Interface InsertionOperatorFactory

public interface InsertionOperatorFactory

Factory interface for creating insertion strategies.

This allows registering insertion operators with the algorithm builder without needing to pre-create all dependencies. The factory will be called during algorithm construction when all dependencies are available.

Example usage:

 Jsprit.Builder.newInstance(vrp)
     .addInsertionOperator(0.7, Insertion.regretFast())
     .addInsertionOperator(0.3, Insertion.regret())
     .buildAlgorithm();

Method Details

create

InsertionStrategy create(InsertionOperatorFactory.Context context)

Creates an insertion strategy with the given dependencies.

Parameters:

context - the context containing all required dependencies

Returns:

the configured insertion strategy

getName

default String getName()

Returns the default name for this operator factory.

This name is used in strategy IDs when no explicit name is provided to addInsertionOperator().

Returns:

the default name, or null if not specified

named

static InsertionOperatorFactory named(String name,
 InsertionOperatorFactory factory)

Creates a named factory wrapper.

Parameters:

name - the operator name

factory - the factory to wrap

Returns:

a factory that returns the given name from getName()
