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

NameTypeDescription
metadataSystem.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

NameTypeDescription
metadataSystem.Collections.Concurrent.ConcurrentDictionary<string, object>The metadata dictionary to filter and combine.
payloadSystem.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.
