FeedMaker	getFeedMaker(Expression expression, int arg) Get a FeedMaker, a factory class that creates a Feed to evaluate this expression in streaming mode.

Method Detail

getFeedMaker

public FeedMaker getFeedMaker(Expression expression,
                     int arg)

Description copied from class: StreamingAdjunct

Get a FeedMaker, a factory class that creates a Feed to evaluate this expression in streaming mode.

Overrides:

getFeedMaker in class StreamingAdjunct

Parameters:

expression - the expression to be evaluated in streaming mode

arg - identifies the argument with respect to which the expression is to be inverted: usually 0 to indicate the first argument is the value that is streamed. Argument numbering is the same as the sequence of arguments/operands returned by the method Expression.iterateSubExpressions()

Returns:

a FeedMaker to evaluate the expression, or null if it is not streamable with respect to the specificed argument.

processLeft

public static void processLeft(ResultDocument instr,
               Stack<XPathContext> contextStack,
               Stack<Object> state)
                        throws XPathException

In streaming mode, process the first half of the instruction (for example, to start a new document or element)

Parameters:

instr - the ResultDocument instruction

contextStack - Stack of XPathContext objects. The instruction should use the one at the top of the stack. Some instructions (such as xsl:result-document) create a new context object and add it to the stack, removing it in the corresponding processRight() action.

state - a stack on which the instruction can save state information during the call on processLeft()

Throws:

XPathException - if a dynamic error occurs

processRight

public static void processRight(ResultDocument instr,
                Stack<XPathContext> contextStack,
                Stack<Object> state)
                         throws XPathException

In streaming mode, process the right half of the instruction (for example, to end a new document or element)

Parameters:

instr - the ResultDocument instruction

contextStack - the stack of dynamic context objects

state - a stack on which the instruction can save state information during the call on processLeft()

Throws:

XPathException - if a dynamic error occurs
