callSite

public void callSite(Args args,
                     Token caller)
              throws TokenException

Description copied from class: Site

Must be implemented by subclasses to implement the site behavior

Specified by:

callSite in class Site

Parameters:

args - list of argument values

caller - where the result should be sent

Throws:

TokenException

getMember

public java.lang.Object getMember(Token token,
                                  java.lang.Object self,
                                  java.lang.String name)
                           throws MessageNotUnderstoodException,
                                  CapabilityException,
                                  java.lang.SecurityException

Get the value of an object member (method or field). If a method and field have the same name, the method is prefered. Since in Java method values aren't first class we wrap these in a MethodProxy.

Throws:

java.lang.SecurityException

CapabilityException

MessageNotUnderstoodException

getField

public java.lang.reflect.Field getField(Token token,
                                        java.lang.String name)
                                 throws java.lang.SecurityException,
                                        java.lang.NoSuchFieldException,
                                        CapabilityException

Look up a field by name. FIXME: should distinguish between static and non-static fields?

Throws:

CapabilityException

java.lang.SecurityException

java.lang.NoSuchFieldException

getMethod

public MethodHandle getMethod(Token token,
                              java.lang.String methodName)
                       throws MessageNotUnderstoodException,
                              CapabilityException

Look up a method by name. Method handles are cached so that future lookups can go faster. FIXME: should distinguish between static and non-static methods?

Throws:

CapabilityException

MessageNotUnderstoodException
