Methods

Filter Extension

Extension method from System.Collections.Concurrent.SimpleMessageBus_ConcurrentDictionaryExtensions

Filters the metadata ConcurrentDictionary`2 to exclude keys ending with “-Status” or “-Timestamp”.

Syntax

public static System.Collections.Concurrent.ConcurrentDictionary<string, object> Filter(System.Collections.Concurrent.ConcurrentDictionary<string, object> metadata)

Parameters

Name	Type	Description
metadata	System.Collections.Concurrent.ConcurrentDictionary<string, object>	The metadata dictionary to filter.

Returns

Type: System.Collections.Concurrent.ConcurrentDictionary<string, object> A new concurrent dictionary containing only the non-status entries.

Remarks

This method helps filter out handler execution metadata when copying metadata between events, ensuring that the execution status of one event doesn’t affect another.

FilterAndCombine Extension

Extension method from System.Collections.Concurrent.SimpleMessageBus_ConcurrentDictionaryExtensions

Filters the metadata dictionary to exclude keys ending with “-Status” and combines it with the payload dictionary.

Syntax

public static System.Collections.Generic.Dictionary<string, object> FilterAndCombine(System.Collections.Concurrent.ConcurrentDictionary<string, object> metadata, System.Collections.Generic.Dictionary<string, object> payload)

Parameters

Name	Type	Description
metadata	System.Collections.Concurrent.ConcurrentDictionary<string, object>	The metadata dictionary to filter and combine.
payload	System.Collections.Generic.Dictionary<string, object>	The payload dictionary to combine with the filtered metadata.

Returns

Type: System.Collections.Generic.Dictionary<string, object> A new dictionary containing the combined entries from the payload and filtered metadata.

Remarks

This method helps filter out handler execution status from the metadata when constructing new messages or passing metadata between events in a processing chain.
