All Classes

Class	Description
Assertions
BatchLoader<K,V>	A function that is invoked for batch loading a list of data values indicated by the provided list of keys.
BatchLoaderContextProvider	A BatchLoaderContextProvider is used by the DataLoader code to provide overall calling context to the BatchLoader call.
BatchLoaderEnvironment	This object is passed to a batch loader as calling context.
BatchLoaderEnvironment.Builder
BatchLoaderEnvironmentProvider	A BatchLoaderEnvironmentProvider is used by the DataLoader code to provide BatchLoaderEnvironment calling context to the BatchLoader call.
BatchLoaderWithContext<K,V>	This form of BatchLoader is given a BatchLoaderEnvironment object that encapsulates the calling context.
CacheKey<K>	Function that is invoked on input keys of type K to derive keys that are required by the CacheMap implementation.
CacheMap<K,V>	CacheMap is used by data loaders that use caching promises to values aka CompletableFuture<V>.
CompletableFutureKit	Some really basic helpers when working with CompletableFutures
DataLoader<K,V>	Data loader is a utility class that allows batch loading of data that is identified by a set of unique keys.
DataLoaderAssertionException
DataLoaderFactory	A factory class to create DataLoaders
DataLoaderHelper<K,V>	This helps break up the large DataLoader class functionality and it contains the logic to dispatch the promises on behalf of its peer dataloader
DataLoaderHelper.LoaderQueueEntry<K,V>
DataLoaderOptions	Configuration options for DataLoader instances.
DataLoaderRegistry	This allows data loaders to be registered together into a single place so they can be dispatched as one.
DataLoaderRegistry.Builder
DefaultCacheMap<K,V>	Default implementation of CacheMap that is based on a regular HashMap.
DelegatingStatisticsCollector	This statistics collector keeps dataloader statistics AND also calls the delegate collector at the same time.
DispatchPredicate	A predicate class used by ScheduledDataLoaderRegistry to decide whether to dispatch or not
DispatchResult<T>	When a DataLoader is dispatched this object holds the promised results and also the count of key asked for via methods like DataLoader.load(Object) or DataLoader.loadMany(java.util.List)
ExperimentalApi	This represents code that the graphql-java project considers experimental API and while our intention is that it will progress to be PublicApi, its existence, signature of behavior may change between releases.
GuardedBy	Indicates that the annotated element should be used only while holding the specified lock.
IncrementBatchLoadCountByStatisticsContext<K>
IncrementBatchLoadExceptionCountStatisticsContext<K>
IncrementCacheHitCountStatisticsContext<K>
IncrementLoadCountStatisticsContext<K>
IncrementLoadErrorCountStatisticsContext<K>
Internal	This represents code that the java-dataloader project considers internal code that MAY not be stable within major releases.
MappedBatchLoader<K,V>	A function that is invoked for batch loading a map of of data values indicated by the provided set of keys.
MappedBatchLoaderWithContext<K,V>	This form of MappedBatchLoader is given a BatchLoaderEnvironment object that encapsulates the calling context.
NoOpStatisticsCollector	A statistics collector that does nothing
NoOpValueCache<K,V>	Implementation of ValueCache that does nothing.
PromisedValues<T>	This allows multiple CompletionStages to be combined together and completed as one and should something go wrong, instead of throwing CompletionExceptions it captures the cause and returns null for that data value, other wise it allows you to access them as a list of values.
PromisedValuesImpl<T>
PublicApi	This represents code that the java-dataloader project considers public API and has an imperative to be stable within major releases.
PublicSpi	This represents code that the java-dataloader project considers public SPI and has an imperative to be stable within major releases.
ScheduledDataLoaderRegistry	This DataLoaderRegistry will use a DispatchPredicate when ScheduledDataLoaderRegistry.dispatchAll() is called to test (for each DataLoader in the registry) if a dispatch should proceed.
ScheduledDataLoaderRegistry.Builder
SimpleStatisticsCollector	This simple collector uses AtomicLongs to collect statistics
Statistics	This holds statistics on how a DataLoader has performed
StatisticsCollector	This allows statistics to be collected for DataLoader operations
ThreadLocalStatisticsCollector	This can collect statistics per thread as well as in an overall sense.
Try<V>	Try is class that allows you to hold the result of computation or the throwable it produced.
ValueCache<K,V>	The ValueCache is used by data loaders that use caching and want a long-lived or external cache of values.
ValueCache.ValueCachingNotSupported	This special exception can be used to short-circuit a caching method
ValueCacheOptions	Options that control how the ValueCache is used by DataLoader
VisibleForTesting	Marks fields, methods etc as more visible than actually needed for testing purposes.
