Detailed Description

A FunctionFactoryCollection instance is a FunctionFactory in its own right, but looks in its contained collection of factories for requested functions.

Note: the order of adding function libraries is significant.

◆ isAvailable()

bool FunctionFactoryCollection::isAvailable	(	const NamePool::Ptr &	np,
		const QXmlName	name,
		const xsInteger	arity
	)

virtual

Determines whether a function with the name name and arity arity is available. The implementation operates on the result of retrieveFunctionSignature() to determine the result.

Parameters

np	the NamePool.
name	the name of the function. For example fn:string-join.
arity	the number of arguments the function must have.

Reimplemented from QPatternist::FunctionFactory.

         if((*it)->isAvailable(np, name, arity))
             return true;
 
     return false;
 }

◆ retrieveFunctionSignature()

FunctionSignature::Ptr FunctionFactoryCollection::retrieveFunctionSignature	(	const NamePool::Ptr &	np,
		const QXmlName	name
	)

virtual

This is a convenience function for sub-classes. It retrieves the function signature for function with name name.

According to the specifications are function signatures identified by their name and arity, but currently is the arity not part of the signature.

If no function could be found for the given name, null is returned.

 }

◆ xpath20Factory()

FunctionFactory::Ptr FunctionFactoryCollection::xpath20Factory ( const NamePool::Ptr & np )

static

Returns: a FunctionFactory containing all core functions and constructor functions required for XPath 2.. The functions specified for XQuery 1.0 are the same as for XPath 2.0 so this FunctionFactory work for XQuery as well.
