Detailed Description

Member Function Documentation

call()

void rotor::handler_intercepted_t::call ( message_ptr_t &  )

overridevirtualnoexcept

attempt to delivery message to the handler

The message is delivered only if its type matches to the handler message type, otherwise it is silently ignored

Implements rotor::handler_base_t.

call_no_check()

void rotor::handler_intercepted_t::call_no_check ( message_ptr_t &  )

overridevirtualnoexcept

unconditionally invokes the handler for the message

It assumes that the handler is able to handle the message. See select method.

Implements rotor::handler_base_t.

message_type()

const void * rotor::handler_intercepted_t::message_type ( ) const

overridevirtualnoexcept

unique per-message-type pointer used for routing

Implements rotor::handler_base_t.

select()

bool rotor::handler_intercepted_t::select ( message_ptr_t &  )

overridevirtualnoexcept

returns true if the message can be handled by the handler

Implements rotor::handler_base_t.

upgrade()

handler_ptr_t rotor::handler_intercepted_t::upgrade ( const void *  tag )

overridevirtualnoexcept

"upgrades" handler by tagging it

Conceptually it intercepts handler call and does tag-specific actions

Reimplemented from rotor::handler_base_t.
