注解
使用 CreateSection 定义新节。 是 BitVector32.Section 进入 BitVector32 的窗口,由可包含 中指定的 CreateSection最大值的最小连续位数组成。 例如,最大值为 1 的节仅由 1 位组成,而最大值为 5 的节由 3 位组成。 可以创建 BitVector32.Section 最大值为 1 的 以用作布尔值,从而允许在同 BitVector32一 个 中存储整数和布尔值。
属性
Mask |
获取在 BitVector32 中隔离此节的掩码。 |
Offset |
获取从 BitVector32 的起始处开始的此节的偏移量。 |
方法
Equals(BitVector32+Section) |
确定指定 BitVector32.Section 对象是否与当前 BitVector32.Section 对象相同。 |
Equals(Object) |
确定指定对象是否与当前 BitVector32.Section 对象相同。 |
GetHashCode() |
用作当前 BitVector32.Section 的哈希函数,适合用在哈希算法和数据结构(如哈希表)中。 |
ToString() |
返回表示当前 BitVector32.Section 的字符串。 |
ToString(BitVector32+Section) |
返回表示指定的 BitVector32.Section 的字符串。 |
运算符
Equality(BitVector32+Section, BitVector32+Section) |
确定两个指定的 BitVector32.Section 对象是否相等。 |
Inequality(BitVector32+Section, BitVector32+Section) |
确定两个 BitVector32.Section 对象是否具有不同的值。 |
