  • Method Details

    • apply

      public int apply(FormattedStringBuilder output, int leftIndex, int rightIndex)
      Description copied from interface: Modifier
      Apply this Modifier to the string builder.
      Specified by:
      apply in interface Modifier
      Parameters:
      output - The string builder to which to apply this modifier.
      leftIndex - The left index of the string within the builder. Equal to 0 when only one number is being formatted.
      rightIndex - The right index of the string within the string builder. Equal to length when only one number is being formatted.
      Returns:
      The number of characters (UTF-16 code units) that were added to the string builder.

    • getPrefixLength

      public int getPrefixLength()
      Description copied from interface: Modifier
      Gets the length of the prefix. This information can be used in combination with Modifier.apply(org.graalvm.shadowed.com.ibm.icu.impl.FormattedStringBuilder, int, int) to extract the prefix and suffix strings.
      Specified by:
      getPrefixLength in interface Modifier
      Returns:
      The number of characters (UTF-16 code units) in the prefix.

    • getCodePointCount

      public int getCodePointCount()
      Description copied from interface: Modifier
      Returns the number of code points in the modifier, prefix plus suffix.
      Specified by:
      getCodePointCount in interface Modifier

    • isStrong

      public boolean isStrong()
      Description copied from interface: Modifier
      Whether this modifier is strong. If a modifier is strong, it should always be applied immediately and not allowed to bubble up. With regard to padding, strong modifiers are considered to be on the inside of the prefix and suffix.
      Specified by:
      isStrong in interface Modifier
      Returns:
      Whether the modifier is strong.

    • containsField

      public boolean containsField(Format.Field field)
      Description copied from interface: Modifier
      Whether the modifier contains at least one occurrence of the given field.
      Specified by:
      containsField in interface Modifier

    • getParameters

      public Modifier.Parameters getParameters()
      Description copied from interface: Modifier
      Gets a set of "parameters" for this Modifier.
      Specified by:
      getParameters in interface Modifier

    • strictEquals

      public boolean strictEquals(Modifier other)
      Description copied from interface: Modifier
      Returns whether this Modifier equals another Modifier.
      Specified by:
      strictEquals in interface Modifier

    • formatTwoArgPattern

      public static void formatTwoArgPattern(String compiledPattern, FormattedStringBuilder result, int index, PrefixInfixSuffixLengthHelper h, Format.Field field)
      TODO: Like above, this belongs with the rest of the SimpleFormatterImpl code. I put it here so that the SimpleFormatter uses in FormattedStringBuilder are near each other.

      Applies the compiled two-argument pattern to the FormattedStringBuilder.

      This method is optimized for the case where the prefix and suffix are often empty, such as in the range pattern like "{0}-{1}".
