Method Detail

iterator

@Nonnull
public CoreRemoteMongoCursor<ResultT> iterator()

Specified by:

iterator in interface CoreRemoteMongoIterable<OpsT>

Specified by:

iterator in interface Iterable<OpsT>

first

@Nullable
public ResultT first()

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

Specified by:

first in interface CoreRemoteMongoIterable<OpsT>

Returns:

T the first item or null.

map

public <U> CoreRemoteMongoIterable<U> map(Function<ResultT,U> mapper)

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

Specified by:

map in interface CoreRemoteMongoIterable<OpsT>

Type Parameters:

U - the target document type

Parameters:

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

Returns:

an iterable which maps T to U

forEach

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

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<OpsT>

Parameters:

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

into

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

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

Specified by:

into in interface CoreRemoteMongoIterable<OpsT>

Type Parameters:

A - the collection type

Parameters:

target - the collection to insert into

Returns:

the target
