# Binding variables

Depending on the extension point, some variables are automatically made available inside the script. These are called *binding variables*.

Some binding variables are available to all scripts; others are available only to specific extension points. For example, extension points related to quotes automatically include a variable named **salesItemsTree**, which represents the quote's data. Scripts can use this variable to query information or make changes to a quote and its sales items.

## Common binding variables

The following table lists binding variables available to each [extension point](/main/docs/about-extension-points).

| Variable name | Class | Description |
| --- | --- | --- |
| dbLookupTable | GroovyLookupTable | Accesses Lookup Tables, if any, that the script can access. |
| groovyCtxUtil | GroovyCtxUtil | Utility class for ad-hoc data access. |
| groovyLogger | GroovyLogger | Use to log into a log file and display notifications in the GUI. |
| sessionLanguage | String | Current session's language code. |
| userInfo | UserInfo | Current user's basic information. This variable is null if the script is not triggered during a particular user's session, such as when triggered by a scheduled system task. |
| curencyCollection | CurrencyCollection | Collection that stores all currency information in the Plain Old Java Object (POJO) format. |
| uomCollection | UnitOfMeasureCollection | Stores all unit of measure information in the POJO format. |

For details about the classes listed in this table, including available methods, fields, and method signatures, read the [Zilliant Groovy API reference](/main/docs/groovy-api-reference).

## Query a script for available binding variables

You can query a script for a list of its available binding variables.

For example, the following script obtains the classes and names of all available binding variables and outputs the result to a notification message.

```groovy
def sb = new StringBuilder();
binding.variables.each {
    sb.append('(' + it.value.getClass().getName() + ') ')
        .append(it.key)
        .append("\n");
}
groovyLogger.notifyInfo(sb.toString());
```
