ESCAPE_REPLACEMENTS

public static final Map<Character,String> ESCAPE_REPLACEMENTS

A mapping from an escaped character in the input stream to the character that they should be replaced with.

YAML defines several common and a few uncommon escape sequences.

ESCAPE_CODES

public static final Map<Character,Integer> ESCAPE_CODES

A mapping from a character to a number of bytes to read-ahead for that escape sequence. These escape sequences are used to handle unicode escaping in the following formats, where H is a hexadecimal character:

 \xHH         : escaped 8-bit Unicode character
 \uHHHH       : escaped 16-bit Unicode character
 \UHHHHHHHH   : escaped 32-bit Unicode character

has

public boolean has(int c,
                   String additional)

hasNo

public boolean hasNo(int c,
                     String additional)

escapeChar

public static String escapeChar(String chRepresentation)

Replace a single character with its string representation

Parameters:

chRepresentation - - the char to escape
