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