Enumeration Type Documentation

enum relation_t

Partial order relations between two sets: the values depend on "exactness" of relations. Enumeration values: base_DIFFERENT  incomparable | not (set1 <= set2) base_SUPERSET  set1 > set2 | not used base_GREATER  same as superset | base_SUBSET  set1 < set2 | set1 <= set2 base_LESS  same as subset | base_EQUAL  set1 == set2 | not used

Function Documentation

static relation_t base_sub2super (  relation_t  rel  )  [inline, static]

Convertion from subset to superset.

static relation_t base_super2sub (  relation_t  rel  )  [inline, static]

Conversion from superset to subset.

static relation_t base_symRelation (  relation_t  rel  )  [inline, static]

Returns: the symmetric relation (useful when swapping arguments for a relation): different -> different superset -> subset subset -> superset equal -> equal Implementation: invert the superset and subset bits. Parameters: rel,:  relation to invert.
