public interface ModelChangedListener
The interface for classes that listen for model-changed events. In all cases,
the argument is [a copy of] the item that has been presented to the model,
or its underlying graph, for addition or removal. For an add, the item [or parts
of that item] may have already been present in the model; for remove, the
item [or parts of it] need not have been absent from the item.
NOTE that the listener is supplied with more-or-less faithful copies of the original items that were added to, or removed from, the model. In particular, graph-level updates to the model appear as statements, not triples.

Method Details
-
addedStatement
Method to call when a single statement has been added to the attached model.- Parameters:
s
- the statement that has been presented for addition.
-
addedStatements
Method to call when an array of statements has been added to the attached model. NOTE. This array need not be == to the array added using Model::add(Statement[]).- Parameters:
statements
- the array of added statements
-
addedStatements
Method to call when a list of statements has been added to the attached model. NOTE. This list need not be == to the list added using Model::add(List).- Parameters:
statements
- the list of statements that has been removed.
-
addedStatements
Method to call when a statement iterator has supplied elements to be added to the attached model.statements
is a copy of the original iterator.- Parameters:
statements
-
-
addedStatements
Method to call when a model has been used to define the statements to be added to our attached model.- Parameters:
m
- a model equivalent to [and sharing with] the added model
-
removedStatement
Method to call when a single statement has been removed from the attached model.- Parameters:
s
- the statement that has been presented for removal.
-
removedStatements
Method to call when an array of statements has been removed from the attached model. NOTE. This array need not be == to the array added using Model::remove(Statement[]).- Parameters:
statements
- the array of removed statements
-
removedStatements
Method to call when a list of statements has been deleted from the attached model. NOTE. This list need not be == to the list added using Model::remove(List).- Parameters:
statements
- the list of statements that have been removed.
-
removedStatements
Method to call when a statement iterator has been used to remove statements from the attached model. The iterator will be a copy, in the correct order, of the iterator supplied for the removal.- Parameters:
statements
- a statement-type copy of the updating iterator
-
removedStatements
Method to call when a model has been used to remove statements from our attached model.- Parameters:
m
- a model equivalent to [and sharing with] the one removed
