com.google.inject.internal.InjectorJitBindingData

Imports

com.google.common.collect.Maps, .Sets, com.google.inject.Key, java.util.Collections, .Map, .Optional, .Set

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 Summary

Modifier and Type	Field and Description
private final WeakKeySet	bannedKeys
private final Set<Key<?>>	failedJitBindings Cache of Keys that we were unable to create JIT bindings for, so we don't keep trying.
private final Map<Key<?>, BindingImpl<?>>	jitBindings Just-in-time binding cache.
private final Object	lock This lock is needed for threadsafe InjectorJitBindingData accesses.
private final Optional<InjectorJitBindingData>	parent

Method Summary

Modifier and Type	Method and Description
pack-priv void	addFailedJitBinding(Key<?> key)
pack-priv void	banKey(Key<?> key, InjectorBindingData injectorBindingData, Object source) Forbids the corresponding injector and its ancestors from creating a binding to `key`.
pack-priv void	banKeyInParent(Key<?> key, InjectorBindingData injectorBindingData, Object source) Similar to `banKey(Key, InjectorBindingData, Object)` but we only begin banning the binding at the parent level.
pack-priv BindingImpl<?>	getJitBinding(Key<?> key)
pack-priv Map<Key<?>, BindingImpl<?>>	getJitBindings()
pack-priv Set<Object>	getSourcesForBannedKey(Key<?> key) Returns the source of a banned key.
pack-priv boolean	isBannedKey(Key<?> key) Returns true if `key` is forbidden from being bound in the injector corresponding to this data object.
pack-priv boolean	isFailedJitBinding(Key<?> key)
pack-priv Object	lock()
pack-priv void	putJitBinding(Key<?> key, BindingImpl<?> binding)
pack-priv void	removeJitBinding(Key<?> key)

Field Detail

bannedKeys	back to summary
private final WeakKeySet bannedKeys

failedJitBindings	back to summary
private final Set<Key<?>> failedJitBindings Cache of Keys that we were unable to create JIT bindings for, so we don't keep trying. Guarded by `lock`.

jitBindings	back to summary
private final Map<Key<?>, BindingImpl<?>> jitBindings Just-in-time binding cache. Guarded by `lock`.

lock	back to summary
private final Object lock This lock is needed for threadsafe InjectorJitBindingData accesses. It corresponds to this InjectorJitBindingData's highest ancestor.

private final Optional<InjectorJitBindingData> parent

Method Detail

addFailedJitBinding	back to summary
pack-priv void addFailedJitBinding(Key<?> key)

banKey	back to summary
pack-priv void banKey(Key<?> key, InjectorBindingData injectorBindingData, 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	back to summary
pack-priv void banKeyInParent(Key<?> key, InjectorBindingData injectorBindingData, 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.

getJitBinding	back to summary
pack-priv BindingImpl<?> getJitBinding(Key<?> key)

getJitBindings	back to summary
pack-priv Map<Key<?>, BindingImpl<?>> getJitBindings()

getSourcesForBannedKey	back to summary
pack-priv Set<Object> getSourcesForBannedKey(Key<?> key) Returns the source of a banned key.

isBannedKey	back to summary
pack-priv 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.

isFailedJitBinding	back to summary
pack-priv boolean isFailedJitBinding(Key<?> key)

lock	back to summary
pack-priv Object lock()

putJitBinding	back to summary
pack-priv void putJitBinding(Key<?> key, BindingImpl<?> binding)

removeJitBinding	back to summary
pack-priv void removeJitBinding(Key<?> key)
