Abstract Value Members

abstract def astID: Int

Each type of node is assigned a different id to make it easily possible to do a switch over all nodes.

abstract def cTpe: ComputationalType

The computational type of the underlying value.
The computational type of the underlying value. I.e., an approximation of the type of the underlying value. It is the best type information directly available. The precision of the type information depends on the number of pre-/post-processing steps that are done.
abstract def isSideEffectFree: Boolean

true if the expression is GUARANTEED to have no externally observable effect if it is not executed.
true if the expression is GUARANTEED to have no externally observable effect if it is not executed. Sideeffect free instructions can be removed if the result of the evaluation of the expression is not used. For those expressions, which may result in an exception it has to be guaranteed that the exception is NEVER thrown. For example, a div instruction is sideeffect free if it is (statically) known that the divisor is always not equal to zero; otherwise, even if the result value is not used, the expression is not (potentially) side effect free.
returns
true if the expression is GUARENTEED to have no side effect other than wasting some CPU cycles if it is not executed.
