Class: DatabaseCommandExecutor

Defined in: electron/services/commands/DatabaseCommands.ts:187

Command executor that provides transaction-like semantics for command execution and rollback.

Remarks​

Maintains a history of executed commands and provides automatic rollback on failure. Supports full rollback of all executed commands in reverse order to maintain transactional integrity.

Constructors​

Constructor​

new DatabaseCommandExecutor(): DatabaseCommandExecutor

Returns​

DatabaseCommandExecutor

Properties​

executedCommands​

private readonly executedCommands: IDatabaseCommand<unknown>[] = []

Defined in: electron/services/commands/DatabaseCommands.ts:189

Array of successfully executed commands for potential rollback operations

Methods​

execute()​

execute<TResult>(command: IDatabaseCommand<TResult>): Promise<TResult>

Defined in: electron/services/commands/DatabaseCommands.ts:209

Executes a command with automatic rollback on failure.

Type Parameters​

TResult​

TResult

The result type returned by the command's execute method.

Parameters​

command​

IDatabaseCommand<TResult>

The IDatabaseCommand to execute.

Returns​

Promise<TResult>

Promise resolving to the command result.

Remarks​

Validates the command before execution. If execution fails, attempts to rollback the command. Adds the command to the history if successful.

Throws​

When command validation or execution fails.

rollbackAll()​

rollbackAll(): Promise<void>

Defined in: electron/services/commands/DatabaseCommands.ts:255

Rolls back all executed commands in reverse order.

Returns​

Promise<void>

Promise resolving when all rollbacks are complete.

Remarks​

Executes rollback operations for all previously executed commands in reverse order to maintain transactional integrity. Individual rollback failures are collected but do not prevent other rollbacks from executing. Uses array index access which is safe for typed arrays (hence the eslint-disable comment).

Throws​

AggregateError containing all rollback failures if any occurred.

clear()​

clear(): void

Defined in: electron/services/commands/DatabaseCommands.ts:291

Clears the command history without performing rollback.

Returns​

void

Remarks​

Removes all references to previously executed commands. Does not attempt to revert any changes.
