All Implemented Interfaces:

Callable, FunctionItem, GroundedValue, Item, Sequence

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()

setParseOptions

public static ParseOptions setParseOptions(RetainedStaticContext rsc,
                                           java.util.Map<java.lang.String,GroundedValue> checkedOptions,
                                           XPathContext context)
                                    throws XPathException

Throws:

XPathException

call

public Sequence call(XPathContext context,
                     Sequence[] arguments)
              throws XPathException

Evaluate the expression

Specified by:

call in interface Callable

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

Returns:

the properties
