apply

public abstract void apply(Interpreter r)
                    throws ContinuationException

Called when applying this procedure to a number of arguments in the Interpreter's vlr register. The code can return a value by setting the Interpreter's acc register and/or cause additional expressions to be evaluated by setting the Interpreter's nxp register.

Overrides:

apply in class Value

Parameters:

r - the Interpreter

Throws:

ContinuationException

throwPrimException

public static void throwPrimException(java.lang.String message)

throwNestedPrimException

public static void throwNestedPrimException(java.lang.String message,
                                            SchemeException e)

throwNestedPrimException

public static void throwNestedPrimException(SchemeException e)

throwArgSizeException

public static void throwArgSizeException()

error

public static void error(Interpreter r,
                         Value where,
                         NestedPrimRuntimeException parent)
                  throws ContinuationException

Throws:

ContinuationException
