CoreRemoteMappingIterable

public CoreRemoteMappingIterable(CoreRemoteMongoIterable<U> iterable,
                                 Function<U,V> mapper)

Method Detail

iterator

@Nonnull
public CoreRemoteMongoCursor<V> iterator()

Specified by:

iterator in interface CoreRemoteMongoIterable<U>

Specified by:

iterator in interface Iterable<U>

first

@Nullable
public V first()

Description copied from interface: CoreRemoteMongoIterable

Helper to return the first item in the iterator or null.

Specified by:

first in interface CoreRemoteMongoIterable<U>

Returns:

T the first item or null.

forEach

public void forEach(Block<? super V> block)

Description copied from interface: CoreRemoteMongoIterable

Iterates over all documents in the view, applying the given block to each.

Similar to map but the function is fully encapsulated with no returned result.

Specified by:

forEach in interface CoreRemoteMongoIterable<U>

Parameters:

block - the block to apply to each document of type T.

into

public <A extends Collection<? super V>> A into(A target)

Description copied from interface: CoreRemoteMongoIterable

Iterates over all the documents, adding each to the given target.

Specified by:

into in interface CoreRemoteMongoIterable<U>

Type Parameters:

A - the collection type

Parameters:

target - the collection to insert into

Returns:

the target

map

public <W> CoreRemoteMongoIterable<W> map(Function<V,W> newMap)

Description copied from interface: CoreRemoteMongoIterable

Maps this iterable from the source document type to the target document type.

Specified by:

map in interface CoreRemoteMongoIterable<U>

Type Parameters:

W - the target document type

Parameters:

newMap - a function that maps from the source to the target document type

Returns:

an iterable which maps T to U
