Methods
clone
▸ clone(): KInterval
克隆当前区间,返回一个新对象。
Return the cloned object.

Defined in
api.d.ts:8866
contains
▸ contains(point
, includeEnds
, disTol?
): boolean
判断当前区间是否包含某个数值。
Check whether the interval contains a value.
Parameters
Name | Type | Description |
---|---|---|
point | number | 要检查的数值。 The value to check. |
includeEnds | boolean | 是否把当前区间当作是闭区间。 Whether take the interval as closed. |
disTol? | number | 用于判断包含关系的容差。如果没有给定则采用全局距离容差。 The tolerance used to check the value is containded by the interval. If it is not provided, global distance tolerance will be used. |
Returns
boolean
如果区间包含输入值,则返回真,否则为假。
True, if the interval contains the value, otherwise false.
Defined in
api.d.ts:8965
containsInterval
▸ containsInterval(interval
, includeEnds
, disTol?
): boolean
判断当前区间是否包含另外一个区间。
Check whether the current interval contains the other interval.
Parameters
Name | Type | Description |
---|---|---|
interval | KInterval | 是否被当前区间包含的另一个区间。 The other interval to be checked. |
includeEnds | boolean | 是否把两个区间当作是闭区间。 Whether take the two intervals as closed. |
disTol? | number | 用于判断包含关系的容差。如果没有给定则采用全局距离容差。 The tolerance used to check the value is containded by the interval. If it is not provided, global distance tolerance will be used. |
Returns
boolean
如果当前区间包含输入的区间,则返回真,否则为假。
True, if current interval contains the other interval, otherwise false.
Defined in
api.d.ts:8988
expanded

): KInterval
构建一个新的区间,起点和终点分别是当前区间起点和终点向外扩张给定距离。
Create a new interval whose start and end are expended by the given number.
Parameters
Name | Type | Description |
---|---|---|
length | number | 扩张距离。 The expand distance. |
Returns
