Class UserFnCallFrame

+----UserFnCallFrame
- public class UserFnCallFrame
- extends Frame
The class `UserFnCallFrame', a subclass of Frame,
represents a frame internally as an exjava UserFnCall object - such frames
should only be used to represent user function calls in EXPRESS models.
-
UserFnCallFrame(UserFnCall, Frame)
- Constructs this frame by plugging in the given exjava UserFnCall object
(it does so by copying the reference, which is maximally efficient
but the client should not then alter the UserFnCall directly, as that
would compromise the integrity of the frame).
-
UserFnCallFrame(UserFnCall, Frame, Hashtable)
- Constructs this frame by plugging in the given exjava UserFnCall object
(it does so by copying the reference, which is maximally efficient,
but the client should not then alter the UserFnCall directly, as that
would compromise the integrity of the frame).
-
buildFrame()
- Fills in the slots for this frame from the underlying exjava UserFnCall
object.
-
buildQueuedFrames()
- Builds any UserFnCall Frames that are queued to be built (those that
were constructed before the frame class was constructed).
-
getFrameClass()
- Returns the frame class of this frame.
-
initialise(Express)
- Initialises the UserFnCallFrame class by setting the class
variable _frameClass after looking up the `user_function_call'
entity in the given EXPRESS (meta)model.
-
readClass(ObjectInput)
- Deserialises the static data members (class variables) of
UserFnCallFrame.
-
writeClass(ObjectOutput)
- Serialises the static data members (class variables) of
UserFnCallFrame.
UserFnCallFrame
public UserFnCallFrame(UserFnCall instanceData,
Frame theEntity) throws FrameAlreadyExists
- Constructs this frame by plugging in the given exjava UserFnCall object
(it does so by copying the reference, which is maximally efficient
but the client should not then alter the UserFnCall directly, as that
would compromise the integrity of the frame).
- Parameters:
- instanceData - An exjava UserFnCall object to wrap in this frame.
- theEntity - The entity which contains this function call.
- Throws: FrameAlreadyExists
- If an UserFnCall has already been
constructed for `instanceData'.
UserFnCallFrame
public UserFnCallFrame(UserFnCall instanceData,
Frame theEntity,
Hashtable moreInstanceData) throws FrameAlreadyExists
- Constructs this frame by plugging in the given exjava UserFnCall object
(it does so by copying the reference, which is maximally efficient,
but the client should not then alter the UserFnCall directly, as that
would compromise the integrity of the frame). This constructor allows
the function call frame to be tagged with extra slots, given in a
hash table.
- Parameters:
- instanceData - An exjava UserFnCall object to wrap in this frame.
- theEntity - The entity which contains this function call.
- moreInstanceData - Extra slots to tag this function call
frame with.
- Throws: FrameAlreadyExists
- If an UserFnCall has already been
constructed for `instanceData'.
initialise
public static void initialise(Express metamodel)
- Initialises the UserFnCallFrame class by setting the class
variable _frameClass after looking up the `user_function_call'
entity in the given EXPRESS (meta)model.
- Parameters:
- metamodel - An EXPRESS metamodel, which is expected to contain
the entity `user_function_call'.
buildQueuedFrames
public static void buildQueuedFrames()
- Builds any UserFnCall Frames that are queued to be built (those that
were constructed before the frame class was constructed). Their slots
are filled from the exjava objects with which they were constructed,
and they are then validated.
buildFrame
public void buildFrame()
- Fills in the slots for this frame from the underlying exjava UserFnCall
object.
getFrameClass
public FrameClass getFrameClass()
- Returns the frame class of this frame.
- Returns:
- The frame class of this frame.
- Overrides:
- getFrameClass in class Frame
writeClass
public static void writeClass(ObjectOutput oo) throws IOException
- Serialises the static data members (class variables) of
UserFnCallFrame.
- Parameters:
- oo - An output object to save the class data to.
- Throws: IOException
- If an I/O exception occurs.
readClass
public static void readClass(ObjectInput oi) throws IOException
- Deserialises the static data members (class variables) of
UserFnCallFrame.
- Parameters:
- ois - An input object to save the class data to.
- Throws: IOException
- If an I/O exception occurs.
