Initializes the constraint. This will remove all levels of
indirection present, such as references to types or values. No
constraint information is lost by this operation. This method
may modify this object as a side-effect, and will be called by
the MIB loader.
Checks if the specified value is compatible with this
constraint. Only octet string values can be compatible with a
size constraint, and only if the string length is compatible
with the value range in the size constraint.
