Method Detail

getSource

public Object getSource()

Description copied from interface: Element

Returns an arbitrary object containing information about the "place" where this element was configured. Used by Guice in the production of descriptive error messages.

Tools might specially handle types they know about; StackTraceElement is a good example. Tools should simply call toString() on the source object if the type is unfamiliar.

Specified by:

getSource in interface Element

getElements

public List<Element> getElements()

Description copied from interface: PrivateElements

Returns the configuration information in this private environment.

Specified by:

getElements in interface PrivateElements

getInjector

public Injector getInjector()

Description copied from interface: PrivateElements

Returns the child injector that hosts these private elements, or null if the elements haven't been used to create an injector.

Specified by:

getInjector in interface PrivateElements

initInjector

public void initInjector(Injector injector)

getExposedKeys

public Set<Key<?>> getExposedKeys()

Description copied from interface: PrivateElements

Returns the unique exposed keys for these private elements.

Specified by:

getExposedKeys in interface PrivateElements

acceptVisitor

public <T> T acceptVisitor(ElementVisitor<T> visitor)

Description copied from interface: Element

Accepts an element visitor. Invokes the visitor method specific to this element's type.

Specified by:

acceptVisitor in interface Element

Parameters:

visitor - to call back on

getElementsMutable

public List<Element> getElementsMutable()

addExposureBuilder

public void addExposureBuilder(ExposureBuilder<?> exposureBuilder)

applyTo

public void applyTo(Binder binder)

Description copied from interface: Element

Writes this module element to the given binder (optional operation).

Specified by:

applyTo in interface Element

Parameters:

binder - to apply configuration element to

getExposedSource

public Object getExposedSource(Key<?> key)

Description copied from interface: PrivateElements

Returns an arbitrary object containing information about the "place" where this key was exposed. Used by Guice in the production of descriptive error messages.

Tools might specially handle types they know about; StackTraceElement is a good example. Tools should simply call toString() on the source object if the type is unfamiliar.

Specified by:

getExposedSource in interface PrivateElements

Parameters:

key - one of the keys exposed by this module.

toString

public String toString()

Overrides:

toString in class Object
