枚举 Content.CType

java.lang.Object

java.lang.Enum<Content.CType>

org.jdom2.Content.CType

所有已实现的接口:

java.io.Serializable, java.lang.Comparable<Content.CType>

封闭类:

Content

public static enum Content.CType
extends java.lang.Enum<Content.CType>

An enumeration useful for identifying content types without having to do

instanceof

type conditionals.

instanceof

is not a particularly safe way to test content in JDOM because CDATA extends Text ( a CDATA instance is an

instanceof

Text). This CType enumeration provides a direct and sure mechanism for identifying JDOM content. These can be used in switch-type statements too (which is much neater than chained if (instanceof) else if (instanceof) else .... expressions):

    switch(content.getCType()) {
        case Text :
             .....
             break; 
        case CDATA :
             .....
             break;
        ....
    }

方法详细资料

values

public static Content.CType[] 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 (Content.CType c : Content.CType.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 Content.CType valueOf(java.lang.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:

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

java.lang.NullPointerException - 如果参数为空值
