public final class CharTypes extends Object

  • Field Details

    • HC

      protected static final char[] HC

    • HClower

      protected static final char[] HClower

    • HB

      protected static final byte[] HB

    • HBlower

      protected static final byte[] HBlower

    • sInputCodes

      protected static final int[] sInputCodes
      Lookup table used for determining which input characters need special handling when contained in text segment.

    • sInputCodesUTF8

      protected static final int[] sInputCodesUTF8
      Additionally we can combine UTF-8 decoding info into similar data table.

    • sInputCodesJsNames

      protected static final int[] sInputCodesJsNames
      To support non-default (and non-standard) unquoted Object Property names mode, need to have alternate checking. Basically this is list of 8-bit ASCII characters that are legal as part of Javascript identifier

    • sInputCodesUtf8JsNames

      protected static final int[] sInputCodesUtf8JsNames
      This table is similar to Latin-1, except that it marks all "high-bit" code as ok. They will be validated at a later point, when decoding name

    • sInputCodesComment

      protected static final int[] sInputCodesComment
      Decoding table used to quickly determine characters that are relevant within comment content.

    • sInputCodesWS

      protected static final int[] sInputCodesWS
      Decoding table used for skipping white space and comments.
      Since:
      2.3

    • sOutputEscapes128NoSlash

      protected static final int[] sOutputEscapes128NoSlash
      Lookup table used for determining which output characters in 7-bit ASCII range need to be quoted.

    • sOutputEscapes128WithSlash

      protected static final int[] sOutputEscapes128WithSlash
      Lookup table same as sOutputEscapes128NoSlash except that forward slash ('/') is also escaped

    • sHexValues

      protected static final int[] sHexValues
      Lookup table for the first 256 Unicode characters (ASCII / UTF-8) range. For actual hex digits, contains corresponding value; for others -1.

      NOTE: before 2.10.1, was of size 128, extended for simpler handling

  • Method Details

    • getInputCodeLatin1

      public static int[] getInputCodeLatin1()

    • getInputCodeUtf8

      public static int[] getInputCodeUtf8()

    • getInputCodeLatin1JsNames

      public static int[] getInputCodeLatin1JsNames()

    • getInputCodeUtf8JsNames

      public static int[] getInputCodeUtf8JsNames()

    • getInputCodeComment

      public static int[] getInputCodeComment()

    • getInputCodeWS

      public static int[] getInputCodeWS()

    • get7BitOutputEscapes

      public static int[] get7BitOutputEscapes()
      Accessor for getting a read-only encoding table for first 128 Unicode code points (single-byte UTF-8 characters). Value of 0 means "no escaping"; other positive values that value is character to use after backslash; and negative values that generic (backslash - u) escaping is to be used.
      Returns:
      128-entry int[] that contains escape definitions

    • get7BitOutputEscapes

      public static int[] get7BitOutputEscapes(int quoteChar, boolean escapeSlash)
      Alternative to get7BitOutputEscapes() when either a non-standard quote character is used, or forward slash is to be escaped.
      Parameters:
      quoteChar - Character used for quoting textual values and property names; usually double-quote but sometimes changed to single-quote (apostrophe)
      escapeSlash - Whether forward slash ("/") is escaped by default or not.
      Returns:
      128-entry int[] that contains escape definitions
      Since:
      2.17

    • charToHex

      public static int charToHex(int ch)

    • hexToChar

      public static char hexToChar(int ch)

    • appendQuoted

      public static void appendQuoted(StringBuilder sb, String content)
      Helper method for appending JSON-escaped version of contents into specific StringBuilder, using default JSON specification mandated minimum escaping rules.
      Parameters:
      sb - Buffer to append escaped contents in
      content - Unescaped String value to append with escaping applied

    • copyHexChars

      public static char[] copyHexChars(boolean uppercase)

    • copyHexBytes

      public static byte[] copyHexBytes(boolean uppercase)
