Constructor Detail

AccumulatorFunctionCallEE

public AccumulatorFunctionCallEE(Accumulator accumulator,
                         boolean isPostDescentFunction)

Create the call on an accumulator function

Parameters:

accumulator - the accumulator whose value is required

isPostDescentFunction - true if this is the post-descent function name, false for the pre-descent function

Method Detail

iterate

public SequenceIterator<? extends Item> iterate(XPathContext context)
                                         throws XPathException

Description copied from class: Expression

Return an Iterator to iterate over the values of a sequence. The value of every expression can be regarded as a sequence, so this method is supported for all expressions. This default implementation handles iteration for expressions that return singleton values: for non-singleton expressions, the subclass must provide its own implementation.

Overrides:

iterate in class AccumulatorFunctionCallPE

Parameters:

context - supplies the context for evaluation

Returns:

a SequenceIterator that can be used to iterate over the result of the expression

Throws:

XPathException - if any dynamic error occurs evaluating the expression
