Functions Documentation

function dispatch

bool dispatcher::dispatch (
    uint64_t code,
    uint64_t act
)

This method will dynamically dispatch an incoming set of actions to

static Contract::on( ActionType )

For this to work the Actions must be derived from eosio::contract

function execute_action

bool dispatcher::execute_action (
    name self,
    name code,
    void(T::*)(Args...) func
)

Unpack the received action and execute the correponding action handler

Template parameters:

  • T - The contract class that has the correponding action handler, this contract should be derived from eosio::contract
  • Q - The namespace of the action handler function
  • Args - The arguments that the action handler accepts, i.e. members of the action

Parameters:

  • obj - The contract object that has the correponding action handler
  • func - The action handler

Returns:

true

Convenient macro to create contract apply handler

Note:

To be able to use this macro, the contract needs to be derived from eosio::contract

Parameters:

  • TYPE - The class name of the contract
  • MEMBERS - The sequence of available actions supported by this contract

Example:

EOSIO_DISPATCH( eosio::bios, (setpriv)(setalimits)(setglimits)(setprods)(reqauth) )
