RVInstance PLearn::RandomVar::operator== (  const Var &  v  )  const

RandomVar PLearn::RandomVar::operator[] (  RandomVar  index  )

extract from joint or element of vector Definition at line 95 of file RandomVar.cc.

ConditionalExpression PLearn::RandomVar::operator| (  RVInstanceArray  rhs  )  const

This operator represents expressions of the form Y|(X==x && Z==z). Definition at line 152 of file RandomVar.cc.

ConditionalExpression PLearn::RandomVar::operator| (  RVArray  rhs  )  const

This operator represents expressions of the form Y|(X&Z). It is almost the same as & (i.e. it also builds a RVArray), but it allows us to know that the LHS of the | will always be the first element of the array, so if the user types ((Y&Z)|(X&U)) the result will be a 3-element array, because the first two-element array created by (Y&Z) is coerced into a JointRV, which will be the first element of the result.
