枚举常量详细资料

DEFAULT

public static final LongSerializationPolicy DEFAULT

This is the "default" serialization policy that will output a long object as a JSON number. For example, assume an object has a long field named "f" then the serialized output would be: {"f":123}.

STRING

public static final LongSerializationPolicy STRING

Serializes a long value as a quoted string. For example, assume an object has a long field named "f" then the serialized output would be: {"f":"123"}.

方法详细资料

values

public static LongSerializationPolicy[] 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 (LongSerializationPolicy c : LongSerializationPolicy.values())
    System.out.println(c);

返回:

按照声明该枚举类型的常量的顺序返回的包含这些常量的数组

valueOf

public static LongSerializationPolicy 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:

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

NullPointerException - 如果参数为空值

serialize

public abstract JsonElement serialize(Long value)

Serialize this value using this serialization policy.

参数:

value - the long value to be serialized into a JsonElement

返回:

the serialized version of value
