Parameters:: dyad -; state -

evaluate

                     State state)

evaluate2

public void evaluate2(Monad monad,
                      State state)

doMonadicTilde

protected void doMonadicTilde(Monad monad,

                               boolean isPlusPlus)

NOTE that at this point this only works for single variables -- you can't apply this to a stem.

Parameters:: monad -; state -; isPlusPlus -

doMonadNot

protected void doMonadNot(Monad monad,
                          State state)

doUnaryPlusMinus
```
protected void doUnaryPlusMinus(Monad monad,
                                State state,
                                Long sign)
```
This will evaluate the expression and take its opposite. This is because the parser does not differentiate between -3^4 and (-3)^4, turing the first of each into a single monad. It works right if there are parentheses, but this is possible a thronier issue to fix than we want now. Best to ket it do this since algebraic operations work as expected.

Parameters:

monad -

state -

sign -

doMonadPlus

protected void doMonadPlus(Monad monad,
                           State state)

doMonadMinus

protected void doMonadMinus(Monad monad,
                            State state)

evaluate

public void evaluate(Nilad nilad,
                     State state)

evaluate
```
public boolean evaluate(Polyad polyad,
                        State state)
```
Description copied from class: AbstractEvaluator

Decides if a Polyad is evaluated by this evaluator and if not, returns false, if so, it evaluates it and returns true. This function actually just dispatches it to AbstractEvaluator.dispatch(Polyad, State) where the work is done and manages putting better trace information in if there is a failure.

Overrides:

evaluate in class AbstractEvaluator

Returns:

dispatch
```
public boolean dispatch(Polyad polyad,
                        State state)
```
Description copied from class: AbstractEvaluator

Does the actual evaluation of the Polyad.

Specified by:

dispatch in class AbstractEvaluator

Returns:

getArgCount

public int[] getArgCount(Monad monad)

getArgCount

public int[] getArgCount(Dyad dyad)
