blockTip()

kernel::InterruptResult node::KernelNotifications::blockTip ( SynchronizationState state, const CBlockIndex & index, double verification_progress )

nodiscardoverridevirtual

Reimplemented from kernel::Notifications.

Definition at line 51 of file kernel_notifications.cpp.

fatalError()

void node::KernelNotifications::fatalError ( const bilingual_str & message )

overridevirtual

The fatal error notification is sent to notify the user when an error occurs in kernel code that can't be recovered from. After this notification is sent, whatever function triggered the error should also return an error code or raise an exception. Applications can choose to handle the fatal error notification by logging the error, or notifying the user, or triggering an early shutdown as a precaution against causing more errors.

Reimplemented from kernel::Notifications.

Definition at line 97 of file kernel_notifications.cpp.

flushError()

void node::KernelNotifications::flushError ( const bilingual_str & message )

overridevirtual

The flush error notification is sent to notify the user that an error occurred while flushing block data to disk. Kernel code may ignore flush errors that don't affect the immediate operation it is trying to perform. Applications can choose to handle the flush error notification by logging the error, or notifying the user, or triggering an early shutdown as a precaution against causing more errors.
