Detailed Description

Wrapper for HostCallback instances.

Provides a way to specify a callback using one of the following options:

• An implementation of the HostCallback interface
• A C++ lambda expression
• An instance of std::function

Constructor & Destructor Documentation

HostCallbackHandle() [1/2]

template<class CallbackImpl , typename = typename std::enable_if< std::is_base_of<HostCallback, CallbackImpl>::value>::type>

poplar::HostCallbackHandle::HostCallbackHandle ( std::unique_ptr< CallbackImpl >  f )

inline

Constructs a handle from an instance of a host callback implementation.

This constructor only participates in overload resolution if CallbackImpl is derived from poplar::HostCallback (in other words, it is an implementation of the host callback interface).

HostCallbackHandle() [2/2]

template<class F , typename = typename std::enable_if< traits::is_host_callback<F>::value>::type>

poplar::HostCallbackHandle::HostCallbackHandle ( F &&  f )

inline

Constructs a handle from a callable instance.

This constructor only participates in overload resolution if F satisfies the requirements of a Function Object. It transforms f into a HostCallback implementation.
