javax.print.attribute.SetOfIntegerSyntax — clojure-interop/javax.print 1.0.5

Class SetOfIntegerSyntax is an abstract base class providing the common implementation of all attributes whose value is a set of nonnegative integers. This includes attributes whose value is a single range of integers and attributes whose value is a set of ranges of integers.

You can construct an instance of SetOfIntegerSyntax by giving it in "string form." The string consists of zero or more comma-separated 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", "5-10", "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 length-1 or length-2 array of ints; 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 length-two array of ints in the form {lower bound, upper bound}. An empty set is represented as a zero-length 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 clj

(contains this x)

Determine if this set-of-integer attribute contains the given value.

x - Integer value. - int

returns: True if this set-of-integer attribute contains the value x, false otherwise. - boolean

equals clj

(equals this object)

Returns whether this set-of-integer attribute is equivalent to the passed in object. To be equivalent, all of the following conditions must be true:

object is not null.

object is an instance of class SetOfIntegerSyntax.

This set-of-integer attribute's members and object's members are the same.

object - Object to compare to. - java.lang.Object

returns: True if object is equivalent to this set-of-integer attribute, false otherwise. - boolean

get-members clj

(get-members this)

Obtain this set-of-integer attribute's members in canonical array form. The returned array is "safe;" the client may alter it without affecting this set-of-integer attribute.

returns: This set-of-integer attribute's members in canonical array form. - int[][]

hash-code clj

(hash-code this)

Returns a hash code value for this set-of-integer attribute. The hash code is the sum of the lower and upper bounds of the ranges in the canonical array form, or 0 for an empty set.

returns: a hash code value for this object. - int

next clj

(next this x)

Determine the smallest integer in this set-of-integer attribute that is greater than the given value. If there are no integers in this set-of-integer attribute greater than the given value, -1 is returned. (Since a set-of-integer attribute can only contain nonnegative values, -1 will never appear in the set.) You can use the next() method to iterate through the integer values in a set-of-integer attribute in ascending order, like this:

 SetOfIntegerSyntax attribute = . . .;
 int i = -1;
 while ((i = attribute.next (i)) != -1)
     {
     foo (i);
     }

x - Integer value. - int

returns: The smallest integer in this set-of-integer attribute that is greater than x, or -1 if no integer in this set-of-integer attribute is greater than x. - int

to-string clj

(to-string this)

Returns a string value corresponding to this set-of-integer attribute. The string value is a zero-length string if this set is empty. Otherwise, the string value is a comma-separated list of the ranges in the canonical array form, where each range is represented as "i" if the lower bound equals the upper bound or "i-j" otherwise.

returns: a string representation of the object. - java.lang.String
