Member Function Documentation

blockTip()

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

overridevirtual

Reimplemented from kernel::Notifications.

Definition at line 60 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 92 of file kernel_notifications.cpp.

Here is the call graph for this function:

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.

Reimplemented from kernel::Notifications.
