- data: Add types to objects
|
||
|
|
|
||
|
|
As we will soon see, there will be different logical types of objects that are
|
||
|
|
used in different contexts (even though, from the Object Database's point of
|
||
|
|
view, they are just all bytes). In order to lower the chance of using an object
|
||
|
|
in the wrong context we're going to add a type tag for each object.
|
||
|
|
|
||
|
|
The type is just a string that's going to be prepended to the start of the file,
|
||
|
|
followed by a null byte. When reading the file later we'll extract the type and
|
||
|
|
verify that it's indeed the expected type.
|
||
|
|
|
||
|
|
The default type is going to be `blob`, since by default an object is a
|
||
|
|
collection of bytes with no further semantic meaning.
|
||
|
|
|
||
|
|
We can also pass `expected=None` to `get_object()` if we don't want to verify
|
||
|
|
the type. This is useful for the `cat-file` CLI command which is a debug command
|
||
|
|
used for printing all objects.
