Method Summary

Modifier and Type	Method	Description
void	batchCursor(SingleResultCallback<AsyncBatchCursor<TResult>> callback)	Deprecated. Provide the underlying AsyncBatchCursor allowing fine grained control of the cursor.
MongoIterable<TResult>	batchSize(int batchSize)	Deprecated. Sets the number of documents to return per batch.
void	first(SingleResultCallback<TResult> callback)	Deprecated. Helper to return the first item in the iterator or null.
void	forEach(Block<? super TResult> block, SingleResultCallback<Void> callback)	Deprecated. Iterates over all documents in the view, applying the given block to each, and completing the returned future after all documents have been iterated, or an exception has occurred.
Integer	getBatchSize()	Deprecated. Gets the number of documents to return per batch or null if not set.
<A extends Collection<? super TResult>> void	into(A target, SingleResultCallback<A> callback)	Deprecated. Iterates over all the documents, adding each to the given target.
<U> MongoIterable<U>	map(Function<TResult,U> mapper)	Deprecated. Maps this iterable from the source document type to the target document type.

Method Detail

first

void first(SingleResultCallback<TResult> callback)

Deprecated.

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

Parameters:

callback - a callback that is passed the first item or null.

forEach

void forEach(Block<? super TResult> block,
             SingleResultCallback<Void> callback)

Deprecated.

Iterates over all documents in the view, applying the given block to each, and completing the returned future after all documents have been iterated, or an exception has occurred.

Parameters:

block - the block to apply to each document

callback - a callback that completed once the iteration has completed

into

<A extends Collection<? super TResult>> void into(A target,
                                                  SingleResultCallback<A> callback)

Deprecated.

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

Type Parameters:

A - the collection type

Parameters:

target - the collection to insert into

callback - a callback that will be passed the target containing all documents

map

<U> MongoIterable<U> map(Function<TResult,U> mapper)

Deprecated.

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

batchSize

MongoIterable<TResult> batchSize(int batchSize)

Deprecated.

Sets the number of documents to return per batch.

Parameters:

batchSize - the batch size

Returns:

this

batchCursor

void batchCursor(SingleResultCallback<AsyncBatchCursor<TResult>> callback)

Deprecated.

Provide the underlying AsyncBatchCursor allowing fine grained control of the cursor.

Parameters:

callback - a callback that will be passed the AsyncBatchCursor
