- - ### Constructor Detail

    - #### JavaUnicodeEscaper

          public JavaUnicodeEscaper(int below,
                            int above,
                            boolean between)

      Constructs a `JavaUnicodeEscaper` for the specified range. This is the underlying method for the other constructors/builders. The `below` and `above` boundaries are inclusive when `between` is `true` and exclusive when it is `false`.

      Parameters:
        `below` - int value representing the lowest codepoint boundary
        `above` - int value representing the highest codepoint boundary
        `between` - whether to escape between the boundaries or outside them

  - ### Method Detail

    - #### above

          public static JavaUnicodeEscaper above(int codepoint)

      Constructs a `JavaUnicodeEscaper` above the specified value (exclusive).

      Parameters:
        `codepoint` - above which to escape
      Returns:
        the newly created `UnicodeEscaper` instance

    - #### below

          public static JavaUnicodeEscaper below(int codepoint)

      Constructs a `JavaUnicodeEscaper` below the specified value (exclusive).

      Parameters:
        `codepoint` - below which to escape
      Returns:
        the newly created `UnicodeEscaper` instance

    - #### between

          public static JavaUnicodeEscaper between(int codepointLow,
                                   int codepointHigh)

      Constructs a `JavaUnicodeEscaper` between the specified values (inclusive).

      Parameters:
        `codepointLow` - above which to escape
        `codepointHigh` - below which to escape
      Returns:
        the newly created `UnicodeEscaper` instance

    - #### outsideOf

          public static JavaUnicodeEscaper outsideOf(int codepointLow,
                                     int codepointHigh)

      Constructs a `JavaUnicodeEscaper` outside of the specified values (exclusive).

      Parameters:
        `codepointLow` - below which to escape
        `codepointHigh` - above which to escape
      Returns:
        the newly created `UnicodeEscaper` instance

    - #### toUtf16Escape

          protected String toUtf16Escape(int codepoint)

      Converts the given codepoint to a hex string of the form `"\\uXXXX\\uXXXX"`
      Overrides:
        `toUtf16Escape` in class `UnicodeEscaper`
      Parameters:
        `codepoint` - a Unicode code point
      Returns:
        the hex string for the given codepoint
