All Implemented Interfaces:

java.lang.Iterable<Function>, Callable, Function, GroundedValue<Function>, Item<Function>, Sequence<Function>

public class Doc_2
extends SystemFunction
implements Callable

Implement the saxon:doc() function - a variant of the fn:doc function with a second argument to supply option parameters. Used to underpin the xsl:source-document instruction with streamable="no".

makeOptionsParameter

public static OptionsParameter makeOptionsParameter()

call

public ZeroOrOne<NodeInfo> call(XPathContext context,
                                Sequence[] arguments)
                         throws XPathException

Evaluate the expression

Specified by:

call in interface Callable

Specified by:

call in interface Function

Parameters:

context - the dynamic evaluation context

arguments - the values of the arguments, supplied as SequenceIterators

Returns:

the result of the evaluation, in the form of a SequenceIterator

Throws:

XPathException - if a dynamic error occurs during the evaluation of the expression

getSpecialProperties

public int getSpecialProperties(Expression[] arguments)

Get the static properties of this expression (other than its type). The result is bit-signficant. These properties are used for optimizations. In general, if property bit is set, it is true, but if it is unset, the value is unknown.

Overrides:

getSpecialProperties in class SystemFunction

Parameters:

arguments - the expressions supplied as arguments to the function
