protected:
virtual bool PreAppendCheck()

abstract PreAppendCheck : unit -> bool 
override PreAppendCheck : unit -> bool 

Return Value

This method is called by [M:DoAppend(LoggingEvent)] before the call to the abstract [M:Append(LoggingEvent)] method.

This method can be overridden in a subclass to extend the checks made before the event is passed to the [M:Append(LoggingEvent)] method.

A subclass should ensure that they delegate this call to this base class if it is overridden.
