## Summary

| ### Enum Values |
|---|---|
| `https://developer.android.com/reference/androidx/room/Transactor.SQLiteTransactionType#DEFERRED` | The transaction mode that does not start the actual transaction until the database is accessed, may it be a read or a write. |
| `https://developer.android.com/reference/androidx/room/Transactor.SQLiteTransactionType#EXCLUSIVE` | The transaction mode that immediately starts a write transaction and locks the database preventing others from accessing it. |
| `https://developer.android.com/reference/androidx/room/Transactor.SQLiteTransactionType#IMMEDIATE` | The transaction mode that immediately starts a write transaction. |

| ### Public methods |
|---|---|

| `static final @https://developer.android.com/reference/androidx/annotation/NonNull Transactor.SQLiteTransactionType[]` | `https://developer.android.com/reference/androidx/room/Transactor.SQLiteTransactionType#values()()` Returns an array containing the constants of this enum type, in the order they're declared. |

## Enum Values

### DEFERRED

```
Transactor.SQLiteTransactionType Transactor.SQLiteTransactionType.DEFERRED
```

The transaction mode that does not start the actual transaction until the database is accessed, may it be a read or a write.

### EXCLUSIVE

```
Transactor.SQLiteTransactionType Transactor.SQLiteTransactionType.EXCLUSIVE
```

The transaction mode that immediately starts a write transaction and locks the database preventing others from accessing it.

### IMMEDIATE

```
Transactor.SQLiteTransactionType Transactor.SQLiteTransactionType.IMMEDIATE
```

The transaction mode that immediately starts a write transaction.

## Public methods

### getEntries

```
public final @NonNull EnumEntries<@NonNull Transactor.SQLiteTransactionType> getEntries()
```

Returns an immutable `https://kotlinlang.org/api/core/kotlin-stdlib/kotlin.enums/-enum-entries/index.html` list containing the constants of this enum type, in the order they're declared.

### valueOf

Added in [2.7.0](https://developer.android.com/jetpack/androidx/releases/room#2.7.0)

```
public static final @NonNull Transactor.SQLiteTransactionType valueOf(@NonNull String value)
```

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

| Throws |
|---|---|
| `https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-illegal-argument-exception/index.html` | if this enum type has no constant with the specified name |

### values

Added in [2.7.0](https://developer.android.com/jetpack/androidx/releases/room#2.7.0)

```
public static final @NonNull Transactor.SQLiteTransactionType[] values()
```

Returns an array containing the constants of this enum type, in the order they're declared.

This method may be used to iterate over the constants.

The function returns a new instance of the array on every call. The array could be mutated, so working with it may also require defensive copying. Consider using `entries` property as a more efficient alternative returning an immutable list of enum entries.
