Package org.dataloader

Interface Summary

Interface	Description
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.
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.
BatchPublisher<K,V>	A function that is invoked for batch loading a stream of data values indicated by the provided list of keys.
BatchPublisherWithContext<K,V>	This form of BatchPublisher 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>.
MappedBatchLoader<K,V>	A function that is invoked for batch loading a map 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.
MappedBatchPublisher<K,V>	A function that is invoked for batch loading a stream of data values indicated by the provided list of keys.
MappedBatchPublisherWithContext<K,V>	This form of MappedBatchPublisher is given a BatchLoaderEnvironment object that encapsulates the calling context.
ValueCache<K,V>	The ValueCache is used by data loaders that use caching and want a long-lived or external cache of values.

Class Summary

Class	Description
BatchLoaderEnvironment	This object is passed to a batch loader as calling context.
BatchLoaderEnvironment.Builder
DataLoader<K,V>	Data loader is a utility class that allows batch loading of data that is identified by a set of unique keys.
DataLoaderFactory	A factory class to create DataLoaders
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
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)
Try<V>	Try is class that allows you to hold the result of computation or the throwable it produced.
ValueCacheOptions	Options that control how the ValueCache is used by DataLoader

Exception Summary

Exception	Description
ValueCache.ValueCachingNotSupported	This special exception can be used to short-circuit a caching method
