Jackson-core 2.16.0 · com.fasterxml.jackson.core.io.CharacterEscapes

Field Summary

Modifier and Type	Field and Description
public static final int	ESCAPE_CUSTOM Value used for lookup tables to indicate that matching characters will need custom escapes; and that another call to `getEscapeSequence` is needed to figure out exact escape sequence to output.
public static final int	ESCAPE_NONE Value used for lookup tables to indicate that matching characters do not need to be escaped.
public static final int	ESCAPE_STANDARD Value used for lookup tables to indicate that matching characters are to be escaped using standard escaping; for JSON this means (for example) using "backslash - u" escape method.

Method Summary

Modifier and Type	Method and Description
public abstract int[]	Returns: 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. getEscapeCodesForAscii() Method generators can call to get lookup table for determining escape handling for first 128 characters of Unicode (ASCII characters.
public abstract SerializableString	Returns: Escape sequence to use for the character, if any; `null` if not getEscapeSequence(int Character to look escape sequence for ch) Method generators can call to get lookup table for determining exact escape sequence to use for given character.
public static int[]	Returns: Set of escapes, similar to `getEscapeCodesForAscii()` (array of 128 `int`s), but a copy that caller owns and is free to modify standardAsciiEscapesForJSON() Helper method that can be used to get a copy of standard JSON escape definitions; this is useful when just wanting to slightly customize definitions.

getEscapeCodesForAscii	back to summary
public abstract int[] 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 abstract int[] getEscapeCodesForAscii()

getEscapeSequence back to summary

getEscapeSequence	back to summary
public abstract SerializableString getEscapeSequence(int ch) 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

public abstract SerializableString getEscapeSequence(int ch)

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
