ConditionState
PreconditionSet	An interface for preconditions that defines necessary methods

Class Summary

Class	Description
ComparisonPredicateIndex	A class containing information for simple indexation of templates rules of the general form base[expr = vals], and the special case for DITA-OT *[contains(@class,' tag ')] To iterate across candidate rules, the IndexMatcher class can be used, behaving as a sequence iterator to yield successive candidate matching Rules (wrapped in ObjectValue).
EmptyPreconditions	A default null precondition set that does no harm and always permits a rule to be checked
ExpressionCondition
IndexDefn	A definition of a rule indexation pattern
IndexDefn.Indexation	A structure of the expressions needed for indexation.
IndexMatcher	Description for class
Matcher	This class contains the stateful part of the precondition checker, in particular Boolean[] indexedState, which records for each indexed precondition whether it has not yet been determined (null) or has been determined to be true or false.
PreconditionDefn
RealPreconditions	A collection of precondition expressions that can be used to increase efficiency of rule matching for long rule chains.
RewriteDefn
TokenizedCondition	A Precondition 'group' that shares a common tokenization of an XPath expression result
UnifyingDefn	This is the base class for precondition, indexation and rewrite definitions that use pattern/expression unification to determine applicability.
