Detailed Description

MemDb::ComponentId.

Describes an attributes's type and default value. The attributes type can be omitted by registering it with a size of zero bytes. This essentially means the attribute is only used when querying the database This information is used to allocate the table columns.

Note: This is mostly just used internally by the database and typeregistry, so you most likely won't need to care about this class in normal use-cases.
