def anonymousLinkOK( self, targetObject, targetFieldID, sourceObject,
sourceFieldID, gsession ):
'''
This method is used to control whether or not it is acceptable to make a
link to the given field in this {@link arlut.csd.ganymede.server.DBObject
DBObject} type when the user only has editing access for the source {@link
arlut.csd.ganymede.server.InvidDBField InvidDBField} and not the target.
This version of anonymousLinkOK takes additional parameters to allow an
object type to decide that it does or does not want to allow a link based
on what field of what object wants to link to it.
By default, the 3 variants of the DBEditObject anonymousLinkOK() method are
chained together, so that the customizer can choose which level of detail
he is interested in. {@link arlut.csd.ganymede.server.InvidDBField
InvidDBField}s {@link arlut.csd.ganymede.server.InvidDBField#bind(
arlut.csd.ganymede.common.Invid,arlut.csd.ganymede.common.Invid,boolean)
bind()} method calls this version. This version calls the three parameter
version, which calls the two parameter version, which returns false by
default. Customizers can implement any of the three versions, but unless
you maintain the version chaining yourself, theres no point to
implementing more than one of them.
