Class DateTimeFieldRule.TextStore

java.lang.Object
javax.time.calendar.DateTimeFieldRule.TextStore
Enclosing class:
DateTimeFieldRule<T>
public static final class DateTimeFieldRule.TextStore extends Object
The mapping between integer values and textual representations.

Some fields have a textual representation, such as day-of-week or month-of-year. These textual representations can be captured in this class for printing and parsing.

TextStore is immutable and thread-safe.

  • Field Details

    • locale

      private final Locale locale
      The locale of the text.

    • valueTextMap

      private final Map<Integer,String> valueTextMap
      Map of value to text.

    • textValueMap

      private final Map<String,Integer> textValueMap
      Map of case sensitive text to value.

    • insensitiveTextValueMap

      private final Map<String,Integer> insensitiveTextValueMap
      Map of case insensitive text to value.

    • lengths

      private final int[] lengths
      The lengths of the text items.

  • Constructor Details

    • TextStore

      public TextStore(Locale locale, Map<Integer,String> valueTextMap)
      Constructor.
      Parameters:
      locale - the locale, not null
      valueTextMap - the map of values to text to store, not null

  • Method Details

    • getLocale

      public Locale getLocale()
      Gets the locale that the text relates to.
      Returns:
      the locale for the text, never null

    • getValueTextMap

      public Map<Integer,String> getValueTextMap()
      Gets the map of text for each integer value.
      Returns:
      the unmodifiable map of value to text, never null

    • getValueText

      public String getValueText(int value)
      Gets the text for the specified integer value.

      The text associated with the value is returned, or null if none found.

      Parameters:
      value - the value to get text for
      Returns:
      the text for the field value, null if no text found

    • getTextValueMap

      public Map<String,Integer> getTextValueMap()
      Gets the derived map expressing the value for each text.

      If the value-text map contains duplicate text elements then this map will be empty.

      Returns:
      the unmodifiable map of text to value for the field rule and style, never null

    • matchText

      public long matchText(boolean ignoreCase, String parseText)
      Matches the specified text against the text-value map returning the matched length and value.

      This method is intended for use during parsing, and matches the search text against the text-value map, optionally ignoring case.

      Parameters:
      ignoreCase - true to ignore case during the matching
      parseText - the text to match against
      Returns:
      a long packed result of two int values (for performance in parsing). The value is (parseLength invalid input: '<'invalid input: '<' 32 + matchedValue). Zero is returned if there is no match. Minus one is returned if the text store cannot parse. The parse length can be obtained via (result >>> 32). The value can be obtained via ((int) result).
