# Documentation: DTS.Common.ServiceLibrary
|
||
|
|
|
||
|
|
## 1. Purpose
|
||
|
|
This module implements a Windows Communication Foundation (WCF) service library defined within the `DTS.Common.ServiceLibrary` namespace. It provides a concrete implementation of the `IServiceLibrary` service contract, offering two basic operations: a simple data retrieval method and a data manipulation method using a data contract. Based on the inline comments (e.g., "Rename command," "TODO"), this module appears to be a boilerplate or template-generated code intended to serve as a starting point for service development.
|
||
|
|
|
||
|
|
## 2. Public Interface
|
||
|
|
|
||
|
|
### Class: `ServiceLibrary`
|
||
|
|
**Implements:** `IServiceLibrary`
|
||
|
|
**Location:** `ServiceLibrary.cs`
|
||
|
|
|
||
|
|
* **`string GetData(int value)`**
|
||
|
|
* Accepts an integer `value` and returns a formatted string: `"You entered: {value}"`.
|
||
|
|
* **`CompositeType GetDataUsingDataContract(CompositeType composite)`**
|
||
|
|
* Accepts an object of type `CompositeType`.
|
||
|
|
* **Behavior:**
|
||
|
|
* Throws `ArgumentNullException` if `composite` is `null`.
|
||
|
|
* If `composite.BoolValue` is `true`, appends the string `"Suffix"` to `composite.StringValue`.
|
||
|
|
* Returns the modified `composite` object.
|
||
|
|
|
||
|
|
### Interface: `IServiceLibrary`
|
||
|
|
**Attributes:** `[ServiceContract]`
|
||
|
|
**Location:** `IServiceLibrary.cs`
|
||
|
|
|
||
|
|
* **`[OperationContract] string GetData(int value)`**
|
||
|
|
* **`[OperationContract] CompositeType GetDataUsingDataContract(CompositeType composite)`**
|
||
|
|
|
||
|
|
### Class: `CompositeType`
|
||
|
|
**Attributes:** `[DataContract]`
|
||
|
|
**Location:** `IServiceLibrary.cs`
|
||
|
|
|
||
|
|
* **`bool BoolValue`**
|
||
|
|
* Attribute: `[DataMember]`
|
||
|
|
* Default Value: `true`
|
||
|
|
* Auto-implemented property backing field initialized to `true`.
|
||
|
|
* **`string StringValue`**
|
||
|
|
* Attribute: `[DataMember]`
|
||
|
|
* Default Value: `"Hello "`
|
||
|
|
* Auto-implemented property backing field initialized to `"Hello "`.
|
||
|
|
|
||
|
|
## 3. Invariants
|
||
|
|
* **Null Checking:** The method `GetDataUsingDataContract` explicitly guarantees that it will throw an `ArgumentNullException` if the input `composite` parameter is `null`.
|
||
|
|
* **State Mutation:** `GetDataUsingDataContract` modifies the state of the passed `composite` object in-place (specifically `StringValue`) rather than returning a new instance, provided `BoolValue` is `true`.
|
||
|
|
* **Serialization:** `CompositeType` is marked with `[DataContract]` and its properties with `[DataMember]`, implying it must be serializable by the WCF runtime for transport.
|
||
|
|
|
||
|
|
## 4. Dependencies
|
||
|
|
**Internal Dependencies:**
|
||
|
|
* `ServiceLibrary` depends on `IServiceLibrary` for the service contract definition.
|
||
|
|
* `ServiceLibrary` depends on `CompositeType` for data transfer operations.
|
||
|
|
|
||
|
|
**External Dependencies (System Assemblies):**
|
||
|
|
* `System.Runtime.Serialization`: Required for `DataContract`, `DataMember` attributes.
|
||
|
|
* `System.ServiceModel`: Required for `ServiceContract`, `OperationContract` attributes.
|
||
|
|
* `System`: Required for basic types (`string`, `int`, `ArgumentNullException`).
|
||
|
|
|
||
|
|
## 5. Gotchas
|
||
|
|
* **Boilerplate Code:** The source code contains default Visual Studio template comments (e.g., `// NOTE: You can use the "Rename" command...`, `// TODO: Add your service operations here`). This indicates the code may not contain production-specific business logic and has not been refactored to remove template artifacts.
|
||
|
|
* **Side Effect in `GetDataUsingDataContract`:** This method mutates the `StringValue` property of the input object. Developers consuming this API might expect a pure function that returns a new object or leaves the input unchanged. This mutation occurs if `BoolValue` is `true`.
|
||
|
|
* **Naming Collision:** The class `ServiceLibrary` shares the same name as the namespace `DTS.Common.ServiceLibrary`. While valid in C#, this can lead to confusion in resolution or documentation generation.
|
||
|
|
* **Legacy Exception Construction:** The `ArgumentNullException` is thrown using the legacy constructor overload `new ArgumentNullException("composite")` rather than `nameof(composite)`, suggesting the code was written for an older version of C# or generated by an older template.
