Member Function Documentation

blockTip()

virtual InterruptResult kernel::Notifications::blockTip ( SynchronizationState  state, CBlockIndex &  index  )

inlinevirtual

Reimplemented in node::KernelNotifications.

Definition at line 38 of file notifications_interface.h.

Here is the caller graph for this function:

fatalError()

virtual void kernel::Notifications::fatalError ( const bilingual_str &  message )

inlinevirtual

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 in node::KernelNotifications.

Definition at line 58 of file notifications_interface.h.

Here is the caller graph for this function:

flushError()

virtual void kernel::Notifications::flushError ( const bilingual_str &  message )

inlinevirtual

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 in node::KernelNotifications.

Definition at line 49 of file notifications_interface.h.

Here is the caller graph for this function:

headerTip()

virtual void kernel::Notifications::headerTip ( SynchronizationState  state, int64_t  height, int64_t  timestamp, bool  presync  )

inlinevirtual

Reimplemented in node::KernelNotifications.

Definition at line 39 of file notifications_interface.h.

Here is the caller graph for this function:

progress()

virtual void kernel::Notifications::progress ( const bilingual_str &  title, int  progress_percent, bool  resume_possible  )

inlinevirtual

Reimplemented in node::KernelNotifications.

Definition at line 40 of file notifications_interface.h.

Here is the caller graph for this function:

warning()

virtual void kernel::Notifications::warning ( const bilingual_str &  warning )

inlinevirtual

Reimplemented in node::KernelNotifications.
