#### Functions
##### Length - len()
| Function | Description | Example |
|:-----------|:---------------------------------------------------------------------------------------------------------------- |:-------------------------- |
| `len` | Returns the length of the object/slice. Works only with the `[BODY]` placeholder. | `len([BODY].username) > 8`
| `pat` | Specifies that the string passed as parameter should be evaluated as a pattern. Works only with `==` and `!=`. | `[IP] == pat(192.168.*)`
Returns the length of the object/slice.
Example:
```
len([BODY].username) > 8
```
Works only with the `[BODY]` placeholder.
##### Pattern - pat()
Specifies that the string passed as parameter should be evaluated as a pattern.
Usage:
```
[IP] == pat(192.168.*)
```
Works only with `==` and `!=` comparators.
**NOTE**: Use patterns only when you need to. `[STATUS] == pat(2*)` is a lot more expensive than `[STATUS] < 300`.
