枚举常量详细资料

TRANSFORM_ALL

public static final StateSnapshotTransformer.CollectionStateSnapshotTransformer.TransformStrategy TRANSFORM_ALL

Transform all entries.

STOP_ON_FIRST_INCLUDED

public static final StateSnapshotTransformer.CollectionStateSnapshotTransformer.TransformStrategy STOP_ON_FIRST_INCLUDED

Skip first null entries.

While traversing collection entries, as optimisation, stops transforming if encounters first non-null included entry and returns it plus the rest untouched.

方法详细资料

values

public static StateSnapshotTransformer.CollectionStateSnapshotTransformer.TransformStrategy[] 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 (StateSnapshotTransformer.CollectionStateSnapshotTransformer.TransformStrategy c : StateSnapshotTransformer.CollectionStateSnapshotTransformer.TransformStrategy.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 StateSnapshotTransformer.CollectionStateSnapshotTransformer.TransformStrategy 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
