public interface ProcessStemValues
extends Constants

Interface for processors that traverse stems. Each method gets the current key. Note that there are not methods for sets or stems here since these are handled differently at lower levels, i.e. you must recurse through them. Effectively, this processes scalars only. ProcessScalar processes each element in a nested stem or set. ProcessStemAxisRestriction treats the stems or sets along an axis as aggregates. This handles Java objects, not QDLValues. To return a QDL value, wrap it using QDLValue.asQDLValue(Object).

Usage

Each call has an index that is the stem path to the coordinates. So if you access A.b.c.d, then the index is [b,c] and the key is d.

Note that the default value here refers to the default for this processor, i.e., what to return if there is no other logic. It ranges from just handing it back for the identity processor to throwing an exception in almost every case for the no-op processor.
