Detailed Description

Container class to hold "global" NOX objects.

GlobalData is a container class that holds ref-count pointers to "global" objects, i.e., objects that nearly every NOX object will need access to. By putting them all in one container class, the container class can be stored in each NOX object, and if a new global object is needed, it can be added here without modifying the rest of the code. This is an alternative to true global or static objects which are not safe in many contexts (threading). In particular, this approach allows multiple NOX "invocations" to be in memory at the same time.

Teuchos::RCP< Teuchos::ParameterList > NOX::GlobalData::getNoxParameterList

(

)

const

Returns the top-level nox parameter list input by the user.

This list is kept in global data so that any sublists of the main parameters list that objects may keep a refernece to is still valid. The line searches and directions usually store data in an output sublist for the users to query. These sublists are NOT wrapped in reference counted smart pointers, so if the base list is deleted, the references to the sublist will no longer be valid. To remedy this, any object that stores a reference to a sublist should also store the global data object.

void NOX::GlobalData::initialize

(

const Teuchos::RCP< Teuchos::ParameterList > &

noxParams

)

Initiialize the global data from a top level (validated) nox parameter list.
