Detailed Description

template<typename T>
class turi::lazy_eval_future< T >

The lazy_eval_future<T> is the key object managed by the lazy_eval_operation_dag. All operations issued to the dag returns a future object. Evaluating the future (using operator()) will evaluate the DAG allowing the object to be accessed efficiently.

Member Function Documentation

get_ptr()

template<typename T >

std::shared_ptr<value_type> turi::lazy_eval_future< T >::get_ptr ( )

inline

Evaluates the dependencies of this object, caches the result, and returns a a shared pointer to the computed value. If the value has already been cached, no further computation is performed.

Definition at line 73 of file lazy_eval_operation_dag.hpp.

is_available()

template<typename T >

bool turi::lazy_eval_future< T >::is_available ( )

inline

Returns true if the object has been computed.

Definition at line 92 of file lazy_eval_operation_dag.hpp.

operator()()

template<typename T >

value_type& turi::lazy_eval_future< T >::operator() ( )

inline

Evaluates the dependencies of this object, caches the result, and returns a reference to the computed value. If the value has already been cached, no further computation is performed.

Definition at line 62 of file lazy_eval_operation_dag.hpp.

reset()

template<typename T >

void turi::lazy_eval_future< T >::reset ( )

inline

Clears the contents of the future. All shared pointers obtained from the object are still valid.
