|
| asMap | | public static Map asMap(Object[][] source, Map target, boolean reverse)(Code) | | Utility like Arrays.asList()
|
| flatten | | public static UnicodeSet flatten(UnicodeSet exemplar1)(Code) | | Modifies Unicode set to flatten the strings. Eg [abc{da}] => [abcd]
Returns the set for chaining.
Parameters:
exemplar1 - |
| getContainmentRelation | | public static int getContainmentRelation(Collection a, Collection b)(Code) | | Assesses all the possible containment relations between collections A and B with one call.
Returns an int with bits set, according to a "Venn Diagram" view of A vs B.
NOT_A_SUPERSET_B: a - b != {}
NOT_A_DISJOINT_B: a * b != {} // * is intersects
NOT_A_SUBSET_B: b - a != {}
Thus the bits can be used to get the following relations:
for A_SUPERSET_B, use (x & CollectionUtilities.NOT_A_SUPERSET_B) == 0
for A_SUBSET_B, use (x & CollectionUtilities.NOT_A_SUBSET_B) == 0
for A_EQUALS_B, use (x & CollectionUtilities.NOT_A_EQUALS_B) == 0
for A_DISJOINT_B, use (x & CollectionUtilities.NOT_A_DISJOINT_B) == 0
for A_OVERLAPS_B, use (x & CollectionUtilities.NOT_A_DISJOINT_B) != 0
