Class ValidationErrorMessage
Class name: ValidationErrorMessage
Namespace: Greenrain.Connect
Access modifier: Public
Description: This class contains error message details.
Public members: refer to the table below.
Member Name | Data Type | Default Value | Description |
|---|---|---|---|
Title | string | null | Title of the error message. For example, it can be a transaction name that can be later shown in the errors report. |
FileName | string | null | E-claim transaction file name, if available. |
ErrorType | ErrorTypeEnum.None | Error type. | |
ErrorDescription | string | null | Error message. |

AdditionalReference | string | null | Additional reference about the error, if available. |
Class GreenrainDdb
Class name: GreenrainDbc
Access modifier: Public
Description: This is the main class to run all available Drugs Database Checks.
Performance consideration: The class uses Drugs Database Checks edits that may consume a significant amount of memory (refer to Memory Consumption). Also, it might take a few seconds longer for the very first Drug Database check as the class loads all the edits to the memory during the first call. Therefore, it is important to consider the following to avoid a performance downgrade:
Create an instance of GreenrainDdb class only once when your application starts.
As one of the options, you might consider using singleton in your application.
Methods of the GreenrainDdb class may be called by different threads within the same process.
If you will create the instance of GreenrainDbc class just before you run the Drug Database check, this might slow down your application because it will load all the edits into the memory every time.
For example: if you get 1,000 claims to validate, you can use the following logic:
Create the instance of GreenrainDdb class when your app starts.
Create 10 threads to process 100 claims each.
Every thread can safely access the instance of GreenrainDdb class and validate their claims.
Public members: None.
Public methods: refer to the sections below.
Constructor
Access modifier: Public
Description: This is the class constructor.
Syntax
public GreenrainDbc(ILicenseManager licenseManager = null, IDdbSettings DdbSettings = null)
Parameters
Parameter | Data Type | Default Value | Description |
|---|---|---|---|
licenseManager | ILicenseManager | null | LicenseManager class. If the parameter is null, the class will use license key found in the Settings. |
DdbSettings | IDdbSettings | null | If this parameter is null, then the constructor uses the current Greenrain Drugs Database settings saved on the system. Otherwise, API uses the settings specified in the passed in DdbSettings class. Therefore, the constructor can be called with any settings combination required by the caller, even if it is different from the current system settings. |
Return Value
None.
Exceptions
None.
RunDdb Method

RunClaimSubmissionChecks Method
NOTE: this method is re-design at the moment. It will be released in one of the nearest updates during the summer 2022.
Access modifier: Public
Description
The method performs the following logic:
Parse the passed in Claim.Submission XML transaction.
Calculate patient age using Emirates ID Number. The assumption is made that patient's birth date is January 1.
If Emirates ID Number has the default value, then the patient's age is set to unknown. In this case, all age-related checks are disabled.
Patient gender is not available in Claim.Submission transactions, therefore, gender-related checks are disabled.
Call RunDdb Method if the claim has at least one drug code.
Only principal and secondary diagnoses are used for every claim. Other diagnosis types are ignored.
Syntax
public ValidationResult GreenrainDdb.RunClaimSubmissionChecks(byte[] xmlClaimSubmissionTransaction, string fileName);
Parameters
Parameter | Data Type | Default Value | Description |
|---|---|---|---|
xmlClaimSubmissionTransaction | byte[] | null | Content of XML file with Claim.Submission transaction. |
Return Value
The method returns a list of all found errors. A null value is returned if no alert is found.
Exceptions
Possible exceptions are described in the Exceptions section.
Exceptions
All API methods may raise exceptions described in the table below. The following rules are applied:
An exception is returned as Class ValidationResult.
ValidationResult.Code = value of the exception code.
ValidationResult.Description = value of the error message.
