as(objectName)
Extends CortexObject and returns a class with a constructor name matching objectName.
Arguments
objectName (String)
Returns
ClassJavaScript
1
const Nums = CortexObject.as('c_num');
2
const _id = Nums.insertOne({c_val: [1, 2, 3]}).execute();

from(context)
Returns an instance of a CortexObject based on the passed in context argument, which should have at least _id and object properties.
Arguments
context (Object)
Returns
CortexObject instance
aggregate(pipeline=[])
Returns an aggregation cursor based on the optional passed in pipeline argument. The pipeline must be in the form of an array and named aggregation steps ([{$match: {...}}, {$project: {...}}, ...]). A pipeline can also be built later using aggregation cursor chaining.
Arguments
pipeline (Object[])
Returns
​AggregationCursor​
count(match)
Returns a count of matching documents of the current CortexObject.
Arguments
match (Object) Optional match filter document.
Returns
Number
deleteOne(match)
Returns a delete operation based on the passed in match filter.
Arguments
match (Object) Optional match filter document.
Returns
(DeleteOperation)
find(match)
Returns a cursor based on the passed in match filter.
Arguments
match (Object) Match filter document.
Returns
​QueryCursor​
insertOne(doc)
Returns an insert operation.
Arguments
doc (Object) The document to insert.
Returns
​InsertOperation​
setOwner(id, to)
Transfers ownership of a context object to another account.
Arguments
id (ObjectID) The identifier of the instance to update.
to (ObjectID|String) The identifier or email of the new owner account.
Returns
Boolean true is modified or false if already owned by to.
setOwner is a low-level operation and does not implement any access controls, though an Audit log record is produced.
updateOne(match, doc)
Returns an update operation based on the passed in match filter.
$set and $push operations support updating existing document array elements by including their identifiers (e.g. push 2 items into c_arr of a specific document in the c_docs document array: { $push: {c_docs: {_id: '599284e01c9e955ff7526793', c_arr: [1, 2] }}}).
$unset operations can remove properties buried in specific documents
Arguments
match (Object) Optional match filter document.
doc (Object) An object containing the changes to effect. Update supports $set, $push, $unset and $remove.
$set Contains properties to update. (e.g. {$set: {name: {first: 'Auric', last: 'Goldfinger'}}})
$push Contains items to push into arrays and document arrays (e.g. {$push: {c_names: ['Jill Masterson']}})
$unset Unset one or more deletable properties (e.g. {$unset: {'c_doc.59928b74341a65ef3f03842b.c_deletable': 1, c_remove_me: 1}}).
$remove Removes elements from arrays, by full path (e.g. remove 2 documents from c_doc_array by identifier and all 1 and 2 values from c_num_arr in the c_doc_array document with an identifier of 59928b74341a65ef3f03842b: $remove: {'c_doc_array': ['59928aed341a65ef3f03836a', '59928af9341a65ef3f038380'], 'c_doc_array.59928b74341a65ef3f03842b.c_num_arr': [1,2] })
Returns
