Sets or gets the default captureRejection value for all emitters.
This symbol shall be used to install a listener for only monitoring
events. Listeners installed using this symbol are called before the regular
'error' listeners are called.
Installing a listener using this symbol does not change the behavior once an
'error' event is emitted, therefore the process will still crash if no
'error' listener is installed.
Add a cursor flag to the cursor
The flag to set, must be one of following ['tailable', 'oplogReplay', 'noCursorTimeout', 'awaitData', 'partial' -.
The flag boolean value.
Allows disk use for blocking sort operations exceeding 100MB memory. (MongoDB 3.2 or higher)
Returns current buffered documents length
Returns a new uninitialized copy of this cursor, with options matching those that have been set on the current instance
Add a comment to the cursor query allowing for tracking the comment in the log.
The comment attached to this query.
Iterates over all the documents for this cursor using the iterator, callback pattern.
The iteration callback.
Set the limit for the cursor.
The limit for the cursor query.
Map all documents using the provided function If there is a transform set on the cursor, that will be called first and the result passed to this function's transform.
Set a maxAwaitTimeMS on a tailing cursor query to allow to customize the timeout value for the option awaitData (Only supported on MongoDB 3.2 or higher, ignored otherwise)
Number of milliseconds to wait before aborting the tailed query.
Set a maxTimeMS on the cursor query, allowing for hard timeout limits on queries (Only supported on MongoDB 2.6 or higher)
Number of milliseconds to wait before aborting the query.
Get the next available document from the cursor, returns null if no more documents are available.
Returns current buffered documents
Set the cursor returnKey. If set to true, modifies the cursor to only return the index field or fields for the results of the query, rather than documents. If set to true and the query does not use an index to perform the read operation, the returned documents will not contain any fields.
the returnKey value.
Rewind this cursor to its uninitialized state. Any options that are present on the cursor will remain in effect. Iterating this cursor will cause new queries to be sent to the server, even if the resultant data has already been retrieved by this cursor.
Modifies the output of a query by adding a field $recordId to matching documents. $recordId is the internal key which uniquely identifies a document in a collection.
The $showDiskLoc option has now been deprecated and replaced with the showRecordId field. $showDiskLoc will still be accepted for OP_QUERY stye find.
Set the skip for the cursor.
The skip for the cursor query.
Returns an array of documents. The caller is responsible for making sure that there is enough memory to store the results. Note that the array only contains partial results when this cursor had been previously accessed. In that case, cursor.rewind() can be used to reset the cursor.
Try to get the next available document from the cursor or
null if an empty batch is returned
Returns a list listener for a specific emitter event name.
