Detailed Description

StreamHandlerFactory is a LogHandlerFactory that constructs log handlers that write to stdout or stderr.

This is quite similar to FileHandlerFactory, but it always writes to an existing open file descriptor rather than opening a new file. This handler factory is separate from FileHandlerFactory primarily for safety reasons: FileHandlerFactory supports appending to arbitrary files via config parameters, while StreamHandlerFactory does not.

StringPiece folly::StreamHandlerFactory::getType ( ) const

inlineoverridevirtual

Get the type name of this LogHandlerFactory.

The type field in the LogHandlerConfig for all LogHandlers created by this factory should match the type of the LogHandlerFactory.

The type of a LogHandlerFactory should never change. The returned StringPiece should be valid for the lifetime of the LogHandlerFactory.
