Field Details

options

private final InjectorImpl.InjectorOptions options

constructionContexts

private final IdentityHashMap<Object,ConstructionContext<?>> constructionContexts

dependency

private Dependency<?> dependency

Keeps track of the type that is currently being requested for injection.

enterCount

private int enterCount

The number of times enter() has been called + 1 for initial construction. This value is decremented when

invalid reference

#exit()

is called.

toClear

private final Object[] toClear

A single element array to clear when the enterCount hits 0.

This is the value stored in the InjectorImpl.localContext thread local.

Constructor Details

InternalContext

InternalContext(InjectorImpl.InjectorOptions options,
 Object[] toClear)

Method Details

enter

void enter()

Should only be called by InjectorImpl.enterContext().

close

public void close()

Should be called any any method that received an instance via InjectorImpl.enterContext().

Specified by:

close in interface AutoCloseable

getInjectorOptions

InjectorImpl.InjectorOptions getInjectorOptions()

getConstructionContext

<T> ConstructionContext<T> getConstructionContext(Object key)

getDependency

Dependency<?> getDependency()

setDependency

void setDependency(Dependency<?> dependency)

Used to set the current dependency.

The currentDependency field is only used by InternalFactoryToProviderAdapter to propagate information to singleton scope. See comments in that class about alternatives.
