Member Function Documentation

◆ Evaluate()

virtual SharedPtr<Object> System::Xml::Xsl::IXsltContextVariable::Evaluate ( SharedPtr< XsltContext xsltContext)
pure virtual

Evaluates the variable at runtime and returns an object that represents the value of the variable.

Parameters
xsltContextAn XsltContext representing the execution context of the variable.
Returns
An Object representing the value of the variable. Possible return types include number, string, Boolean, document fragment, or node set.

◆ get_IsLocal()

virtual bool System::Xml::Xsl::IXsltContextVariable::get_IsLocal ( )
pure virtual

Returns a value indicating whether the variable is local.

Returns
true if the variable is a local variable in the current context; otherwise, false.

◆ get_IsParam()

virtual bool System::Xml::Xsl::IXsltContextVariable::get_IsParam ( )
pure virtual

Returns a value indicating whether the variable is an Extensible Stylesheet Language Transformations (XSLT) parameter. This can be a parameter to a style sheet or a template.

Returns
true if the variable is an XSLT parameter; otherwise, false.

◆ get_VariableType()

virtual System::Xml::XPath::XPathResultType System::Xml::Xsl::IXsltContextVariable::get_VariableType ( )
pure virtual

Returns the XPathResultType representing the XML Path Language (XPath) type of the variable.

Returns
The XPathResultType representing the XPath type of the variable.
