CargoReader Class

Properties   Methods   Events   Config Settings   Errors  

The CargoReader class is optimized for Cargo-IMP documents, providing a simple way to parse Cargo-IMP documents.

Syntax

ipworksedi.cargoreader()

Remarks

The class allows you to parse a Cargo-IMP message. Below are example steps:

  1. First, use LoadSchema to load a schema file into the class. (Only necessary when preserving document structure).
  2. Open a Cargo-IMP message or stream by setting input via InputFile or InputData.
  3. Call the Parse method to parse the message.
  4. When parsing is complete, you can retrieve the parsed values from the Values collection.

During parsing, the class performs basic validation of the incoming document. If validation fails, a warning is generated (fired as an event).

Schemas are written in JSON format: { "name": "FSU", "desc": "FSU MESSAGE", "children": { "1": { "desc": "Standard Message Identification", "children": { "1.1": { "desc": "Standard Message Identifier", "value": "FSU" }, "1.2": { "value": "/" }, "1.3": { "desc": "Message Type Version Number", "format": "n[...3]" }, "1.4": { "value": "\r\n" } } }, "2": { ... For example schemas and questions, please contact support@nsoftware.com.

CargoReader.Errors Property

A collection of errors that occurred when parsing the Cargo-IMP messages.

Syntax

getErrors(): CargoErrorList;

Default Value

Remarks

This property is populated with error information. After calling Parse, check this property to determine if any errors occurred while parsing the message. If there are any errors present, the Values collection will likely be incorrect.

This property is read-only and not available at design time.

Please refer to the CargoError type for a complete list of fields.

CargoReader.InputData Property

The data to parse.

Syntax

getInputData(): string;
setInputData(inputData: string): void;

Default Value

""

Remarks

This property specifies the data to be parsed.

Input Properties

The class will determine the source of the input based on which properties are set.

The order in which the input properties are checked is as follows:

When a valid source is found the search stops.

CargoReader.InputFile Property

The file to parse.

Syntax

getInputFile(): string;
setInputFile(inputFile: string): void;

Default Value

""

Remarks

This property specifies the file to be processed. Set this property to the full or relative path to the file which will be processed.

Input Properties

The class will determine the source of the input based on which properties are set.

The order in which the input properties are checked is as follows:

When a valid source is found the search stops.

This property is not available at design time.

CargoReader.Values Property

Collection of values after parsing the Cargo-Imp messages.

Syntax

getValues(): CargoValueList;

Default Value

Remarks

This property will be populated with the values from the Cargo-IMP message after parsing is complete.

This property is read-only and not available at design time.

Please refer to the CargoValue type for a complete list of fields.

CargoReader.config Method

Sets or retrieves a configuration setting.

Syntax

async cargoreader.config(configurationString : string): Promise<string>

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

CargoReader.loadSchema Method

Loads a schema file describing a Message type.

Syntax

async cargoreader.loadSchema(fileName : string): Promise<void>

Remarks

This method parses the File and loads it into an internal schema list.

If the schema file does not exist or cannot be parsed as an Cargo-IMP schema, the class .

Schemas are written in JSON format: { "name": "FSU", "desc": "FSU MESSAGE", "children": { "1": { "desc": "Standard Message Identification", "children": { "1.1": { "desc": "Standard Message Identifier", "value": "FSU" }, "1.2": { "value": "/" }, "1.3": { "desc": "Message Type Version Number", "format": "n[...3]" }, "1.4": { "value": "\r\n" } } }, "2": { ... For example schemas and questions, please contact support@nsoftware.com.

CargoReader.parse Method

Parse the specified input data.

Syntax

async cargoreader.parse(): Promise<void>

Remarks

This method parses the input data specified by InputFile or InputData.

Input Properties

The class will determine the source of the input based on which properties are set.

The order in which the input properties are checked is as follows:

When a valid source is found the search stops.

CargoReader.reset Method

Resets the class.

Syntax

async cargoreader.reset(): Promise<void>

Remarks

When called, the class initializes itself to its default state.

CargoReader.Error Event

Information about errors during data delivery.

Syntax

cargoreader.on('Error', listener: (e: {readonly errorCode: number, readonly description: string}) => void )

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the class .

The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

CargoReader.ResolveSchema Event

Fires whenever a new Cargo-Imp message is encountered and no schema is found for it.

Syntax

cargoreader.on('ResolveSchema', listener: (e: {readonly messageIdentifier: string, readonly version: string}) => void )

Remarks

The ResolveSchema event will fire when a the class encounters a new Cargo-IMP message, but it finds no schema corresponding to it already loaded.

MessageIdentifier contains the message type, such as "FWB" or "FSU".

Version contains the version of the schema used by the message.

When processing this event, the caller can use LoadSchema() to load a new schema into the class that can be used to parse the transaction.

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a class is using. It will return the following information:

  • Product: The product the license is for.
  • Product Key: The key the license was generated from.
  • License Source: Where the license was found (e.g., RuntimeLicense, License File).
  • License Type: The type of license installed (e.g., Royalty Free, Single Server).
  • Last Valid Build: The last valid build number for which the license will work.
MaskSensitive:   Whether sensitive data is masked in log messages.

In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to true to mask sensitive data. The default is true.

This setting only works on these classes: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

UseInternalSecurityAPI:   Whether or not to use the system security libraries or an internal implementation.

When set to false, the class will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this configuration setting to true tells the class to use the internal implementation instead of using the system security libraries.

This setting is set to false by default on all platforms.
