Types

type VariableResolver

type VariableResolver interface {
	VariableName() string // full name of variable
	VariableReference(*runtime.ScopeTree) *variables.PMMPVarRef
}

VariableResolver will find a variable's declaration in a scope tree, if present. It will then construct a valid variable reference for that declaration.

func ParseVariableName

func ParseVariableName(v string) (VariableResolver, error)

ParseVariableName will parse a string as a variable's name and return a VariableResolver.
