# LevelTriggers
|
||
|
|
|
||
|
|
## 1. Purpose
|
||
|
|
This module defines the XML serialization contract for serializing and deserializing a collection of level triggers in the DTS system. Specifically, `LevelTriggersXMLClass` serves as the root container object for a list of `LevelTriggerXMLClass` instances, enabling structured persistence (e.g., to/from XML files) of level-trigger configurations used in test setup workflows. It exists to bridge in-memory test setup data structures with a standardized XML representation, ensuring interoperability and configuration portability.
|
||
|
|
|
||
|
|
## 2. Public Interface
|
||
|
|
- **`LevelTriggersXMLClass`**
|
||
|
|
- **Property**: `public List<LevelTriggerXMLClass> LevelTriggers { get; set; }`
|
||
|
|
- **Behavior**: Holds the collection of level trigger definitions. When serialized using `XmlSerializer`, each item in this list will be serialized as an XML element named `<LevelTrigger>`, due to the `[XmlElement("LevelTrigger")]` attribute. The property is nullable by default (no explicit initialization in the class); callers must ensure it is instantiated (e.g., via constructor or assignment) before use to avoid `NullReferenceException` during serialization/deserialization.
|
||
|
|
|
||
|
|
## 3. Invariants
|
||
|
|
- The `LevelTriggers` property must be a non-null `List<LevelTriggerXMLClass>` before serialization or enumeration to prevent runtime exceptions.
|
||
|
|
- The XML element name for each list item is strictly `"LevelTrigger"` (case-sensitive), as enforced by the `[XmlElement("LevelTrigger")]` attribute.
|
||
|
|
- The class itself is a pure data container with no business logic; it relies entirely on `System.Xml.Serialization` for correct behavior.
|
||
|
|
- No validation is performed on the contents of `LevelTriggers` (e.g., no duplicate checks, no required fields enforced at this level).
|
||
|
|
|
||
|
|
## 4. Dependencies
|
||
|
|
- **Depends on**:
|
||
|
|
- `System.Xml.Serialization` (for `[XmlElement]` attribute and `XmlSerializer` usage)
|
||
|
|
- `DTS.Common.XMLUtils.LevelTriggerXMLClass` (referenced as the generic type argument in `List<LevelTriggerXMLClass>`)
|
||
|
|
- **Depended on by**:
|
||
|
|
- Presumably higher-level XML export/import utilities (e.g., classes responsible for serializing entire test setups) that consume or produce `LevelTriggersXMLClass` instances.
|
||
|
|
- The exact consumers are not visible in this file but would be in modules handling test setup persistence (e.g., classes in `TestSetupExportXML` or similar namespaces).
|
||
|
|
|
||
|
|
## 5. Gotchas
|
||
|
|
- **No default constructor or initialization**: The `LevelTriggers` property is not auto-initialized; it will be `null` unless explicitly set. Callers must instantiate it (e.g., `new LevelTriggersXMLClass { LevelTriggers = new List<LevelTriggerXMLClass>() }`) before adding items or serializing.
|
||
|
|
- **No validation or immutability**: The class provides no safeguards against null items in the list or inconsistent trigger states. Validation must occur at a higher layer.
|
||
|
|
- **Assumes `LevelTriggerXMLClass` is serializable**: If `LevelTriggerXMLClass` lacks proper XML serialization attributes (e.g., `[XmlRoot]`, public properties with getters/setters), deserialization may fail silently or produce incomplete data.
|
||
|
|
- **No versioning or schema awareness**: The class does not include version fields or schema validation logic; changes to `LevelTriggerXMLClass` may break backward compatibility without explicit handling elsewhere.
|
||
|
|
- **None identified from source alone** for behavioral quirks beyond the above—no comments, legacy attributes, or non-standard patterns are present.
