environment. Either LHSinferred names must be ensured safe or that processing path must be prevented.

Model methods and relevance

Notes include which other major methods, or modelDef or modelDef$maps data or methods, are used.

isEndNode

• Uses expandNodeNames(...returnType = 'ids') | modelDef$maps$isEndNode_byGID.

getNodeType

• Uses modelDef$nodeName2GraphIDs

getDeclID

• Uses modelDef$nodeName2GraphIDs

getDeclInfo

getUnrolledIndicesList

getDistribution

• Uses expandNodeNames | getDeclnfo

getParamExpr

getValueExpr

isMultivariate

• Uses expandNodeNames | getDistribution

isDiscrete

isBinary

• Uses expandNodeNames | getDistribution, getParamExpr

isStoch

• Uses expandNodeNames | getNodeType

isDeterm

isTruncated

• Uses expandNodeNames | getDeclnfo

isUnivariate

• Uses expandNodeNames | getDistribution

getDimension

getVarNames

getNodeFunctions

• Uses modelDef$nodeName2GraphIDs | modelDef$graphIDs2indexedNodeInfo

getNodeNames

• Uses isDataFromGraphID(modelDef$maps$graphIDs) twice (note this is on all graphIDs)

• Uses expandNodeNames(modelDef$maps$graphID_2_nodeName[validValues],...)

expandNodeNames

• Uses modelDef$nodeName2GraphIDs | modelDef$maps$elementNames[graphID], modelDef$maps$graphID_2_nodeName[graphID]

topologicallySortNodes

• Uses expandNodeNames(..., returnType = 'ids') | expandNodeNames

getVarInfo

init_isDataEnv

resetData

setData

testDataFlags

• Uses getNodeNames() | eval(parse(...), envir = isDataEnv)

isData

• Uses modelDef$nodeName2GraphIDs | isDataFromGraphID

isDataFromGraphID

• Uses modelDef$maps$graphID_2_nodeName | eval(parse(...), envir = isDataEnv)

getDependenciesList

getDependencyPathCountOneNode

• Uses modelDef$nodeName2GraphIDs | modelDef$maps$nimbleGraph$getDependencyPathCountOneNode

getDependencies

• Uses modelDef$nodeName2GraphIDs | modelDef$maps$elementID_2_vertexID | modelDef$maps$nimbleGraph$getDependencies | modelDef$maps$types, isDataFromGraphID, modelDef$nodeName2GraphIDs(modelDef$maps$graphID_2_nodeName[depIDs], modelDef$maps$elementNames, modelDef$maps$nodeNames

Underlying modelDef methods and data used by above

nodeName2GraphIDs returns either graphIDs (nodeFunctions and RHSonly) (if nodeFunctionID == TRUE) or elementIDs.

This uses parseEval... steps so cannot take LHSinferred names.
