Constructor Detail

ListIndexesOperation

public ListIndexesOperation(MongoNamespace namespace,
                            Decoder<T> decoder)

Construct a new instance.

Parameters:

namespace - the database and collection namespace for the operation.

decoder - the decoder for the result documents.

Method Detail

getBatchSize

public java.lang.Integer getBatchSize()

Gets the number of documents to return per batch.

Returns:

the batch size

batchSize

public ListIndexesOperation<T> batchSize(int batchSize)

Sets the number of documents to return per batch.

Parameters:

batchSize - the batch size

Returns:

this

getMaxTime

public long getMaxTime(java.util.concurrent.TimeUnit timeUnit)

Gets the maximum execution time on the server for this operation. The default is 0, which places no limit on the execution time.

Parameters:

timeUnit - the time unit to return the result in

Returns:

the maximum execution time in the given time unit

maxTime

public ListIndexesOperation<T> maxTime(long maxTime,
                                       java.util.concurrent.TimeUnit timeUnit)

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

Parameters:

maxTime - the max time

timeUnit - the time unit, which may not be null

Returns:

this

execute

public BatchCursor<T> execute(ReadBinding binding)

Description copied from interface: ReadOperation

General execute which can return anything of type T

Specified by:

executeAsync

public void executeAsync(AsyncReadBinding binding,
                         SingleResultCallback<AsyncBatchCursor<T>> callback)

Description copied from interface: AsyncReadOperation

General execute which can return anything of type T

Specified by:

executeAsync in interface AsyncReadOperation<AsyncBatchCursor<T>>

Parameters:

binding - the binding to execute in the context of

callback - the callback to be called when the operation has been executed
