**Static system related constants and functions.**

## Functions


### `@System.getCurrentMemoryUsage()`


Gets the current memory usage of the underlying runtime environment in number of bytes.

```code
@System.getCurrentMemoryUsage(): int
```

##### Returns

| Type | Value |
| --- | ---  |
| `int` |  |




### `@System.getHost()`


Gets the host name of the system.

```code
@System.getHost(): string
```

##### Returns

| Type | Value |
| --- | ---  |
| `string` |  |




### `@System.getMachine()`

```code
@System.getMachine(): string
```

##### Returns

| Type | Value |
| --- | ---  |
| `string` |  |




### `@System.getMonotonicTime()`


Gets the system's monotonic clock in ticks, representing elapsed time since an unspecified starting point.

```code
@System.getMonotonicTime(): int
```

##### Returns

| Type | Value |
| --- | ---  |
| `int` |  |
| `float` |  |




### `@System.getPeakMemoryUsage()`


Gets the peak memory usage of the underlying runtime environment in number of bytes.

```code
@System.getPeakMemoryUsage(): int
```

##### Returns

| Type | Value |
| --- | ---  |

| `int` |  |




### `@System.listCommandLineArguments()`


Lists all command line arguments passed to the underlying runtime environment.

```code
@System.listCommandLineArguments(): object
```

##### Returns

| Type | Value |
| --- | ---  |
| `object` | [argument, ...] |




### `@System.sleep()`


Delays execution for a specific duration in number of seconds.

```code
@System.sleep(number $duration): void
```

##### Parameters
