+----BuiltInFnCallFrame
- public class BuiltInFnCallFrame
- extends Frame
The class `BuiltInFnCallFrame', a subclass of Frame,
represents a frame internally as an exjava BuiltInFnCall object - such frames
should only be used to represent built-in function calls in EXPRESS models.
-
BuiltInFnCallFrame(BuiltInFnCall, Frame)
- Constructs this frame by plugging in the given exjava BuiltInFnCall object
(it does so by copying the reference, which is maximally efficient
but the client should not then alter the BuiltInFnCall directly, as that
would compromise the integrity of the frame).
-
BuiltInFnCallFrame(BuiltInFnCall, Frame, Hashtable)
- Constructs this frame by plugging in the given exjava BuiltInFnCall object
(it does so by copying the reference, which is maximally efficient,
but the client should not then alter the BuiltInFnCall directly, as that
would compromise the integrity of the frame).
-
buildFrame()
- Fills in the slots for this frame from the underlying exjava BuiltInFnCall
object.
-
buildQueuedFrames()
- Builds any BuiltInFnCall 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 BuiltInFnCallFrame class by setting the class
variable _frameClass after looking up the `built_in_function_call'
entity in the given EXPRESS (meta)model.
-
readClass(ObjectInput)
- Deserialises the static data members (class variables) of
BuiltInFnCallFrame.
-
writeClass(ObjectOutput)
- Serialises the static data members (class variables) of
BuiltInFnCallFrame.
BuiltInFnCallFrame
public BuiltInFnCallFrame(BuiltInFnCall instanceData,
Frame theEntity) throws FrameAlreadyExists
- Constructs this frame by plugging in the given exjava BuiltInFnCall object
(it does so by copying the reference, which is maximally efficient
but the client should not then alter the BuiltInFnCall directly, as that
would compromise the integrity of the frame).
- Parameters:
- instanceData - An exjava BuiltInFnCall object to wrap in this frame.
- theEntity - The entity which contains this function call.
- Throws: FrameAlreadyExists
- If an BuiltInFnCall has already been
constructed for `instanceData'.
BuiltInFnCallFrame
public BuiltInFnCallFrame(BuiltInFnCall instanceData,
Frame theEntity,
Hashtable moreInstanceData) throws FrameAlreadyExists
- Constructs this frame by plugging in the given exjava BuiltInFnCall object
(it does so by copying the reference, which is maximally efficient,
but the client should not then alter the BuiltInFnCall 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 BuiltInFnCall 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 BuiltInFnCall has already been
constructed for `instanceData'.
initialise
public static void initialise(Express metamodel)
- Initialises the BuiltInFnCallFrame class by setting the class
variable _frameClass after looking up the `built_in_function_call'
entity in the given EXPRESS (meta)model.
- Parameters:
- metamodel - An EXPRESS metamodel, which is expected to contain
the entity `built_in_function_call'.
buildQueuedFrames
public static void buildQueuedFrames()
- Builds any BuiltInFnCall 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 BuiltInFnCall
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
BuiltInFnCallFrame.
- 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
BuiltInFnCallFrame.
- Parameters:
- ois - An input object to save the class data to.
- Throws: IOException
- If an I/O exception occurs.
