pack32() [1/2]

int IdDictDictionary::pack32	(	const ExpandedIdentifier &	id,

Pack to 32bits the subset of id between (inclusive) index1 and index2 - this is generic, i.e.

not the most efficient

Assumptions:

• packedId is initialized to 0
• the expanded id begins at index = 0
• index1,2 correspond to the level/field number, this is thus the same as the index into the expanded id due to the previous assumption.

First we need to check whether the specified identifier really matches the Dictionary specifications.

However, we stop the search in the set of regions at the first matching region. Should we request that only one region matches ????

Pack to 32bits the subset of id between (inclusive) index1 and index2.

Here one must provide the region index, which can be found with find_region. This is more efficient than the above pack32.

Assumptions: (different than the previous pack32)

• packedId is NOT initialized to 0 - allows to just overwrite the specified fields
• the field array begins at index1, i.e. NOT the first field
• the field array field array has a length of index2-index1+1
• index1,2 correspond to the level/field number
• first_field_index defines the offset for packing. Normally, this is this is 0. But this may be a field > 0, but of course <= index1

		const Identifier &	id,
		const ExpandedIdentifier &	prefix,
		size_t	index2,

Unpack the value_type id to a string for a given group, considering the provided prefix (result will include the prefix) and up to index2 - (index1 is assumed to be 0, i.e.

part of prefix).

Returns 0 on success, nonzero on error.

int IdDictDictionary::unpack	(	const std::string &	group,

verify()

bool IdDictDictionary::verify

(

)

const

Here, we verify global constraints : (this must only be applied after the resolve_references and generate_implementation operations)

a) There should be no overlap between any region duet.

b) In a dictionary, a given field (ie. with a given name) must always be referenced at the same depth across all regions and subregions.

c) When a region specifies a reference to a sub-dictionary :

• the reference must be the last entry in the region
• the first region entries of all regions should not overlap (regardless of the definition of the sub-dictionary). IE the first fields in these regions must be sufficient to unambiguously select the sub-dictionary.

d) Within a dictionary, a given field must always be described either through an enumeration, or through its bounds. However, the various usages of a given field may specify different tag set (for enumerations) or bounds (for a bounded field).
