ch.jalu.injector.handlers.instantiation

Interface Resolution<T>

Type Parameters:

T - the type of the requested object

All Known Implementing Classes:

SimpleResolution, StandardInjection

public interface Resolution<T>

An object resolution knows how to provide the requested object. Some resolutions simply wrap an existing value (e.g. if a requested singleton has already been created), others may define dependencies which must be provided so that it can create the object.

Method Summary

Modifier and Type	Method and Description
List<ObjectIdentifier>	getDependencies() Returns the dependencies that must be provided to create or retrieve the requested object.
T	instantiateWith(Object... values) Creates or retrieves an object with the given values as dependencies.
default boolean	isInstantiation() Returns whether this resolution will instantiate an object or not.

Method Detail

getDependencies

List<ObjectIdentifier> getDependencies()

Returns the dependencies that must be provided to create or retrieve the requested object.

Returns:

list of dependencies

See Also:

instantiateWith(java.lang.Object...)

instantiateWith

T instantiateWith(Object... values)

Creates or retrieves an object with the given values as dependencies. The given values must correspond to getDependencies() in size, order and type (as given by ObjectIdentifier.getType().

Parameters:

values - the required dependencies

Returns:

the resulting object

isInstantiation

default boolean isInstantiation()

Returns whether this resolution will instantiate an object or not. Certain resolutions simply need to retrieve an existing object; this method returns true when the requested object has to be instantiated.

Returns:

true if a newly created object will be returned, false if the object already exists
