📄️ Blob
The Blob class lets you create and manipulate blob objects (4D.Blob).
📄️ Class
When a user class is defined in the project, it is loaded in the QodlyScript environment. A class is an object itself, of "Class" class, which has properties and a function.
📄️ Collection
The Collection class manages collection type elements.
📄️ CryptoKey
The CryptoKey class in QodlyScript encapsulates an asymmetric encryption key pair.
📄️ DataClass
A DataClass provides an object interface to a database table. All dataclasses in a Qodly application are available as a property of the ds datastore.
📄️ DataStore
A Datastore is the interface object provided by ORDA to reference and access a database. A Datastore object is returned by the ds command (a shortcut to the main datastore) or the openDatastore command.
📄️ Email
Creating, sending or receiving emails in Qodly is done by handling an Email object.
📄️ Endpoints
Overview
📄️ Entity
An entity is an instance of a Dataclass, like a record of the table matching the dataclass in its associated datastore. It contains the same attributes as the dataclass as well as the data values and specific properties and functions.
📄️ EntitySelection
An entity selection is an object containing one or more reference(s) to entities belonging to the same Dataclass. An entity selection can contain 0, 1 or X entities from the dataclass -- where X can represent the total number of entities contained in the dataclass.
📄️ File
File objects are created with the file command. They contain references to disk files that may or may not actually exist on disk. For example, when you execute the file command to create a new file, a valid file object is created but nothing is actually stored on disk until you call the file.create() function.
📄️ FileHandle
The FileHandle class has functions that allow you to sequentially read from or append contents to an opened file object. A file handle can access any part of a document.
📄️ Folder
Folder objects are created with the folder command. They contain references to folders that may or may not actually exist on disk. For example, when you execute the folder command to create a new folder, a valid folder object is created but nothing is actually stored on disk until you call the folder.create() function.
📄️ Function
A 4D.Function object contains a piece of code that can be executed from an object, either using the () operator, or using the apply() and call() functions. QodlyScript proposes three kinds of Function objects:
📄️ HTTPRequest
The HTTPRequest class allows you to handle HTTPRequest objects that can be used to configure and send requests to an HTTP server, as well as to process the HTTP server responses.
📄️ IMAPTransporter
The IMAPTransporter class allows you to retrieve messages from an IMAP email server.
📄️ IncomingMessage
The 4D.IncomingMessage class allows you to handle the object received by a custom HTTP request handler. HTTP requests and their properties are automatically received as an instance of the 4D.IncomingMessage class. Parameters given directly in the request with GET verb are handled by the .urlQuery property, while parameters passed in the body of the request are available through functions such as .getBlob() or getText().
📄️ MailAttachment
Attachment objects allow referencing files within a Email object.
📄️ OutgoingMessage
The 4D.OutgoingMessage class allows you to build messages to be returned by your application functions in response to REST requests. If the response is of type 4D.OutgoingMessage, the REST server does not return an object but the object instance of the OutgoingMessage class.
📄️ POP3Transporter
The POP3Transporter class allows you to retrieve messages from a POP3 email server.
📄️ QodlyEvents
Overview
📄️ Session
Session objects are returned by the Session command. The Session object is automatically created and maintained by the Qodly web server to control the session of a web client (e.g. a browser). This object provides the web developer with an interface to the user session, allowing to manage privileges, store contextual data, share information between processes, and launch session-related preemptive processes.
📄️ Signal
Signals are tools provided by the QodlyScript language to manage interactions and avoid conflicts between worker processes in a multiprocess application. Signals allow you to make sure one or more process(es) will wait for a specific task to be completed before continuing execution. Any process can wait and/or release a signal.
📄️ SMTPTransporter
The SMTPTransporter class allows you to configure SMTP connections and send emails.
📄️ SystemWorker
System workers allow the QodlyScript code to call any external process on the server machine. System workers are called asynchronously. By using callbacks, Qodly makes it possible to communicate both ways.
📄️ TCPConnection
The TCPConnection class allows you to manage Transmission Control Protocol (TCP) client connections to a server, enabling you to send and receive data, and handle connection lifecycle events using callbacks.
📄️ TCPEvent
The TCPEvent class provides information about events occurring during the lifecycle of a TCP connection. It is generated when a TCPConnection is opened and is typically utilized in callbacks such as onConnection, onData, onError, and others.
📄️ Users
Overview
📄️ WebForm
The 4D.WebForm class object provides an interface that allows you to handle your Page components. 4D.WebForm objects are instantiated with the webForm command.
📄️ WebFormItem
The 4D.WebFormItem class allows you to handle the behavior of your webform components.
📄️ ZIPArchive
A QodlyScript ZIP archive is a File or folder object containing one or more files or folders, which are compressed to be smaller than their original size. These archives are created with a ".zip" extension and can be used to save space or transfer files via mediums which may have size limitations (e.g., email or network).
📄️ ZIPFile
The following properties and functions from the File class are available to ZIPFile objects:
📄️ ZIPFolder
The following properties and functions from the Folder class are available to ZIPFolder objects:
