Description copied from class: AbstractModel

Called by aggregate sets when a term has been removed from a term iterator. Exactly one of the last four terms will be non-empty.

Specified by:

removeTermIteration in class AbstractModel

Parameters:

iter - The iterator used to navigate the live set (never null)

s - the subject term to be removed or null

p - the predicate term to be removed or null

o - the object term to be removed or null

c - an array of one context term to be removed or an empty array

                                                    Value obj,
                                                    Resource... contexts)

Called by aggregate sets when a term has been removed from a term iterator. At least one of the last four terms will be non-empty.

Parameters:

iter - The iterator used to navigate the live set (never null)

subj - the subject term to be removed or null

pred - the predicate term to be removed or null

obj - the object term to be removed or null

contexts - an array of one context term to be removed or an empty array
