DiagnosticsHandler Class

DiagnosticsHandler collects all diagnostics messages entered by any of the Write method and triggers a MessageEvent. However, it only issues the same message 100 timers, the statistics for that can be retrieved by WriteSkippedMessagesSummary

It is thread safe, i.e. it handles synchronization issues between potential several worker threads.

To connect a diagnostics object for "live" messages, connect the DiagnosticsHandler object directly to the Diagnostics object:

Copy

diagnostics.DiagnosticsEvent += diagnosticsHandler.Write;

To write all messages of a diagnostics object, call the WriteAllIssuesRecursive(IDiagnostics) method.

	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	NewMessage	Create directly a new message to be sent on
	Reset	Reset DiagnosticsHandler, clearing counters for error messages and any pending messages in the queue
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	Write	Print one item of a Diagnostics to listeners. Can be used to connect to DiagnosticsEvent of another Diagnostics object, to transfer any items to this class.
	WriteAllIssuesRecursive	Print hints, warnings, and erros of a Diagnostics to the listeners. Calls all children recursively.
	WriteSkippedMessagesSummary	Print a summary of hints, warnings, and erros that has been skipped.
