Class InjectorJitBindingData

java.lang.Object

com.google.inject.internal.InjectorJitBindingData

final class InjectorJitBindingData
extends java.lang.Object

A container for most just-in-time (JIT) binding data corresponding to an Injector. It includes @Inject constructor bindings. It does not include MembersInjectorStore or ProvisionListenerCallbackStore, which are still stored in InjectorImpl.

Field Detail

jitBindings

private final java.util.Map<Key<?>,BindingImpl<?>> jitBindings

Just-in-time binding cache. Guarded by lock.

failedJitBindings

private final java.util.Set<Key<?>> failedJitBindings

Cache of Keys that we were unable to create JIT bindings for, so we don't keep trying. Guarded by lock.

bannedKeys

private final WeakKeySet bannedKeys

parent

private final java.util.Optional<InjectorJitBindingData> parent

lock

private final java.lang.Object lock

This lock is needed for threadsafe InjectorJitBindingData accesses. It corresponds to this InjectorJitBindingData's highest ancestor.

Method Detail

getJitBindings

java.util.Map<Key<?>,BindingImpl<?>> getJitBindings()

getJitBinding

BindingImpl<?> getJitBinding(Key<?> key)

putJitBinding

void putJitBinding(Key<?> key,
                   BindingImpl<?> binding)

removeJitBinding

void removeJitBinding(Key<?> key)

isFailedJitBinding

boolean isFailedJitBinding(Key<?> key)

addFailedJitBinding

void addFailedJitBinding(Key<?> key)

banKey

void banKey(Key<?> key,
            InjectorBindingData injectorBindingData,
            java.lang.Object source)

Forbids the corresponding injector and its ancestors from creating a binding to key. Child injectors ban their bound keys on their parent injectors to prevent just-in-time bindings on the parent injector that would conflict, and pass along their InjectorBindingData to control the banned key's lifetime.

banKeyInParent

void banKeyInParent(Key<?> key,
                    InjectorBindingData injectorBindingData,
                    java.lang.Object source)

Similar to banKey(Key, InjectorBindingData, Object) but we only begin banning the binding at the parent level. This is used to prevent JIT bindings in the parent injector from overriding explicit bindings declared in a child injector.

isBannedKey

boolean isBannedKey(Key<?> key)

Returns true if key is forbidden from being bound in the injector corresponding to this data object. This indicates that one of the injector's children has bound the key.

getSourcesForBannedKey

java.util.Set<java.lang.Object> getSourcesForBannedKey(Key<?> key)

Returns the source of a banned key.

lock

java.lang.Object lock()
