public class AggTypeFrame
extends Frame
The class `AggTypeFrame', a subclass of Frame, represents a frame internally as an exjava AggType object - such frames should only be used to represent aggregation types in EXPRESS models.


Constructor Index

 o AggTypeFrame(AggType)
Constructs this frame by plugging in the given exjava AggType object (it does so by copying the reference, which is maximally efficient but the client should not then alter the AggType directly, as that would compromise the integrity of the frame).
 o AggTypeFrame(AggType, Hashtable)
Constructs this frame by plugging in the given exjava AggType object (it does so by copying the reference, which is maximally efficient, but the client should not then alter the AggType directly, as that would compromise the integrity of the frame).

Method Index

 o buildFrame()
Fills in the slots for this frame from the underlying exjava AggType object.
 o buildQueuedFrames()
Builds any AggType Frames that are queued to be built (those that were constructed before the frame class was constructed).
 o getFrameClass()
Returns the frame class of this frame.
 o initialise(Express)
Initialises the AggTypeFrame class by setting the class variable _frameClass after looking up the `aggregation_type' entity in the given EXPRESS (meta)model.
 o readClass(ObjectInput)
Deserialises the static data members (class variables) of AggTypeFrame.
 o writeClass(ObjectOutput)
Serialises the static data members (class variables) of AggTypeFrame.

Constructors

 o AggTypeFrame
 public AggTypeFrame(AggType instanceData) throws FrameAlreadyExists
Constructs this frame by plugging in the given exjava AggType object (it does so by copying the reference, which is maximally efficient but the client should not then alter the AggType directly, as that would compromise the integrity of the frame).

Parameters:
instanceData - An exjava AggType object to wrap in this frame.
Throws: FrameAlreadyExists
If an AggType has already been constructed for `instanceData'.
 o AggTypeFrame
 public AggTypeFrame(AggType instanceData,
                     Hashtable moreInstanceData) throws FrameAlreadyExists
Constructs this frame by plugging in the given exjava AggType object (it does so by copying the reference, which is maximally efficient, but the client should not then alter the AggType directly, as that would compromise the integrity of the frame). This constructor allows the aggregation type frame to be tagged with extra slots, given in a hash table.

Parameters:
instanceData - An exjava AggType object to wrap in this frame.
moreInstanceData - Extra slots to tag this aggregation type frame with.
Throws: FrameAlreadyExists
If an AggType has already been constructed for `instanceData'.

Methods

 o initialise
 public static void initialise(Express metamodel)
Initialises the AggTypeFrame class by setting the class variable _frameClass after looking up the `aggregation_type' entity in the given EXPRESS (meta)model.

Parameters:
metamodel - An EXPRESS metamodel, which is expected to contain the entity `aggregation_type'.
 o buildQueuedFrames
 public static void buildQueuedFrames()
Builds any AggType 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.

 o buildFrame
 public void buildFrame()
Fills in the slots for this frame from the underlying exjava AggType object.

 o getFrameClass
 public FrameClass getFrameClass()
Returns the frame class of this frame.

Returns:
The frame class of this frame.
Overrides:
getFrameClass in class Frame
 o writeClass
 public static void writeClass(ObjectOutput oo) throws IOException
Serialises the static data members (class variables) of AggTypeFrame.

Parameters:
oo - An output object to save the class data to.
Throws: IOException
If an I/O exception occurs.
 o readClass
 public static void readClass(ObjectInput oi) throws IOException
Deserialises the static data members (class variables) of AggTypeFrame.

Parameters:
ois - An input object to save the class data to.
Throws: IOException
If an I/O exception occurs.
