public abstract class SetOfIntegerSyntax extends Object implements Serializable, Cloneable
You can construct an instance of SetOfIntegerSyntax by giving it in "string
form." The string consists of zero or more commaseparated integer groups.
Each integer group consists of either one integer, two integers separated by
a hyphen (
), or two integers separated by a colon
(:
). Each integer consists of one or more decimal digits
(0
through 9
). Whitespace characters cannot
appear within an integer but are otherwise ignored. For example:
""
, "1"
, "510"
, "1:2,
4"
.
You can also construct an instance of SetOfIntegerSyntax by giving it in
"array form." Array form consists of an array of zero or more integer groups
where each integer group is a length1 or length2 array of
int
s; for example, int[0][]
,
int[][]{{1}}
, int[][]{{5,10}}
,
int[][]{{1,2},{4}}
.
In both string form and array form, each successive integer group gives a range of integers to be included in the set. The first integer in each group gives the lower bound of the range; the second integer in each group gives the upper bound of the range; if there is only one integer in the group, the upper bound is the same as the lower bound. If the upper bound is less than the lower bound, it denotes a null range (no values). If the upper bound is equal to the lower bound, it denotes a range consisting of a single value. If the upper bound is greater than the lower bound, it denotes a range consisting of more than one value. The ranges may appear in any order and are allowed to overlap. The union of all the ranges gives the set's contents. Once a SetOfIntegerSyntax instance is constructed, its value is immutable.
The SetOfIntegerSyntax object's value is actually stored in "canonical
array form." This is the same as array form, except there are no null ranges;
the members of the set are represented in as few ranges as possible (i.e.,
overlapping ranges are coalesced); the ranges appear in ascending order; and
each range is always represented as a lengthtwo array of int
s
in the form {lower bound, upper bound}. An empty set is represented as a
zerolength array.
Class SetOfIntegerSyntax has operations to return the set's members in canonical array form, to test whether a given integer is a member of the set, and to iterate through the members of the set.

contains(IntegerSyntax attribute)
Determine if this setofinteger attribute contains the given integer
attribute's value.

boolean 
equals(Object object)
Returns whether this setofinteger attribute is equivalent to the passed
in object.

int[][] 
getMembers()
Obtain this setofinteger attribute's members in canonical array form.
