Detailed Description

implements appender writing to an output stream via StreamWriter

Qore streams are not designed to accept input from multiple threads simultaneously, so writing must be serialized and processed in a dedicated thread

Member Function Documentation

Logger::LoggerAppenderStream::constructor ( *string  name,
LoggerLayout  layout,
StreamWriter  writer 
)

Creates the object.
