Member Function Documentation

◆ get_ArgTypes()

virtual ArrayPtr<System::Xml::XPath::XPathResultType> System::Xml::Xsl::IXsltContextFunction::get_ArgTypes ( )
pure virtual

Returns the supplied XML Path Language (XPath) types for the function's argument list. This information can be used to discover the signature of the function which allows you to differentiate between overloaded functions.

Returns
An array of XPathResultType representing the types for the function's argument list.

◆ get_Maxargs()

virtual int32_t System::Xml::Xsl::IXsltContextFunction::get_Maxargs ( )
pure virtual

Returns the maximum number of arguments for the function. This enables the user to differentiate between overloaded functions.

Returns
The maximum number of arguments for the function.

◆ get_Minargs()

virtual int32_t System::Xml::Xsl::IXsltContextFunction::get_Minargs ( )
pure virtual

Returns the minimum number of arguments for the function. This enables the user to differentiate between overloaded functions.

Returns
The minimum number of arguments for the function.

◆ get_ReturnType()

virtual System::Xml::XPath::XPathResultType System::Xml::Xsl::IXsltContextFunction::get_ReturnType ( )
pure virtual

Returns the XPathResultType representing the XPath type returned by the function.

Returns
An XPathResultType representing the XPath type returned by the function.

◆ Invoke()

virtual SharedPtr<Object> System::Xml::Xsl::IXsltContextFunction::Invoke ( SharedPtr< XsltContext xsltContext,
ArrayPtr< SharedPtr< Object >>  args,
SharedPtr< System::Xml::XPath::XPathNavigator docContext 
)
pure virtual

Provides the method to invoke the function with the given arguments in the given context.

Parameters
xsltContextThe XSLT context for the function call.
argsThe arguments of the function call. Each argument is an element in the array.
docContextThe context node for the function call.
Returns
An Object representing the return value of the function.
