Operations

interface MongoDBInterface {
  RequestResponse:
  connect (ConnectRequest)(ConnectResponse) throws MongoException ,
  find   (FindRequest)(FindResponse)   throws MongoException JsonParseException ,
  insert  (InsertRequest)(InsertResponse)   throws MongoException JsonParseException IndexDuplicate,
  update  (UpdateRequest)(UpdateResponse)   throws MongoException JsonParseException IndexDuplicate,
  delete  (DelRequest)(DeleteResponse)   throws MongoException JsonParseException ,
  aggregate (AggregateRequest)(AggregateResponse) throws MongoException JsonParseException,
  
}

connect

This operation allows your service to connect to the to your instance of MongoDB

type ConnectRequest:void{
 .host ?: string
 .dbname : string
 .uri?:string
 .port ?:int
 .timeZone:string
 .jsonStringDebug?:bool
 .logStreamDebug?:bool
 .username?:string
 .password?:string
}

    connect@mongodb( { host= "localhost" 
                       port=27017 
                       dbname= "test" 
                       username = "test" 
                       password="test" 
                       timeZone ="Europe/Berlin" } )(  )

insert

This operation inserts a new document into a specific collection

type InsertRequest:void{
 .collection: string
 .document:undefined
}

   insert@mongodb( {collection = "test" 
                    document.nodeA = "nodeA" 
                    document.nodeB = 10 } )(  )

find

This operation allows you to search for documents in a specific collection that match a specific filter

type FindRequest:void{
  .collection: string
  .filter?:undefined
  .projection?:undefined
  .sort?:undefined
  .limit?: int
  .skip?:int
}

    find@mongodb( {collection = "test"
                  filter = "{nodeB : { $eq : '$nodeB' } }"
                  filter.nodeB= 10
                  projection="{_id:0}" } )( pipelineRequest.data  )

in this example we see how to pass a dinamically a parameter to the filter jsonObject

filter = "{nodeB : { $eq : '$nodeB' } }"

the format to pass parameter is '$parameterName' the paramater value need to be injected by passing as child node of filter node

filter.nodeB= 10
