getFunctionNames

evaluate

public boolean evaluate(String alias,
                        Polyad polyad,
                        State state)

Overrides:

evaluate in class AbstractEvaluator

doIsFunction

protected void doIsFunction(Polyad polyad,
                            State state)

checkIsFunction

protected Boolean checkIsFunction(String fName,
                                  int argCount,
                                  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:

isFDef

protected boolean isFDef(Statement statement)

doJavaFunction

protected void doJavaFunction(Polyad polyad,
                              State state,
                              FR_WithState frs)
                       throws Throwable

Throws:

Throwable

tryScript

protected boolean tryScript(Polyad polyad,
                            State state)

figureOutEvaluation

protected void figureOutEvaluation(Polyad polyad,
                                   State state,
                                   boolean checkForDuplicates)
                            throws Throwable

Throws:

Throwable

doFunctionEvaluation

protected void doFunctionEvaluation(Polyad polyad,
                                    State state,
                                    FR_WithState frs)
                             throws Throwable

Throws:

Throwable

resolveArguments

protected ArrayList<XThing> resolveArguments(FunctionRecordInterface functionRecord,
                                             Polyad polyad,
                                             State state,
                                             State localState)

This will take the function record and polyad and find the arguments that are requested in the function record vs. what's in the polyad and stash them in the correct state objects.

Parameters:

functionRecord -

polyad -

state -

localState -

isFunctionReference

protected boolean isFunctionReference(String name)

dereferenceFunctionName

protected String[] dereferenceFunctionName(String name)
