    • resolveTargetCounter

      public String resolveTargetCounter (String id, String counterName, CounterDigitsGlyphStyle listSymbolType)
      Gets target-counter value for specified ID and counterName. Value is converted according to listSymbolType.
      Parameters:
      id - ID of the element. The first call adds ID to the Map, which means we require its value. The second call returns corresponding value if we already encountered corresponding element
      counterName - name of the counter. The first call adds counterName to the Map, which means we require its value. The second call returns corresponding value if we already encountered corresponding element
      listSymbolType - the list symbol type to convert counter's value. null if conversion is not required.
      Returns:
      target-counter value.

      Parameters:
      id - ID of the element. The first call adds ID at the Map, which means we require its value. The second call returns corresponding value if we already encountered this element
      counterName - name of the counter. The first call adds name at the Map, which means we require its value. The second call returns corresponding value if we already encountered this element
      counterSeparatorStr - separator to separate counters values.
      listSymbolType - the list symbol type to convert counter's value. null if conversion is not required.
