- Constructor Detail
- Method Detail
  - getLink
```
 final Link getLink()
```
  - getBytes
```
 final SuspendFunction0<ByteArray> getBytes()
```
  - link
```
 Link link()
```
    Returns the link from which the resource was retrieved.
    It might be modified by the Resource to include additional metadata, e.g. the Content-Type HTTP header in Link.type.
  - read
```
 Try<ByteArray, Resource.Exception> read(LongRange range)
```
    Reads the bytes at the given range.
    When range is null, the whole content is returned. Out-of-range indexes are clamped to the available length automatically.
  - length
```
 Try<Long, Resource.Exception> length()
```
    Returns data length from metadata if available, or calculated from reading the bytes otherwise.
    This value must be treated as a hint, as it might not reflect the actual bytes length. To get the real length, you need to read the whole resource.
  - close
```
 Unit close()
```
    Closes this object and releases any resources associated with it. If the object is already closed then invoking this method has no effect.
