| 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. |
| 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 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. |
| ValueCache<K,V> |
The
ValueCache is used by data loaders that use caching and want a long-lived or external cache
of values. |
| 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 | Description |
|---|---|
| ValueCache.ValueCachingNotSupported |
This special exception can be used to short-circuit a caching method
