Method Detail

maxTime

public ListIndexesIterable<TResult> maxTime(long maxTime,
                                            java.util.concurrent.TimeUnit timeUnit)

Description copied from interface: ListIndexesIterable

Sets the maximum execution time on the server for this operation.

Specified by:

maxTime in interface ListIndexesIterable<TResult>

Parameters:

maxTime - the max time

timeUnit - the time unit, which may not be null

Returns:

this

batchSize

public ListIndexesIterable<TResult> batchSize(int batchSize)

Description copied from interface: ListIndexesIterable

Sets the number of documents to return per batch.

Specified by:

batchSize in interface ListIndexesIterable<TResult>

Specified by:

batchSize in interface MongoIterable<TResult>

Parameters:

batchSize - the batch size

Returns:

this

iterator

public MongoCursor<TResult> iterator()

Specified by:

iterator in interface MongoIterable<TResult>

Specified by:

iterator in interface java.lang.Iterable<TResult>

first

public TResult first()

Description copied from interface: MongoIterable

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

Specified by:

first in interface MongoIterable<TResult>

Returns:

T the first item or null.

map

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

Description copied from interface: MongoIterable

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

Specified by:

map in interface MongoIterable<TResult>

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 TResult> block)

Description copied from interface: MongoIterable

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 MongoIterable<TResult>

Parameters:

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

into

public <A extends java.util.Collection<? super TResult>> A into(A target)

Description copied from interface: MongoIterable

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

Specified by:

into in interface MongoIterable<TResult>

Type Parameters:

A - the collection type

Parameters:

target - the collection to insert into

Returns:

the target

execute

private MongoIterable<TResult> execute()

createListIndexesOperation
