Member Function Documentation

virtual void activateOptions (  log4cxx::helpers::Pool &  p  )  [pure virtual]
 

Activate the options that were previously set with calls to option setters.

This allows to defer activiation of the options until all options have been set. This is required for components which have related options that remain ambigous until all are set.

For example, the FileAppender has the File and Append options both of which are ambigous until the other is also set.

virtual void setOption (  const LogString &  option,
const LogString &  value
)  [pure virtual]
 

Set option to value.
