Fetches drafts. Supports filtering and sorting.

Typical usage:

```
var draftSelector = AdsApp.drafts()
    .withCondition("BaseCampaignId = 123456789")
    .orderBy("DraftName ASC");

var draftIterator = draftSelector.get();
while (draftIterator.hasNext()) {
  var draft = draftIterator.next();
}
```

## `get()`

Fetches the requested drafts and returns an iterator.

### Return values:

| Type | Description |
|---|---|
| `AdsApp.DraftIterator` | Iterator of the requested drafts. |

## `orderBy(orderBy)`

Specifies the ordering of the resulting entities. `orderBy` parameter can have one of the following forms:

- `orderBy("campaign_draft.name")` - orders results by draft name, in ascending order.
- `orderBy("campaign_draft.base_campaign ASC")` - orders results by base campaign resource name, in ascending order.
- `orderBy("campaign_draft.draft_id DESC")` - orders results by draft id, in descending order.

See [DraftSelector.withCondition(String)](https://developers.google.com/google-ads/scripts/docs/reference/adsapp/adsapp_draftselector.md.txt#withCondition_condition)
for enumeration of columns that can be used.

`orderBy()` may be called multiple times. Consider the
following example:

```
selector = selector.orderBy("campaign_draft.base_campaign ASC")
    .orderBy("campaign_draft.name");
```

The results will be ordered by campaign_draft.base_campaign in ascending
order. Results with equal campaign_draft.base_campaign values will be
ordered by campaign_draft.name in ascending order.

### Arguments:

| Name | Type | Description |
|---|---|---|
| orderBy | `String` | Ordering to apply. |

### Return values:

| Type | Description |
|---|---|
| `AdsApp.DraftSelector` | The selector with ordering applied. |

## `withCondition(condition)`

Adds the specified condition to the selector in order to narrow down the results.

Multiple conditions may be added to the same selector:

```
selector = selector
    .withCondition("BaseCampaignId = 123456789")
    .withCondition("DraftStatus = DRAFTED");
```
All specified conditions are `AND`-ed together. The above example will retrieve drafts with base campaign id 123456789 and status DRAFTED.

The parameter to be passed into this method must be of the following
form:

```
"COLUMN_NAME OPERATOR VALUE"
```

#### Operators

The operator that can be used in a condition depends on the type of column.

- For `Long` columns (e.g. campaign_draft.draft_id): **```
  < <= > >= = !=
  ```**
- For `String` columns (e.g. campaign_draft.name): **```
  = != (NOT) (LIKE | CONTAINS | REGEXP_MATCH)
  ```**
- For `Enumeration` columns (ones that can only take one value from a predefined list, such as campaign_draft.status) and `Boolean` columns: **```
  = != IN () NOT IN ()
  ```**

Conditions using `IN` and `NOT IN` operators look as follows:

```
withCondition("ColumnName IN (Value1, Value2)")
```

#### Columns

All column names are case-sensitive, and so are all values of enumerated
columns (such as DraftStatus).

| Column | Type | Example |
|---|---|---|
| campaign_draft.name | String | `withCondition("campaign_draft.name CONTAINS 'draft_'")` |
| campaign_draft.status | Enumeration: `DRAFTED`, `APPLIED`, `APPLYING`, `REMOVED`, `UNABLE_TO_APPLY` | `withCondition("campaign_draft.status = DRAFTED")` |
| campaign_draft.base_campaign | String | `withCondition("campaign_draft.base_campaign = 'customers/1234567890/campaigns/123'")`. The value is a campaign resource name. |
| campaign_draft.draft_id | Long | `withCondition("campaign_draft.draft_id = 123456789")` |
| campaign_draft.has_experiment_running | Boolean | `withCondition("campaign_draft.has_experiment_running = true")` |

### Arguments:

| Name | Type | Description |
|---|---|---|
| condition | `String` | Condition to add to the selector. |

### Return values:

| Type | Description |
|---|---|
| `AdsApp.DraftSelector` | The selector with the condition applied. |

## `withIds(ids)`

Restricts this selector to return only drafts with the given draft IDs.

All drafts are uniquely identified by the combination
of their
base campaign ID and draft ID. The IDs for this selector are
thus represented as two-element arrays, with the first element being the
base campaign ID and the second being the draft ID:

```
var draftIds = [
  ['12345', '987987'],
  ['23456', '876876'],
  ['34567', '765765'],
];
selector = selector.withIds(draftIds);
```

The resulting selector can be further refined by applying additional
conditions to it. The ID-based condition will then be AND-ed together with
all the other conditions, including any other ID-based conditions. So, for
instance, the following selector:

```
var ids1 = [
  ['12345', '987987'],
  ['23456', '876876'],
  ['34567', '765765'],
];
var ids2 = [
  ['34567', '765765'],
  ['45678', '654654'],
  ['56789', '543543'],
];
AdsApp.drafts()
   .withIds(ids1)
   .withIds(ids2);
```
will only get the draft with ID `['34567',
'765765']`, since it would be the only draft that satisfies both ID conditions.

### Arguments:

| Name | Type | Description |
|---|---|---|
| ids | `Object[][]` | Array of draft IDs. |

### Return values:

| Type | Description |
|---|---|
| `AdsApp.DraftSelector` | The selector restricted to the given IDs. |

## `withLimit(limit)`

Specifies limit for the selector to use. For instance, `withLimit(50)` returns only the first 50 entities.

### Arguments:

| Name | Type | Description |
|---|---|---|
| limit | `int` | How many entities to return. |

### Return values:

| Type | Description |
|---|---|
| `AdsApp.DraftSelector` | The selector with limit applied. |

## `withResourceNames(resourceNames)`

Restricts this selector to return only drafts with the given Google Ads API resource names.

```
const draftResourceNames = [
  'customers/1234567890/campaignDrafts/111~222',
  'customers/1234567890/campaignDrafts/111~333',
  'customers/1234567890/campaignDrafts/444~555',
];
selector = selector.withResourceNames(draftResourceNames);
```

The resulting selector can be further refined by applying additional
conditions to it. The resource name condition will then be AND-ed together
with all the other conditions.

The selector can only support up to 10,000 resource names. If more than
10,000 resource names are specified, the corresponding get() call will fail
with a runtime error.

### Arguments:

| Name | Type | Description |
|---|---|---|
| resourceNames | `String[]` | Array of draft resource names. |

### Return values:

| Type | Description |
|---|---|
| `AdsApp.DraftSelector` | The selector restricted to the given resource names. |
