要約
関数: integer llListFindListNext( list src, list test, list instance );index of the nth instance of test in src.を integer で返します。
| • list | src | – | what to search in (haystack) | |
| • list | test | – | what to search for (needles) | |
| • list | instance | – | which instance (needle) to return |
If test is not found in src, -1 is returned.
The index of the first entry in the list is 0
An expansion of llListFindList which adds an instance parameter to select the nth match to test parameter.
llListFindListNext(src, test, 0); is functionally equivalent to llListFindList(src, test);
Given a list like [ 'Resident', 'Alexia', 'Resident', 'Bob', 'Resident', 'Steve', 'Resident', 'Evil' ]
using a test of [ 'Resident' ] and an instance of 0, 1, 2, 3 would return indices of 0, 2, 4, and 6 respectively.
Selecting the 4th or greater instance will not be found and will return -1.
Reverse indexing is also supported. Using an instance of -1, -2, -3, -4 would respectively return 6, 4, 2, 0
And -5 and lower would again return -1
If test is found at the last index in src the positive index is returned (5th entry of 5 returns 4).
警告
- Strict type matching and case sensitivity is enforced.
- "1" != 1
- "1.0" != 1.0
- 1 != 1.0
- "a822ff2b-ff02-461d-b45d-dcd10a2de0c2" != (key)"a822ff2b-ff02-461d-b45d-dcd10a2de0c2"
- "Justice" != "justice"
- If test is an empty list the value returned is 0 rather than -1.
