Interface ModelChangedListener

All Known Implementing Classes:

ChangedListener, NullListener, ObjectListener, StatementListener

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 Detail

addedStatement

void addedStatement(Statement s)

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

void addedStatements(Statement[] statements)

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

void addedStatements(java.util.List<Statement> statements)

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

void addedStatements(StmtIterator statements)

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

void addedStatements(Model m)

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

void removedStatement(Statement s)

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

void removedStatements(Statement[] statements)

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

void removedStatements(java.util.List<Statement> statements)

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::remov(List).

Parameters:

statements - the list of statements that have been removed.

removedStatements

void removedStatements(StmtIterator statements)

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

void removedStatements(Model m)

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

notifyEvent

void notifyEvent(Model m,
                 java.lang.Object event)
