    • nextTraceEntry

      public TraceEntry nextTraceEntry(TraceEntry entry)
      Return the trace entry immediately following the entry entry. Returns null if entry is the last entry in the trace.
      Parameters:
      entry - the current trace entry
      Returns:
      the next trace entry

    • previousTraceEntry

      public TraceEntry previousTraceEntry(TraceEntry entry)
      Return the trace entry immediately preceding the entry entry. Returns null if entry is the first entry in the trace.
      Parameters:
      entry - the current trace entry
      Returns:
      the previous trace entry

    • getRules

      public List<String> getRules()
      Get a list of the rules that appear in the trace.
      Returns:
      a list of the names of the rules that appear in the trace.

    • getRuleTraces

      public List<RuleTrace> getRuleTraces(String ruleName)
      Get a list of the rule traces for the named rule.
      Parameters:
      ruleName - the name of the rule
      Returns:
      a list of rule traces for the specified rule.

    • getFactTypes

      public List<String> getFactTypes()
      Get a list of the fact types that appear in the trace.
      Returns:
      a list of the fact types that appear in the trace.

    • getLastFactTraces

      public List<FactTrace> getLastFactTraces(String factType)
      Get a list, for each fact of the specified type, of the last fact trace available in the trace.
      Parameters:
      factType - the fact type name.
      Returns:
      a list, for each fact of the specified type, of the last fact trace available in the trace.

    • getLastFactTrace

      public FactTrace getLastFactTrace(int factId)
      Get the last fact trace for the fact with the ID factId.
      Parameters:
      factId - the fact ID.
      Returns:
      the last fact trace for the fact with the ID factId else null if no such fact exists in the trace.

    • getFactTraces

      public List<FactTrace> getFactTraces(int factId)
      Get a list of the fact traces for the fact with the ID factId.
      Parameters:
      factId - the fact ID.
      Returns:
      a list of the fact traces for the fact with the ID.

    • whichRule

      public RuleTrace whichRule(FactTrace factTrace)
      Get the rule trace for the rule whose action affected the fact in the fact trace. Null is returned if the fact trace was not a result of a rule action.
      Parameters:
      factTrace - the fact trace
      Returns:
      the rule trace or null if the fact trace was not a result of a rule action.

    • getRuleMatchedFacts

      public List<FactTrace> getRuleMatchedFacts(RuleTrace ruleTrace)
      Get a list of traces for the facts that matched resulting in the rule trace.
      Parameters:
      ruleTrace - the rule trace
      Returns:
      a list of fact traces for the facts that matched for this rule trace.

    • getActivationMatchedFacts

      public List<FactTrace> getActivationMatchedFacts(ActivationTrace activationTrace)

      Parameters:
      activationTrace - the activation trace
      Returns:
      a list of fact traces for the facts that matched for this activation trace.
