Method Detail

again

public FeRangeElement again()

Description copied from class: FeRangeElement

Essential. An object reflecting the current identity of this object, in case it is a
PlaceHolder that has become something else since it was received from the Server.

Overrides:

again in class FePlaceHolder

canMakeIdentical

public boolean canMakeIdentical(FeRangeElement newIdentity)

Description copied from class: FeRangeElement

Essential. Whether the identity of this object could be changed to the other.
Does not check whether the CurrentKeyMaster has authority to do it.
The restrictions on this operation depend on which subclass this is, but in general
(except for PlaceHolders) an object can only become another of the same type with the same
content.

Overrides:

canMakeIdentical in class FePlaceHolder

makeIdentical

public void makeIdentical(FeRangeElement newIdentity)

Consolidate this PlaceHolder to the newIdentity. Return true if successful.

Overrides:

makeIdentical in class FePlaceHolder

owner

public ID owner()

Description copied from class: FeRangeElement

Essential. The Club which owns this RangeElement, and has the authority to make it become
something else, and to transfer ownership to someone else.

Overrides:

owner in class FeRangeElement

removeFillDetector

public void removeFillDetector(FeFillDetector detector)

Description copied from class: FeRangeElement

Essential. Remove a Detector which had been added to this RangeElement. You should remove
every Detector you add, although they will go away automatically when a client session
terminates.

Overrides:

removeFillDetector in class FeRangeElement

fetchBe

public BeRangeElement fetchBe()

Description copied from class: FeRangeElement

If this has a reified Be object, then return it, else NULL

Overrides:

fetchBe in class FePlaceHolder

getOrMakeBe

public BeRangeElement getOrMakeBe()

Force the ent to generate a beRangeElement at myKey.

Overrides:
