Field Detail

• 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 -standard) unquoted field 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

• sOutputEscapes128

  protected static final int[] sOutputEscapes128

  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 sOutputEscapes128 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 Detail

• 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)

  Alternative to get7BitOutputEscapes() when a non-standard quote character is used.

  Parameters:

  quoteChar - Character used for quoting textual values and property names; usually double-quote but sometimes changed to single-quote (apostrophe)

  Returns:

  128-entry int[] that contains escape definitions

  Since:

  2.10

• 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 -

  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

  public static char[] copyHexChars(boolean uppercase)

• copyHexBytes

  @Deprecated
  public static byte[] copyHexBytes()

  Deprecated. Since 2.14 Use copyHexBytes(boolean) instead

  Returns:

  Copy of array of 16 upper-case hexadecimal characters as bytes

• copyHexBytes

  public static byte[] copyHexBytes(boolean uppercase)
