Constructor Detail

BeRangeElement

public BeRangeElement()

BeRangeElement

public BeRangeElement(SensorCrum sensorCrum)

BeRangeElement

public BeRangeElement(Rcvr receiver)

Method Detail

addFeRangeElement

public void addFeRangeElement(FeRangeElement element)

Add a new session level pointer

isPurgeable

public boolean isPurgeable()

Description copied from class: Abraham

Return false only if the object cannot be flushed to disk. This will probably
only be false for Stamps and the like that contain session level pointers.

Overrides:

isPurgeable in class Abraham

makeFe

public FeRangeElement makeFe(BeLabel label)

Make a front end object (session level) for this backend object. If the receiver is an
Edition, there had better be a label.

makeIdentical

public boolean makeIdentical(BeRangeElement other)

Change the identity of this object to that of the other.
Only placeHolders implement it at the moment, so the
default is to reject the operation (return false).

owner

public ID owner()

The Club who has ownership

removeFeRangeElement

public void removeFeRangeElement(FeRangeElement element)

Remove a session level pointer

setOwner

public void setOwner(ID club)

Change the Club who has ownership

addOParent

public void addOParent(Loaf oparent)

add oparent to the set of upward pointers. Editions may
also have to propagate BertCrum change downward.

anyPasses

public boolean anyPasses(PropFinder finder)

bertCrum

public BertCrum bertCrum()

checkRecorders

public void checkRecorders(PropFinder finder,
                           SensorCrum scrum)

does nothing. Overrides do something.

contentsHash

public int contentsHash()

Description copied from class: Abraham

A hash of the contents of this flock

Overrides:

contentsHash in class Abraham

delayedStoreBackfollow

public void delayedStoreBackfollow(PropFinder finder,
                                   RecorderFossil fossil,
                                   ResultRecorder recorder,
                                   HashSetCache hCrumCache)

feRangeElements

public PrimSet feRangeElements()

hCrum

public HistoryCrum hCrum()

inTrace

public boolean inTrace(TracePosition trace)

Return true if the receiver can backfollow to trace.

mappingTo

public Mapping mappingTo(TracePosition trace,
                         Mapping mapping)

return a mapping from my data to corresponding stuff in the given trace

removeOParent

public void removeOParent(OPart oparent)

remove oparent from the set of upward pointers.

sensorCrum

public SensorCrum sensorCrum()

updateBCrumTo

public boolean updateBCrumTo(BertCrum newBCrum)

Ensure the my bertCrum is not be leafward of newBCrum.

dismantle

public void dismantle()

Description copied from class: Abraham

Disconnect me from the universe and throw me off the disk.
For GC safety, we keep a strongptr to ourself -- is this still necessary?

Overrides:

dismantle in class Abraham

restartRE

public void restartRE(Rcvr rcvr)

inspect

public void inspect()

Sensor leftShiftDown

Overrides:

inspect in class AboraHeaper

delayedStoreBackfollow

public void delayedStoreBackfollow(PropFinder finder,
                                   RecorderFossil recorder,
