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