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。

implies

public boolean implies(FsAction that)

Return true if this action implies that action.

参数:

that -

and

public FsAction and(FsAction that)

AND operation.

or

public FsAction or(FsAction that)

OR operation.

not

public FsAction not()

NOT operation.
