Detailed Description

Holds the public (to MooseApp) facing CapabilityRegistry for storing and checking capabilities.

A capability can refer to an optional library or optional functionality. Capabilities can either be registered as boolean values (present or not), an integer quantity (like the AD backing store size), a string (like the compiler used to build the executable), or a version number (numbers separated by dots, e.g. the petsc version).

Member Typedef Documentation

RegistryType

using Moose::internal::CapabilityRegistry::RegistryType = std::map<std::string, Capability, std::less<> >

inherited

Type for the registry.

Member Enumeration Documentation

CheckState

enum Moose::internal::CapabilityRegistry::CheckState

inherited

Return state for check.

We use a plain enum because we rely on implicit conversion to int. Capability checks are run in the test harness using the JSON dump exported from the executable using --show-capabilities. This static check does not take dynamic loading into account, as capabilities that would be registered after initializing the dynamically loaded application will not exist with --show-capabilities.

A requested capability that is not registered at all is considered in a "possible" state, as we cannot guarantee that it does or not exist with a dynamic application. If no dynamic application loading is used, the possible states can be considered certain states.

When the test harness Tester specification "dynamic_capabilities" is set to True, it will run the test unless the result of the check is CERTAIN_FAIL. In this case, the runtime check in the executable will terminate if the result is either CERTAIN_FAIL or POSSIBLE_FAIL.

augment()

void Moose::internal::Capabilities::augment	(	const nlohmann::json &	input,
		const AugmentPassKey
	)

Augment the capabilities with the given input capabilities.

This is used when loading additional capabilities at run time from the TestHarness and thus is only allowed to be used by the MooseApp.

check()

CapabilityRegistry::CheckResult Moose::internal::CapabilityRegistry::check ( std::string  requirements, const CapabilityRegistry::CheckOptions &  options = CapabilityRegistry::CheckOptions()  ) const

inherited

Checks if a set of requirements is satisified by the capabilities.

Parameters

requirements	The requirement string
options	Options to apply to the check

This method is exposed to Python within pycapabilities.Capabilities.check in python/pycapabilities/_pycapabilities.C. This external method is used significantly by the TestHarness to check capabilities for individual test specs.

Additionally, this method is used by the MooseApp command line option "--required-capabilities ...".

Requirements can use comparison operators (>,<,>=,<=,=!,=), where the name of the capability must always be on the left hand side. Comparisons can be performed on strings "compiler!=GCC" (which are case insensitive), integer numbers "ad_size>=50", and version numbers "petsc>3.8.0". The state of a boolean valued capability can be tested by just specifying the capability name "chaco". This check can be inverted using the ! operator as "!chaco".

The logic operators & and | can be used to chain multiple checks as "thermochimica & thermochimica>1.0". Parenthesis can be used to build complex logic expressions.

Get the singleton Capabilities.

Only accessible through MooseApp and AppFactory. Addition of capabilities should be done through the MooseApp::add[Bool,Int,String]capability() method.
