 net.sf.saxon.functions.ExtensionFunctionFactory
| ExtensionFunctionFactory | | public class ExtensionFunctionFactory implements Serializable(Code) | | This class acts as a factory for creating expressions that call extension functions.
A different factory may be registered with the Configuration in order to customize the
behaviour. Alternatively, this factory class can be customized by calling setExtensionFunctionClass
to nominate a subclass of ExtensionFunctionCall to be used to implement calls on extension functions.

| Method Summary | |
| public Expression | makeExtensionFunctionCall(int nameCode, Class theClass, AccessibleObject method, Expression[] arguments)
Factory method to create an expression that calls a Java extension function.
This is always called at XPath compile time.
Parameters:
nameCode - the name of the function name, as represented in the name pool
Parameters:
theClass - the Java class containing the extension function
Parameters:
method - The "accessibleObject" representing a constructor, method, or field correspondingto the extension function
Parameters:
arguments - Array containing the expressions supplied as arguments to the function call. | | public void | setExtensionFunctionClass(Class subclass)
Set the class to be used to represent extension function calls. |
| makeExtensionFunctionCall | | public Expression makeExtensionFunctionCall(int nameCode, Class theClass, AccessibleObject method, Expression[] arguments)(Code) | | Factory method to create an expression that calls a Java extension function.
This is always called at XPath compile time.
Parameters:
nameCode - the name of the function name, as represented in the name pool
Parameters:
theClass - the Java class containing the extension function
Parameters:
method - The "accessibleObject" representing a constructor, method, or field correspondingto the extension function
Parameters:
arguments - Array containing the expressions supplied as arguments to the function call. the constructed ExtensionFunctionCall object (a subclass might return any expressionrepresenting the extension function call). |
| setExtensionFunctionClass | | public void setExtensionFunctionClass(Class subclass)(Code) | | Set the class to be used to represent extension function calls. This must be a subclass
of
ExtensionFunctionCall
Parameters:
subclass - the subclass of ExtensionFunctionCall to be used |
