Méthode Description
__construct ( Builder $builder )
execute ( array $options = [] ) : Doctrine\MongoDB\Iterator Executes the aggregation pipeline
geoNear ( float | array | GeoJson\Geometry\Point $x, float $y = null ) : Doctrine\MongoDB\Aggregation\Stage\GeoNear Outputs documents in order of nearest to farthest from a specified point.
getExpression ( ) : array Assembles the aggregation stage
getPipeline ( ) : array Returns the assembled aggregation pipeline
group ( ) : Group Groups documents by some specified expression and outputs to the next stage a document for each distinct grouping.
indexStats ( ) : Doctrine\MongoDB\Aggregation\Stage\IndexStats Returns statistics regarding the use of each index for the collection.
limit ( integer $limit ) : Doctrine\MongoDB\Aggregation\Stage\Limit Limits the number of documents passed to the next stage in the pipeline.
lookup ( string $from ) : Doctrine\MongoDB\Aggregation\Stage\Lookup Performs a left outer join to an unsharded collection in the same database to filter in documents from the “joined” collection for processing.
match ( ) : Match Filters the documents to pass only the documents that match the specified condition(s) to the next pipeline stage.
out ( string $collection ) : Out Takes the documents returned by the aggregation pipeline and writes them to a specified collection. This must be the last stage in the pipeline.
project ( ) : Project Passes along the documents with only the specified fields to the next stage in the pipeline. The specified fields can be existing fields from the input documents or newly computed fields.
redact ( ) : Doctrine\MongoDB\Aggregation\Stage\Redact Restricts the contents of the documents based on information stored in the documents themselves.
sample ( integer $size ) : Doctrine\MongoDB\Aggregation\Stage\Sample Randomly selects the specified number of documents from its input.
skip ( integer $skip ) : Doctrine\MongoDB\Aggregation\Stage\Skip Skips over the specified number of documents that pass into the stage and passes the remaining documents to the next stage in the pipeline.
sort ( array | string $fieldName, integer | string $order = null ) : Doctrine\MongoDB\Aggregation\Stage\Sort Sorts all input documents and returns them to the pipeline in sorted order.
unwind ( string $fieldName ) : Doctrine\MongoDB\Aggregation\Stage\Unwind Deconstructs an array field from the input documents to output a document for each element. Each output document is the input document with the value of the array field replaced by the element.
