extends CharacterEscapes
Class Inheritance
Imports
com.fasterxml.jackson.core.io.CharacterEscapes, .SerializedString
Convenience CharacterEscapes implementation that escapes Unicode characters `0x2028` and `0x2029` (in addition to characters escaped otherwise), which are apparently considered linefeeds as per newer Javascript specifications, and consequently problematic when using JSONP (see https://en.wikipedia.org/wiki/JSONP).
Since
2.8

getEscapeCodesForAscii()

Implements abstract com.fasterxml.jackson.core.io.CharacterEscapes.getEscapeCodesForAscii.

Method generators can call to get lookup table for determining escape handling for first 128 characters of Unicode (ASCII characters.

public SerializableString
getEscapeSequence(int
Character to look escape sequence for

Implements abstract com.fasterxml.jackson.core.io.CharacterEscapes.getEscapeSequence.

Method generators can call to get lookup table for determining exact escape sequence to use for given character.

public int[] getEscapeCodesForAscii()

Implements abstract com.fasterxml.jackson.core.io.CharacterEscapes.getEscapeCodesForAscii.

Doc from com.fasterxml.jackson.core.io.CharacterEscapes.getEscapeCodesForAscii.

Method generators can call to get lookup table for determining escape handling for first 128 characters of Unicode (ASCII characters. Caller is not to modify contents of this array, since this is expected to be a shared copy.

Returns:int[]

Array with size of at least 128, where first 128 entries have either one of ESCAPE_xxx constants, or non-zero positive integer (meaning of which is data format specific; for JSON it means that combination of backslash and character with that value is to be used) to indicate that specific escape sequence is to be used.

public SerializableString getEscapeSequence(int ch)

Implements abstract com.fasterxml.jackson.core.io.CharacterEscapes.getEscapeSequence.

Doc from com.fasterxml.jackson.core.io.CharacterEscapes.getEscapeSequence.

Method generators can call to get lookup table for determining exact escape sequence to use for given character. It can be called for any character, but typically is called for either for ASCII characters for which custom escape sequence is needed; or for any non-ASCII character.

Parameters
ch:int

Character to look escape sequence for

Returns:SerializableString

Escape sequence to use for the character, if any; null if not
