public interface MongoIterable<TResult>
extends Iterable<TResult>
The MongoIterable is the results from an operation, such as a query.
Since:
cursor
MongoCursor<TResult> cursor()
Returns a cursor used for iterating over elements of type
TResult
. The cursor is primarily used for change streams.
Returns:
a cursor
Since:
<U> MongoIterable<U> map(Function<TResult,U> mapper)
Maps this iterable from the source document type to the target document type.
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
void forEach(
Block
<? super
TResult
> block)
Deprecated.
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.
block
- the block to apply to each document of type T.
<A extends Collection<? super TResult>> A into(A target)
Iterates over all the documents, adding each to the given target.
Type Parameters:
A
- the collection type
Parameters:
target
- the collection to insert into
Returns:
the target
batchSize
MongoIterable<TResult> batchSize(int batchSize)

Parameters:
batchSize
- the batch size
Returns:
-
MongoDB documentation
-
Batch Size
