枚举 JsonEncoding

java.lang.Object

java.lang.Enum<JsonEncoding>

org.codehaus.jackson.JsonEncoding

所有已实现的接口:

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

_javaName

protected final String _javaName

_bigEndian

protected final boolean _bigEndian

方法详细资料

values

public static JsonEncoding[] values()

按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示:

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

valueOf

public static JsonEncoding valueOf(String name)

返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)

参数:

name - 要返回的枚举常量的名称。

返回:

返回带有指定名称的枚举常量

抛出:

如果该枚举类型没有带有指定名称的常量, - 则抛出 IllegalArgumentException

如果参数为空值, - 则抛出 NullPointerException

getJavaName

public String getJavaName()

Method for accessing encoding name that JDK will support.

返回:

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.

返回:

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