 net.sf.saxon.functions.StandardFunction
| StandardFunction | | abstract public class StandardFunction (Code) | | This class contains static data tables defining the properties of standard functions. "Standard functions"
here means the XPath 2.0 functions, the XSLT 2.0 functions, and a few selected extension functions
which need special recognition.

| Method Summary | |
| public static void | arg(Entry e, int a, ItemType type, int cardinality)
| | public static Entry | getFunction(String name, int arity)
Get the table entry for the function with a given name
Parameters:
name - the name of the function. | | public static Entry | makeEntry(String name, Class implementationClass, int opcode, int minArguments, int maxArguments, ItemType itemType, int cardinality)
Make a table entry describing the signature of a function, with a reference to the implementation class.
Parameters:
name - the function name
Parameters:
implementationClass - the class used to implement the function
Parameters:
opcode - identifies the function when a single class implements several functions
Parameters:
minArguments - the minimum number of arguments required
Parameters:
maxArguments - the maximum number of arguments allowed
Parameters:
itemType - the item type of the result of the function
Parameters:
cardinality - the cardinality of the result of the function the entry describing the function. |
| SAME_AS_FIRST_ARGUMENT | | protected static ItemType SAME_AS_FIRST_ARGUMENT(Code) | | |
| arg | | public static void arg(Entry e, int a, ItemType type, int cardinality)(Code) | | Add information to a function entry about the argument types of the function
Parameters:
e - the entry for the function
Parameters:
a - the position of the argument, counting from zero
Parameters:
type - the item type of the argument
Parameters:
cardinality - the cardinality of the argument |
| getFunction | | public static Entry getFunction(String name, int arity)(Code) | | Get the table entry for the function with a given name
Parameters:
name - the name of the function. This may be an unprefixed local-name for functions in thesystem namespace, or may use the conventional prefix "saxon:" in the case of Saxon extension functionsthat are specially recognized if the function name is known, an Entry containing information about the function. Otherwise,null |
| makeEntry | | public static Entry makeEntry(String name, Class implementationClass, int opcode, int minArguments, int maxArguments, ItemType itemType, int cardinality)(Code) | | Make a table entry describing the signature of a function, with a reference to the implementation class.
Parameters:
name - the function name
Parameters:
implementationClass - the class used to implement the function
Parameters:
opcode - identifies the function when a single class implements several functions
Parameters:
minArguments - the minimum number of arguments required
Parameters:
maxArguments - the maximum number of arguments allowed
Parameters:
itemType - the item type of the result of the function
Parameters:
cardinality - the cardinality of the result of the function the entry describing the function. The entry is incomplete, it does not yet contain informationabout the function arguments. |
