Struct Documentation

template<typename paramsT = void_t, typename resultsT = void_t> struct command_context : public liberate::concurrency::command::command_context_base 

The actual command contexts expands upon the base by providing a parameter and result type. Note that in order to pass multiple parameters or results, you can use a struct or tuple, etc. here.

Param paramsT: [in] The type of parameter the command context can hold.
Param resultsT: [in] The result type the command context can hold.

Public Types

using params_type = paramsT : Alias for template parameter paramsT.

using results_type = resultsT : Alias for template parameter resultsT.

Public Functions

inline explicit command_context(command_type _type)

Like its ancestor, the command_context is initialized with a command type.

Parameters: _type – [in] the command type for this context.

virtual ~command_context() = default: Virtual destructor

Public Members

std::unique_ptr<params_type> parameters = {}: Commands may hold parameters.

std::unique_ptr<results_type> results = {}: Commands may also hold a result.
