# SliceRaw
|
||
|
|
|
||
|
|
1. **Purpose**
|
||
|
|
This file defines a partial class `PersistentChannel` within the `DatabaseExport.File` namespace, intended to represent a channel whose state changes are immediately persisted to an associated channel file. Based on the summary comment and the commented-out interface implementations (`ExceptionalList<short>`, `ILargeDataAware`, `IChannelHeader`, `IDisposable`), the class is designed to serve as a live, file-backed abstraction over channel data—likely used for exporting or interfacing with legacy database versions (specifically Version 57, per the parent folder path). Its role is to provide a managed, in-memory view of persistent channel data with direct file synchronization semantics.
|
||
|
|
|
||
|
|
2. **Public Interface**
|
||
|
|
No public members (methods, properties, or events) are defined in this source file. The class `PersistentChannel` is declared as `public partial class`, but its body is empty in this file. All public interface members (if any) must be defined in other partial definitions of `PersistentChannel` (e.g., in sibling `.cs` files in the same project), which are not provided here.
|
||
|
|
|
||
|
|
3. **Invariants**
|
||
|
|
No invariants are explicitly stated or inferable from this file alone. However, based on the summary comment, the following is implied:
|
||
|
|
- Any modification to an instance of `PersistentChannel` must be immediately reflected in the underlying channel file on disk.
|
||
|
|
- The class likely maintains a file handle or stream to ensure persistence semantics (though not confirmed here).
|
||
|
|
Since the class declaration includes commented-out interface implementations, it is probable that certain interface contracts (e.g., `IDisposable` for resource cleanup, `IChannelHeader` for metadata access) were intended or previously used, but their enforcement or implementation details are not present in this file.
|
||
|
|
|
||
|
|
4. **Dependencies**
|
||
|
|
- **Internal**: Depends on the `DatabaseExport` namespace and the `File` partial class (defined elsewhere, likely in `SliceRaw.File.cs` or similar).
|
||
|
|
- **External**: No explicit external dependencies (e.g., no `using` directives) appear in this file. However, the commented-out interfaces (`ExceptionalList<short>`, `ILargeDataAware`, `IChannelHeader`, `IDisposable`) suggest that either:
|
||
|
|
- These interfaces are defined elsewhere in the same codebase (and their implementations reside in other partial files), or
|
||
|
|
- They were part of an earlier design and are now obsolete or deferred.
|
||
|
|
- **Consumers**: Likely consumed by other modules in the `DatabaseExport` namespace, particularly those handling Version 57 database export workflows (e.g., serialization, migration, or export logic in `Version57` folder).
|
||
|
|
|
||
|
|
5. **Gotchas**
|
||
|
|
- **Partial Class Ambiguity**: This file contributes only to a partial class definition; the full behavior of `PersistentChannel` cannot be understood without inspecting other partial definitions.
|
||
|
|
- **Commented-Out Interfaces**: The presence of commented-out interface implementations (`ExceptionalList<short>`, `ILargeDataAware`, `IChannelHeader`, `IDisposable`) may indicate incomplete refactoring, legacy design artifacts, or pending work. Developers should not assume these interfaces are implemented or enforced in this file.
|
||
|
|
- **No Implementation Visible**: The absence of any method/property definitions in this file means no behavior (e.g., read/write logic, persistence triggers, disposal semantics) can be verified here—critical functionality may reside elsewhere.
|
||
|
|
- **No Documentation on File Binding**: The phrase “immediately manifest in the associated channel file” is not elaborated; the mechanism (e.g., file path, locking strategy, flush behavior) is not specified in this source.
