Methods

Optional Abstract finally

This method should always be called at the end of the reading process so that we can properly clean up.

Returns Promise<void>

Abstract readBytes

readBytes(offset: number, count: number): Promise<ArrayBufferLike>

- Defined in @here/olp-sdk-dataservice-write/lib/utils/BlobData.ts:36

Gets buffer from a range of data.

Parameters
- offset: number
  
  The first byte of the data range for reading.
- count: number
  
  The number of bytes to read from the underlying data. This value will be trimmed if the count exceeded the EOF or end of the stream.
Returns Promise<ArrayBufferLike>

The Promise object with the buffer.

Abstract size

size(): number

- Defined in @here/olp-sdk-dataservice-write/lib/utils/BlobData.ts:43
