Interface SimpleMap<T>

All Superinterfaces:

MapSerializable, MapWriter, NavigableObject

All Known Implementing Classes:

BaseCloudSolrClient.RouteResponse, CloudSolrClient.RouteResponse, LinkedSimpleHashMap, NamedList, SimpleOrderedMap, WrappedSimpleMap

public interface SimpleMap<T>
extends MapWriter

A simplified read-only key-value structure. It is designed to support large datasets without consuming lot of memory The objective is to provide implementations that are cheap and memory efficient to implement and consume. The keys are always CharSequence objects, The values can be of any type

Method Detail

get

T get(String key)

get a value by key. If not present , null is returned

get

default T get(String key,
              T def)

forEachEntry

void forEachEntry(BiConsumer<String,? super T> fun)

Navigate through all keys and values

forEachKey

default void forEachKey(Consumer<String> fun)

iterate through all keys The default impl is suboptimal. Proper implementations must do it more efficiently

size

int size()

abortableForEachKey

default void abortableForEachKey(Function<String,Boolean> fun)

iterate through all keys but abort in between if required The default impl is suboptimal. Proper implementations must do it more efficiently

Parameters:

fun - Consume each key and return a boolean to signal whether to proceed or not. If true , continue. If false stop

abortableForEach

default void abortableForEach(BiFunction<String,? super T,Boolean> fun)

Navigate through all key-values but abort in between if required. The default impl is suboptimal. Proper implementations must do it more efficiently

Parameters:

fun - Consume each entry and return a boolean to signal whether to proceed or not. If true, continue, if false stop

writeMap

default void writeMap(MapWriter.EntryWriter ew)
               throws IOException

Specified by:

writeMap in interface MapWriter

Throws:

IOException
