public AdjacentTextNodeMergerAdjunct()
getWatchMaker
public WatchMaker getWatchMaker(Expression expression,
List<String> reasonsForFailure)
- Description copied from class:
StreamingAdjunct
- Get a WatchMaker, a factory class that creates a Watch to evaluate this expression
in streaming mode. This method will only be called if the getImplementationMethod()
method of the expression includes the value
Expression.WATCH_METHOD
- Overrides:
getWatchMaker
in class StreamingAdjunct
- Parameters:
expression
- the expression to be evaluated in streaming modereasonsForFailure
- if non-null, this is a list supplied by the caller which will be populated
by the callee with one or more messages indicating why it was not possible to allocate a WatchMaker.
Normally if the list is non-empty on return, the return value from the method will be null.
- Returns:
- a Watchmaker to evaluate the expression, or null if it is not streamable with respect
to the specificed argument.
getFeedMaker
public FeedMaker getFeedMaker(Expression expression,
int arg)
- Description copied from class:
StreamingAdjunct
- Get a FeedMaker, a factory class that creates a Watch to evaluate this expression
in streaming mode.
- Overrides:
getFeedMaker
in class StreamingAdjunct
- Parameters:
expression
- the expression to be evaluated in streaming modearg
- 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 Watchmaker to evaluate the expression, or null if it is not streamable with respect
to the specificed argument.
