Summary
Function: integer llGetListEntryType( list src, integer index );| 194 | Function ID |
| 0.0 | Forced Delay |
| 10.0 | Energy |
Returns an integer that is the type of the entry index in src.
| • list | src | – | List containing the element of interest. | |
| • integer | index | – | Index of the element of interest. |
index supports negative indexes.
If index describes a location not in src then TYPE_INVALID is returned.
Specification
| Index | Positive | Negative |
|---|---|---|
| First | 0
|
-length
|
| Last | length - 1
|
-1
|
Indexes
- Positive indexes count from the beginning, the first item being indexed as
0, the last as(length - 1).
- Negative indexes count from the far end, the first item being indexed as
-length, the last as-1.
| Type | Description | |
|---|---|---|
| TYPE_INTEGER | 1 | integer |
| TYPE_FLOAT | 2 | float |
| TYPE_STRING | 3 | string |
| TYPE_KEY | 4 | key |
| TYPE_VECTOR | 5 | vector |
| TYPE_ROTATION | 6 | rotation |
| TYPE_INVALID | 0 | none |
Caveats
- If index is out of bounds the script continues to execute without an error message.
- If a vector is stored in a list as "<7,5,0>" (as a string type, as opposed to <7,5,0> which is a vector type), its type will be returned as TYPE_STRING, not TYPE_VECTOR. The same applies for "1" being returned as a string instead of an integer, etc. There is no easy way to guess what the type should be from a string value. The users intent may not be obvious
Examples
Useful Snippets
This function has two primary uses: serializing a list to a string, debugging. <lsl>//A simple list serializer and deserializer. //This will round floats to 6 decimal places and not handle strings with embedded "
