## Public constructors

### IkeIOException

Added in [API level 33](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public IkeIOException (IOException cause)
```

Constructs a new exception with the specified cause.

Callers are not generally expected to instantiate this object themselves, except for
testing. A reference is passed via `https://developer.android.com/reference/android/net/ipsec/ike/IkeSessionCallback` or `https://developer.android.com/reference/android/net/ipsec/ike/ChildSessionCallback`.

<br />

| Parameters ||
|---|---|
| `cause` | `IOException`: the cause (which is saved for later retrieval by the `https://developer.android.com/reference/android/net/ipsec/ike/exceptions/IkeIOException#getCause()` method). This value cannot be `null`. <br /> |

## Public methods

### getCause

Added in [API level 33](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public IOException getCause ()
```

Returns the cause of this IkeIOException.

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/io/IOException` | the cause of this IkeIOException. It might be a subclass of IOException that represents a specific type of I/O issue. For example, `https://developer.android.com/reference/java/net/UnknownHostException` and `https://developer.android.com/reference/android/net/ipsec/ike/exceptions/IkeTimeoutException`. This value cannot be `null`. <br /> |

### initCause

Added in [API level 33](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public Throwable initCause (Throwable cause)
```

Initializes the *cause* of this throwable to the specified value.
(The cause is the throwable that caused this throwable to get thrown.)

This method can be called at most once. It is generally called from
within the constructor, or immediately after creating the
throwable. If this throwable was created
with `https://developer.android.com/reference/java/lang/Throwable#Throwable(java.lang.Throwable)` or
`https://developer.android.com/reference/java/lang/Throwable#Throwable(java.lang.String,%20java.lang.Throwable)`, this method cannot be called
even once.

An example of using this method on a legacy throwable type
without other support for setting the cause is:

```
try {
    lowLevelOp();
} catch (LowLevelException le) {
    throw (HighLevelException)
          new HighLevelException().initCause(le); // Legacy constructor
}
```

<br />

<br />

| Parameters ||
|---|---|
| `cause` | `Throwable`: the cause (which is saved for later retrieval by the `https://developer.android.com/reference/android/net/ipsec/ike/exceptions/IkeIOException#getCause()` method). (A `null` value is permitted, and indicates that the cause is nonexistent or unknown.) <br /> |

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/lang/Throwable` | a reference to this `Throwable` instance. <br /> |
