    • matchSingle

      public boolean matchSingle(StackFrame frame)
      Matches
      invalid reference 
      #getRule()
      for the automatic single stage, if applicable.
      Parameters:
      frame - the stack frame in which to execute the matcher
      Returns:
      true iff the rule has any matches

    • matchRecursive

      public boolean[] matchRecursive(StackFrame frame)
      Matches
      invalid reference 
      #getRule()
      for the automatic recursive stage, if applicable.
      Parameters:
      frame - the stack frame in which to execute the matcher
      Returns:
      true iff the rule has any matches

    • matchManual

      public Object matchManual(StackFrame frame, Object[] values)
      Matches
      invalid reference 
      #getRule()
      manually, if applicable.
      Parameters:
      frame - the stack frame in which to execute the matcher
      values - the values to match against
      Returns:
      the rule application result, or null if the rule did not match
      Throws:
      VMException - if this is not a RuleMode.MANUAL rule

    • matchManualTrace

      public TraceLink matchManualTrace(StackFrame frame, Object[] values)
      Matches
      invalid reference 
      #getRule()
      manually, if applicable. Because this method returns the application trace rather than the return value, it can be invoked in a reentrant manner (i.e. while still evaluating the previous invocation).
      Parameters:
      frame - the stack frame in which to execute the matcher
      values - the values to match against
      Returns:
      the rule application trace, or null if the rule did not match
      Throws:
      VMException - if this is not a RuleMode.MANUAL rule

    • matchFor

      public abstract boolean matchFor(StackFrame frame, Object[] values)
      Matches this rule against values, and records a match in ExecEnv.getMatches() in case of a match. In case of a unique rule, this method will not match if the rule has already matched against values before.
      Parameters:
      frame - the stack frame context
      values - the source values to match against
      Returns:
      true iff this rule matches against values

    • matchFor

      public abstract boolean matchFor(StackFrame frame, Map<String,Object> valuesMap, Object[] values)
      Matches this rule against values, and records a match in ExecEnv.getMatches() in case of a match. In case of a unique rule, this method will not match if the rule has already matched against values before.
      Parameters:
      frame - the stack frame context
      valuesMap - the map of all values, including super-rule elements
      values - the source values to match against
      Returns:
      true iff this rule matches against values
