### Description

Provides methods for accessing collections.

### Syntax

```javascript
Collection
```

### Examples

The following example shows how to retrieve all application fields from the document's main text and do something with them afterwards:

```javascript
let fields = [];
TXTextControl.applicationFields.forEach((field, i, n) => {
   fields.push(field);
   if (i == (n - 1)) {
      console.log(`${fields.length} application fields retrieved!`);
      // Do something meaningful with the retrieved fields here...
   }
});


Possible console output after calling this code:

> 17 application fields retrieved!
```

The following example demonstrates `Collection` in a practical document-editing workflow. It provides methods for accessing collections.

```javascript
function onTxError(error) {
    console.error("TX Text Control error:", error.msg);
    error.handled = true;
}

function inspectCollection(s) {
    s.getCount(
        function(result) {
            console.log("get count result:", result);
        },
        onTxError
    );
}
```
