类 AppendObjectRequest

  • public class AppendObjectRequest
extends PutObjectRequest
    Uploads a new object to the specified Baidu Bos bucket. The AppendObjectRequest optionally uploads object metadata and applies a canned access control policy to the new object.

    Baidu Bos never stores partial objects; if during this call an exception wasn't thrown, the entire object was stored.

      • getOffset

        public Long getOffset()
        Gets the offset of the file, which shows the resume position of appendable file.
        返回:
        The offset that indicates the size of data has been uploaded to Baidu bos.

      • setOffset

        public void setOffset​(Long offset)
        Sets the offset of the file, which shows the resume position of appendable file.
        参数:
        offset - The offset indicates the size of data has been uploaded to Baidu bos.

      • withOffset

        public AppendObjectRequest withOffset​(Long offset)
        Sets the offset of the file, which shows the resume position of appendable file.
        参数:
        offset - The offset indicates the size of data has been uploaded to Baidu bos.
        返回:
        This AppendObjectRequest, so that additional method calls to be chained together.

      • withObjectMetadata

        public AppendObjectRequest withObjectMetadata​(ObjectMetadata objectMetadata)
        Sets the optional metadata instructing Baidu Bos how to handle the uploaded data (e.g. custom user metadata, hooks for specifying content type, etc.). Returns this AppendObjectRequest, enabling additional method calls to be chained together.

        If uploading from an input stream, always specify metadata with the content size set. Otherwise the contents of the input stream have to be buffered in memory before being sent to Baidu Bos. This can cause very negative performance impacts.

        覆盖:
        withObjectMetadata 在类中 PutObjectRequest
        参数:
        objectMetadata - The optional metadata instructing Baidu Bos how to handle the uploaded data (e.g. custom user metadata, hooks for specifying content type, etc.).
        返回:
        This AppendObjectRequest, so that additional method calls to be chained together.

      • withFile
