public interface IBlob

Properties

Name Description
Size { get; } Returns the size of the byte sequence in number of bytes. On getting, conforming user agents must return the total number of bytes that can be read by a FileReader or FileReaderSync object, or 0 if the Blob has no bytes to be read.
Type { get; } The ASCII-encoded string in lower case representing the media type of the Blob. On getting, user agents must return the type of a Blob as an ASCII-encoded string in lower case, such that when it is converted to a byte sequence, it is a parsable MIME type, or the empty string – 0 bytes – if the type cannot be determined.

Methods
