Method Detail

create

static <K,V> VertxMappedBatchLoader<K,V> create(TriConsumer<Set<K>,org.dataloader.BatchLoaderEnvironment,Promise<Map<K,V>>> batchLoader)

Create a new batch loader that works well with callback based APIs.

The provided batchLoader will be invoked with the following arguments:

• the keys for the data objects that should be loaded
• the BatchLoaderEnvironment
• a Promise that the implementor must complete after the data objects are loaded

create

static <K,V> VertxMappedBatchLoader<K,V> create(TriConsumer<Set<K>,org.dataloader.BatchLoaderEnvironment,Promise<Map<K,V>>> batchLoader,
                                                java.util.function.Function<org.dataloader.BatchLoaderEnvironment,Context> contextProvider)

Like create(TriConsumer), except the method uses the provided contextProvider instead of capturing the current one.

create

static <K,V> VertxMappedBatchLoader<K,V> create(java.util.function.BiFunction<Set<K>,org.dataloader.BatchLoaderEnvironment,Future<Map<K,V>>> batchLoader)

Create a new batch loader that works well with Future based APIs.

The provided batchLoader will be invoked with the following arguments:

• the keys for the data objects that should be loaded
• the BatchLoaderEnvironment

create

static <K,V> VertxMappedBatchLoader<K,V> create(java.util.function.BiFunction<Set<K>,org.dataloader.BatchLoaderEnvironment,Future<Map<K,V>>> batchLoader,
                                                java.util.function.Function<org.dataloader.BatchLoaderEnvironment,Context> contextProvider)

Like create(BiFunction), except the method uses the provided contextProvider instead of capturing the current one.
