Enum JsonEncoding

java.lang.Object

java.lang.Enum<JsonEncoding>

com.fasterxml.jackson.core.JsonEncoding

All Implemented Interfaces:

Serializable, Comparable<JsonEncoding>

public enum JsonEncoding
extends Enum<JsonEncoding>

Enumeration that defines legal encodings that can be used for JSON content, based on list of allowed encodings from JSON specification.

Note: if application want to explicitly disregard Encoding limitations (to read in JSON encoded using an encoding not listed as allowed), they can use Reader / Writer instances as input

Method Detail

values

public static JsonEncoding[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (JsonEncoding c : JsonEncoding.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static JsonEncoding valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getJavaName

public String getJavaName()

Method for accessing encoding name that JDK will support.

Returns:

Matching encoding name that JDK will support.

isBigEndian

public boolean isBigEndian()

Whether encoding is big-endian (if encoding supports such notion). If no such distinction is made (as is the case for UTF8), return value is undefined.

Returns:

True for big-endian encodings; false for little-endian (or if not applicable)
