*** ** * ** ***

Metadata describing an encryption pattern for the protected bytes in a subsample. An encryption pattern consists of a repeating sequence of crypto blocks comprised of a number of encrypted blocks followed by a number of unencrypted, or skipped, blocks.

## Summary

| ### Public constructors ||
|---|---|
| ` https://developer.android.com/reference/android/media/MediaCodec.CryptoInfo.Pattern#Pattern(int,%20int)(int blocksToEncrypt, int blocksToSkip) ` Construct a sample encryption pattern given the number of blocks to encrypt and skip in the pattern. |

| ### Public methods ||
|---|---|
| ` int` | ` https://developer.android.com/reference/android/media/MediaCodec.CryptoInfo.Pattern#getEncryptBlocks()() ` Return the number of blocks to encrypt in a sample encryption pattern. |
| ` int` | ` https://developer.android.com/reference/android/media/MediaCodec.CryptoInfo.Pattern#getSkipBlocks()() ` Return the number of blocks to skip in a sample encryption pattern. |
| ` void` | ` https://developer.android.com/reference/android/media/MediaCodec.CryptoInfo.Pattern#set(int,%20int)(int blocksToEncrypt, int blocksToSkip) ` Set the number of blocks to encrypt and skip in a sample encryption pattern. |

## Public constructors

### Pattern

Added in [API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public Pattern (int blocksToEncrypt, 
                int blocksToSkip)
```

Construct a sample encryption pattern given the number of blocks to encrypt and skip in the pattern. If both parameters are zero, pattern encryption is inoperative.

<br />

| Parameters ||
|---|---|
| `blocksToEncrypt` | `int` <br /> |
| `blocksToSkip` | `int` <br /> |

## Public methods

### getEncryptBlocks

Added in [API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int getEncryptBlocks ()
```

Return the number of blocks to encrypt in a sample encryption pattern.

<br />

| Returns ||
|---|---|
| `int` | <br /> |

### getSkipBlocks

Added in [API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int getSkipBlocks ()
```

Return the number of blocks to skip in a sample encryption pattern.

<br />

| Returns ||

### set

Added in [API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public void set (int blocksToEncrypt, 
                int blocksToSkip)
```

Set the number of blocks to encrypt and skip in a sample encryption pattern. If both parameters are zero, pattern encryption is inoperative.
