Interface QueryVisitor

All Known Implementing Classes:

AbstractQueryValidator, DataComparatorAssembler, DataGraphComparatorAssembler, DataObjectComparatorAssembler, DataObjectHashKeyAssembler, DefaultQueryVisitor, QueryValidator, SQLQueryFilterAssembler, TextQueryFilterAssembler

public interface QueryVisitor

Contains "visit" start/end methods called by query traversal algorithms as various structural nodes are encountered. Helps generalize and separate the traversal logic from clients only needing notifications as various specific nodes are traversed.
