枚举 CircularReferenceMatchingMode

java.lang.Object

java.lang.Enum<CircularReferenceMatchingMode>

com.fr.common.diff.circular.CircularReferenceMatchingMode

所有已实现的接口:

java.io.Serializable, java.lang.Comparable<CircularReferenceMatchingMode>

public enum CircularReferenceMatchingMode
extends java.lang.Enum<CircularReferenceMatchingMode>

Defines how the CircularReferenceDetector compares object instances. The default is EQUALITY_OPERATOR and this should be sufficient in mose cases. However, you may be dealing with an object model that returns copies of its properties, instead of reusing the exact same instance. In this cases it would be easy to end up in infinite loops, as the default circular reference detection would not be able to detect this. In those cases you should switch to the EQUALS_METHOD mode. The trade-off is, that this renders you unable to nest equal but different objects.

枚举常量详细资料

EQUALITY_OPERATOR

public static final CircularReferenceMatchingMode EQUALITY_OPERATOR

Compares objects using the == operator.

EQUALS_METHOD

Compares objects using Object.equals(Object).

方法详细资料

values

public static CircularReferenceMatchingMode[] 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 (CircularReferenceMatchingMode c : CircularReferenceMatchingMode.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 CircularReferenceMatchingMode 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
