|

//
|

// Composes and creates config objects.
|

|
|
// This interface is implemented by config providers.
|
|
// Classes implementing IConfigSectionHandler define the rules for cooking
|
|
// XML config into usable objects. The cooked objects
|
|
// can be of arbitrary type.
|
|
//
|
|
// Configuration is composable (e.g., config in a child
|
|
// directory is layered over config in a parent directory),
|
|
// so, IConfigSectionHandler is supplied with the parent config
|
|
// as well as any number of XML fragments.

|

// @param context reserved, in ASP.NET used to convey virtual path of config being evaluated
|
|
// @param section the xml node rooted at the section to handle
|
|
// @returns a new config object
|
|
//
|
|
// The function is responsible for inspecting "section", "context",
|
|
// and "parent", and creating a config object.
|
|
//
|
|
// Note that "parent" is guaranteed to be an object that
|
|
// was returned from a Create call on the same IConfigSectionHandler
|
|
// implementation. (E.g., if Create returns a Hashtable,
|
|
// then "parent" is always a Hashtable if it's non-null.)
|
|
//
|
|
// Returned objects must be immutable. In particular,
|
|
// it's important that the "parent" object being passed
|
|
// in is not altered: if a modification must be made,
|
|
// then it must be cloned before it is modified.
