public abstract class SetOfIntegerSyntax extends Object implements Cloneable, Serializable
SetOfIntegerSyntax is the abstract base class of all attribute
classes which provide a set of non-negative integers as value (e.g. the
page ranges to print) represented as single values or ranges of values.
A SetOfIntegerSyntax instance consists of an integer array of
ranges. Ranges may have the same lower and upper bound representing a single
integer value. Ranges with a lower bound greater than the upper bound are
null ranges and discarded. Ranges may overlap in their values. In no case
negative integers are allowed.
There are several constructors available:
SetOfIntegerSyntax(int member)SetOfIntegerSyntax(int lowerBound, int upperBound)SetOfIntegerSyntax(int[][] members)int[0][] for empty set of integers, int[][] {{1}}
, int[][] {{1,5}}, int[][] {{1,5},{7,9}},
int[][] {{3,7},{19}}.
SetOfIntegerSyntax(String s)"" for an empty set of integers,
"1", "1-5", "1-5,7-9",
"3-7,19" and "1:2,4".
Internal storage:
The set of integers are stored internally in a normalized array form.
In the normalized array form the set of integer ranges are represented
in as few ranges as possible and overlapping ranges are merged. The ranges
are always represented as an integer array of length two with ranges
stored in {lower bound, upper bound} form. The ranges are stored in
ascending order, without any null ranges.
