Class UriCollection
java.lang.Object
net.sf.saxon.expr.Expression
net.sf.saxon.expr.FunctionCall
net.sf.saxon.functions.SystemFunction

- All Implemented Interfaces:
- Serializable, SourceLocator, LocationProvider, SaxonLocator, CallableExpression, InstructionInfo, Locator
public class UriCollection
- extends SystemFunction
- implements CallableExpression
Implement the fn:uri-collection() function (new in XQuery 3.0/XSLT 3.0). This is responsible for calling the
registered CollectionURIResolver
. For the effect of the default
system-supplied CollectionURIResolver, see StandardCollectionURIResolver

UriCollection
public UriCollection()
getStaticBaseURI
public String getStaticBaseURI()
checkArguments
public void checkArguments(ExpressionVisitor visitor)
throws XPathException
- Description copied from class:
SystemFunction
- Method called during static type checking
- Overrides:
checkArguments
in class SystemFunction
- Parameters:
visitor
- the expression visitor
- Throws:
XPathException
- if the arguments are incorrect
preEvaluate
public Expression preEvaluate(ExpressionVisitor visitor)
- preEvaluate: this method suppresses compile-time evaluation by doing nothing
- Overrides:
preEvaluate
in class FunctionCall
- Parameters:
visitor
- an expression visitor
- Returns:
- the result of the early evaluation, or the original expression, or potentially
a simplified expression
iterate
public SequenceIterator iterate(XPathContext context)
throws XPathException
- Iterate over the contents of the collection
- Overrides:
iterate
in class Expression
- Parameters:
context
- the dynamic context
- Returns:
- an iterator, whose items will always be nodes (typically but not necessarily document nodes)
- Throws:
XPathException
call
public SequenceIterator call(SequenceIterator[] arguments,
XPathContext context)
throws XPathException
- Evaluate the expression
- Specified by:
call
in interface CallableExpression
- Parameters:
arguments
- the values of the arguments, supplied as SequenceIteratorscontext
- the dynamic evaluation context
- 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
