Method Detail

setClassLoader

public void setClassLoader(ClassLoader loader)

addBindings

public RecommenderGraphBuilder addBindings(BindingFunctionBuilder bld)

Add bindings to the graph builder. Bindings added to this builder are processed in the reverse order as DependencySolverBuilder - add the most important bindings last.

Parameters:

bld - A builder of the bindings to add.

Returns:

The graph builder.

addRoots

public RecommenderGraphBuilder addRoots(Iterable<Class<?>> classes)

Add roots to the graph builder.

Parameters:

classes - Root types for the graph.

Returns:

The graph builder (for chaining).

addConfiguration

public RecommenderGraphBuilder addConfiguration(LenskitConfiguration config)

Add a recommender configuration.

Parameters:

config - The configuration.

Returns:

The graph builder (for chaining).

buildDependencySolver

public DependencySolver buildDependencySolver()

Build a dependency solver from the provided bindings.

Returns:

The dependency solver.

buildDependencyUnsolver

public DependencySolver buildDependencyUnsolver()

Build a dependency 'unsolver' from the provided bindings. The resulting solver, when rewriting a graph, will replace bound targets with placeholders.

Returns:

The dependency solver.

buildDependencySolverImpl

public DependencySolver buildDependencySolverImpl(org.grouplens.lenskit.inject.RecommenderGraphBuilder.SolveDirection direction)

buildGraph

public DAGNode<Component,Dependency> buildGraph()
                                         throws ResolutionException

Throws:

ResolutionException
