Enum Content.CType

java.lang.Object

java.lang.Enum<Content.CType>

org.jdom2.Content.CType

All Implemented Interfaces:

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

Enclosing class:

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;
        ....
    }

Method Detail

values

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

Returns:

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

valueOf

public static Content.CType valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null
