Nested Class Summary

Nested Classes

Modifier and Type	Class	Description
static class	AggregationOptions.Builder	Builder for creating AggregationOptions.
static class	AggregationOptions.OutputMode	Deprecated. There is no replacement for this. Applications can assume that the driver will use a cursor for server versions that support it (>= 2.6). The driver will ignore this as of MongoDB 3.6, which does not support inline results for the aggregate command.

Method Summary

Modifier and Type	Method	Description
static AggregationOptions.Builder	builder()	Creates a new Builder for AggregationOptions.
Boolean	getAllowDiskUse()	If true, this enables external sort capabilities, otherwise $sort produces an error if the operation consumes 10 percent or more of RAM.
Integer	getBatchSize()	The size of batches to use when iterating over results.
Boolean	getBypassDocumentValidation()	Gets whether to bypass document validation, or null if unspecified.
Collation	getCollation()	Returns the collation options
long	getMaxTime(TimeUnit timeUnit)	Gets the maximum execution time for the aggregation command.
AggregationOptions.OutputMode	getOutputMode()	Deprecated. There is no replacement for this. Applications can assume that the driver will use a cursor for server versions that support it (>= 2.6). The driver will ignore this as of MongoDB 3.6, which does not support inline results for the aggregate command.
