Uses of Projection in com.hazelcast.jet.core.processor

Methods in com.hazelcast.jet.core.processor with parameters of type Projection

Modifier and Type	Method	Description
static <T, K, V> ProcessorMetaSupplier	SourceProcessors.readMapP(String mapName, Predicate<K,V> predicate, Projection<? super Map.Entry<K,V>,? extends T> projection)	Returns a supplier of processors for Sources.map(String, Predicate, Projection).

Uses of Projection in com.hazelcast.jet.pipeline

Methods in com.hazelcast.jet.pipeline with parameters of type Projection

Modifier and Type	Method	Description
static <T, K, V> BatchSource<T>	Sources.map(IMap<? extends K,? extends V> map, Predicate<K,V> predicate, Projection<? super Map.Entry<K,V>,? extends T> projection)	Returns a source that fetches entries from the given Hazelcast IMap.
static <T, K, V> BatchSource<T>	Sources.map(String mapName, Predicate<K,V> predicate, Projection<? super Map.Entry<K,V>,? extends T> projection)	Returns a source that fetches entries from a local Hazelcast IMap with the specified name.
<T_NEW> RemoteMapSourceBuilder<K,V,T_NEW>	RemoteMapSourceBuilder.projection(Projection<? super Map.Entry<K,V>,? extends T_NEW> projection)	Set the projection to apply at the source.
static <T, K, V> BatchSource<T>	Sources.remoteMap(String mapName, ClientConfig clientConfig, Predicate<K,V> predicate, Projection<? super Map.Entry<K,V>,? extends T> projection)	Returns a source that fetches entries from a remote Hazelcast IMap with the specified name in a remote cluster identified by the supplied ClientConfig.
static <T, K, V> BatchSource<T>	Sources.remoteMap(String mapName, DataConnectionRef dataConnectionRef, Predicate<K,V> predicate, Projection<? super Map.Entry<K,V>,? extends T> projection)	The same as the Sources.remoteMap(String, ClientConfig, Predicate, Projection) method.

Uses of Projection in com.hazelcast.map

Methods in com.hazelcast.map with parameters of type Projection

Modifier and Type	Method	Description
<R> Collection<R>	IMap.project(Projection<? super Map.Entry<K,V>,R> projection)	Applies the projection logic on all map entries and returns the result
<R> Collection<R>	IMap.project(Projection<? super Map.Entry<K,V>,R> projection, Predicate<K,V> predicate)	Applies the projection logic on map entries filtered with the Predicated and returns the result
