Class AcDbBatchProcessing

Class used to break up work into smaller chunks that are executed asynchronously.

This is often referred to as "batch processing" or "cooperative multitasking," where the time-consuming task is broken into smaller pieces and executed in small intervals to allow the UI to remain responsive.

Example

const batchProcessor = new AcDbBatchProcessing(1000, 10, 50);
await batchProcessor.processChunk(async (start, end) => {
  // Process items from start to end
  for (let i = start; i < end; i++) {
    // Process item i
  }
});

constructor

  • new AcDbBatchProcessing(
        count: number,
        numerOfChunk: number,
        minimumChunkSize: number,
    ): AcDbBatchProcessing

  • Creates a new AcDbBatchProcessing instance.

    Parameters

    • count: number

      The total number of items to process

    • numerOfChunk: number

      The number of chunks to process

    • minimumChunkSize: number

      The minimum number of items in one chunk. If it is greater than the total number of items to process, the total number is used.

    Returns AcDbBatchProcessing

    Example

    const batchProcessor = new AcDbBatchProcessing(1000, 10, 50);

Methods

processChunk

  • processChunk(
        callback: AcDbChunkProcessingCallback,
        onComplete?: AcDbChunkProcessingCompleteCallback,
    ): Promise<void>

  • Processes items in chunks using the provided callback function.

    This method breaks up the work into chunks and processes each chunk asynchronously, allowing the UI to remain responsive.

    Parameters

    • callback: AcDbChunkProcessingCallback

      The callback function to execute for each chunk

    • OptionalonComplete: AcDbChunkProcessingCompleteCallback

    Returns Promise<void>

    Promise that resolves when all chunks have been processed

    Example

    await batchProcessor.processChunk(async (start, end) => {
      for (let i = start; i < end; i++) {
        // Process item i
        await processItem(i);
      }
    });
