 net.sf.saxon.value.Cardinality
| Cardinality | | final public class Cardinality (Code) | | This class contains static methods to manipulate the cardinality
property of a type.
Cardinality of expressions is denoted by one of the values ONE_OR_MORE, ZERO_OR_MORE,
ZERO_OR_ONE, EXACTLY_ONE, or EMPTY. These are combinations of the three bit-significant
values ALLOWS_ZERO, ALLOWS_ONE, and ALLOWS_MANY.

| Method Summary | |
| final public static int | add(int c1, int c2)
| | final public static boolean | allowsMany(int cardinality)
| | final public static boolean | allowsZero(int cardinality)
| | public static String | getOccurrenceIndicator(int cardinality)
| | final public static int | multiply(int c1, int c2)
| | final public static boolean | subsumes(int c1, int c2)
Test if one cardinality subsumes another. | | final public static int | sum(int c1, int c2)
| | public static String | toString(int cardinality)
| | final public static int | union(int c1, int c2)
Form the union of two cardinalities. |
| add | | final public static int add(int c1, int c2)(Code) | | Add two cardinalities
|
| allowsMany | | final public static boolean allowsMany(int cardinality)(Code) | | Determine whether multiple occurrences are allowed
|
| allowsZero | | final public static boolean allowsZero(int cardinality)(Code) | | Determine whether empty sequence is allowed
|
| getOccurrenceIndicator | | public static String getOccurrenceIndicator(int cardinality)(Code) | | Get the occurence indicator representing the cardinality
|
| multiply | | final public static int multiply(int c1, int c2)(Code) | | Multiply two cardinalities
|
| subsumes | | final public static boolean subsumes(int c1, int c2)(Code) | | Test if one cardinality subsumes another. Cardinality c1 subsumes c2 if every option permitted
by c2 is also permitted by c1.
Parameters:
c1 - a cardinality
Parameters:
c2 - another cardinality true if if every option permittedby c2 is also permitted by c1. |
| sum | | final public static int sum(int c1, int c2)(Code) | | Form the sum of two cardinalities
|
| toString | | public static String toString(int cardinality)(Code) | | Display the cardinality
|
| union | | final public static int union(int c1, int c2)(Code) | | Form the union of two cardinalities. The cardinality of the expression "if (c) then e1 else e2"
is the union of the cardinalities of e1 and e2.
Parameters:
c1 - a cardinality
Parameters:
c2 - another cardinality the cardinality that allows both c1 and c2 |
