Class BlobRange

java.lang.Object
com.azure.storage.blob.models.BlobRange

public final class BlobRange extends Object
This is a representation of a range of bytes on a blob, typically used during a download operation. This type is immutable to ensure thread-safety of requests, so changing the values for a different operation requires construction of a new object. Passing null as a BlobRange value will default to the entire range of the blob.
