Member Function Documentation

virtual bool esve::kernel::Caching_Node::stop_caching (   )  [virtual]

Emit the cache; stop caching handle_*() messages. Returns: The or'd result of the emitted handle_*() return values.

virtual void esve::kernel::Caching_Node::discard_cache (   )  [virtual]

Throw away the contents of the cache; do not emit anything. Does not affect caching state.

bool esve::kernel::Caching_Node::active (   )  const [virtual]

Whether to pass messages to children. When active(), messages are relayed from parents to children. When active() == false, no messages are relayed. Implements esve::message::Active_State.

void esve::kernel::Caching_Node::active (  bool   )  [virtual]

Whether to pass messages to children. When active(), messages are relayed from parents to children. When active() == false, no messages are relayed. Implements esve::message::Active_State.
