public AbstractConfigContext()

Method Detail

wrapContext

protected static LenskitConfigContext wrapContext(Context ctx)

Coerce a Grapht context to a LensKit context.

Parameters:

ctx - The context.

Returns:

A LensKit context, as a wrapper if necessary.

bind

public <T> LenskitBinding<T> bind(Class<? extends Annotation> qual,
                                  Class<T> type)

Specified by:

bind in interface Context

Specified by:

bind in interface LenskitConfigContext

Overrides:

bind in class AbstractContext

bindAny

public <T> LenskitBinding<T> bindAny(Class<T> type)

Specified by:

bindAny in interface Context

Specified by:

bindAny in interface LenskitConfigContext

Overrides:

bindAny in class AbstractContext

set

public Binding set(@Nonnull
                   Class<? extends Annotation> param)

Description copied from interface: LenskitConfigContext

Start a binding that sets a parameter. Parameters are qualifiers that bear the Parameter annotation.

Specified by:

set in interface LenskitConfigContext

Parameters:

param - The parameter to set.

Returns:

The binding for this parameter. It is untyped, as many types will be accepted and attempted.

addComponent

public void addComponent(@Nonnull
                         Object obj)

Description copied from interface: LenskitConfigContext

Add a component object to the injector. This is the equivalent of:

 this.bind(obj.getClass()).to(obj);
 

It has the result of making obj available satisfy dependencies on its class or, via supertype binding generation, any of its supertypes. Explicit bindings for those supertypes will override this binding.

Specified by:

addComponent in interface LenskitConfigContext

Parameters:

obj - The object to register.

addComponent

public void addComponent(@Nonnull
                         Class<?> type)

Description copied from interface: LenskitConfigContext

Add a component type to the injector. This is the equivalent of:

 this.bind(type).to(type);
 

It has the result of making type available satisfy dependencies on itself or, via supertype binding generation, any of its supertypes. Explicit bindings for those supertypes will override this binding.

Specified by:

addComponent in interface LenskitConfigContext

Parameters:

type - The type to register.
