Member Function Documentation

◆ getAPIVersion()

template<class Base >

virtual unsigned long CppAD::cg::FunctorModelLibrary< Base >::getAPIVersion ( )

inlinevirtualinherited

Provides the API version used to create the model library.

Returns: the API version

Definition at line 89 of file functor_model_library.hpp.

◆ getModelNames()

template<class Base >

std::set<std::string> CppAD::cg::FunctorModelLibrary< Base >::getModelNames ( )

inlineoverridevirtualinherited

Provides the model names in the dynamic library.

Returns: the model names

Implements CppAD::cg::ModelLibrary< Base >.

Definition at line 66 of file functor_model_library.hpp.

◆ getThreadNumber()

template<class Base >

unsigned int CppAD::cg::FunctorModelLibrary< Base >::getThreadNumber ( ) const

inlineoverridevirtualinherited

Provides the maximum number of threads used to determine sparse Jacobians and sparse Hessians for the models in this library. This value is only used by the models if they were compiled with multithreading support.

Returns: the maximum number of threads

Implements CppAD::cg::ModelLibrary< Base >.

Definition at line 122 of file functor_model_library.hpp.

◆ getThreadPoolNumberOfTimeMeas()

template<class Base >

unsigned int CppAD::cg::FunctorModelLibrary< Base >::getThreadPoolNumberOfTimeMeas ( ) const

inlineoverridevirtualinherited

Provides the number of time measurements taken by each computational task during multithreaded model evaluations. This is used to schedule work accross threads. The higher the value the more accurate the time estimations are but it requires additional calls to retrieve times. This value is only used by the models if they were compiled with multithreading support.

Returns: the number of time measurements to take per task.

Implements CppAD::cg::ModelLibrary< Base >.

Definition at line 180 of file functor_model_library.hpp.

◆ getThreadPoolSchedulerStrategy()

template<class Base >

ThreadPoolScheduleStrategy CppAD::cg::FunctorModelLibrary< Base >::getThreadPoolSchedulerStrategy ( ) const

inlineoverridevirtualinherited

Provides the thread scheduling strategy used to determine sparse Jacobians and sparse Hessians for the models in this library. This value is only used by the models if they were compiled with multithreading support.

Returns: the thread scheduling strategy

Implements CppAD::cg::ModelLibrary< Base >.

Definition at line 135 of file functor_model_library.hpp.

◆ isThreadPoolDisabled()

template<class Base >

bool CppAD::cg::FunctorModelLibrary< Base >::isThreadPoolDisabled ( ) const

inlineoverridevirtualinherited

Determines whether or not multithreaded model evaluations are disabled.

Returns: true if only the current thread is used to evaluate models.

Implements CppAD::cg::ModelLibrary< Base >.

Definition at line 115 of file functor_model_library.hpp.

◆ loadFunction()

template<class Base >

void* CppAD::cg::LlvmModelLibraryImpl< Base >::loadFunction	(	const std::string &	functionName,
		bool	required = `true`
	)

inlineoverridevirtual

Provides a pointer to a function in the model library.

Parameters

functionName	The name of the function in the dynamic library
required	Whether or not the function symbol must exist in the library. If the function is required and does not exist then the CppAD error handler is called, if it is not required and it does not exist then nullptr is return.

Returns: A pointer to the function symbol in the dynamic library if it exists, nullptr otherwise.

Exceptions

CGException If there is a problem loading the function symbol

Implements CppAD::cg::FunctorModelLibrary< Base >.

Definition at line 87 of file llvm_model_library_impl.hpp.

◆ model()

template<class Base >

std::unique_ptr<GenericModel<Base> > CppAD::cg::FunctorModelLibrary< Base >::model ( const std::string & modelName )

inlinefinaloverridevirtualinherited

Creates a new GenericModel object that can be used to evaluate the model.

Parameters

modelName The model name.

Returns: The model object or nullptr if no model exists with the provided name.

Implements CppAD::cg::ModelLibrary< Base >.

template<class Base >

void CppAD::cg::FunctorModelLibrary< Base >::setThreadNumber ( unsigned int n )
