IRangeTOverlaps Method |
Returns true if the given range is partially contained
within this range.
Namespace: InnerDrive.Core
Assembly: InnerDrive.Core (in InnerDrive.Core.dll) Version: 5.0.8475.0
SyntaxC#
bool Overlaps( IRange<T>? value )
Parameters
Return Value
Booleantrue if the range is partially contained within this range.
Remarks
A range overlaps another range when the any part of one range is contained
within the other.
| Range A | Range B | A.Overlaps(B)? |
|---|---|---|
| 23456 | 012 | * |
| 23456 | 123 | true |
| 23456 | 23456 | true |
| 23456 | 567 | true |
| 23456 | 678 | * |
| 23456 | 789 | false |
* The behavior of Overlaps depends on whether the ranges are inclusive. Also, the results of RangeA.Overlaps(RangeB) and RangeB.Overlaps(RangeA) must always return the same value. Therefore, the following shows the behavior of two adjacent ranges. Assume RangeA = { 3, 4, 5 } and RangeB = { 5, 6, 7 }.
| RangeA.IsUpperInclusive | RangeB.IsLowerInclusive | A.Overlaps(B)? |
|---|---|---|
| true | true | true |
| true | false | false |
| false | true | false |
| false | false | false |
Orthogonal ranges always overlap, regardless of their IsLowerInclusive and IsUpperInclusive values.
