Methods
emitSuccessEvent()
protected emitSuccessEvent<K>(eventType: K, data: Partial<EventPayload<UptimeEvents, K>>): Promise<void>;
Defined in: electron/services/commands/DatabaseCommands.ts:167
Internal
Emits a success event for the command operation.
Type Parameters
K
K extends EventKey<UptimeEvents>
Parameters
eventType
K
The event type to emit.
data
Partial<EventPayload<UptimeEvents, K>>
Additional event data to include in the event payload.
Returns
Promise<void>
Remarks
Used internally to emit a typed event indicating command success, including additional event data.
Inherited from
DatabaseCommand.emitSuccessEvent
execute()
execute(): Promise<DatabaseBackupResult>;
Defined in: electron/services/commands/DatabaseCommands.ts:372
Executes the command operation.
Returns
Promise resolving to the operation result.
Remarks
Performs the main database operation encapsulated by the command.
Throws
When command execution fails.
Overrides
rollback()
rollback(): Promise<void>;
Defined in: electron/services/commands/DatabaseCommands.ts:396
No-op rollback for backup operations.
Returns
Promise<void>
Resolved promise since backup operations are read-only and do not require rollback.
Remarks
Backup operations are inherently safe and do not modify the database state, so no rollback action is necessary. Returns a resolved promise to satisfy the IDatabaseCommand interface contract.
Overrides
validate()
validate(): Promise<{
errors: string[];
isValid: boolean;
}>;
Defined in: electron/services/commands/DatabaseCommands.ts:410
Validates backup operation prerequisites.
Returns
Promise<{
errors: string[];
isValid: boolean;
}>
Resolved promise with validation result indicating success.
Remarks
Backup operations have minimal prerequisites, so validation always succeeds. Returns a resolved promise to satisfy the IDatabaseCommand interface contract.
Overrides
getDescription()
getDescription(): string;
Defined in: electron/services/commands/DatabaseCommands.ts:419
Gets a description of the command for logging and debugging.
Returns
string
Human-readable command description.
