### XXHash64 Constructor

Source: https://www.javadoc.io/doc/org.lz4/lz4-java/1.8.0/net/jpountz/xxhash/XXHash64.html

The default constructor for the XXHash64 class.

```java
public XXHash64() {
}
```

--------------------------------

### ToString Method

Source: https://www.javadoc.io/doc/org.lz4/lz4-java/1.8.0/net/jpountz/xxhash/XXHash64.html

Returns a string representation of the XXHash64 object. This method overrides the default toString method from the Object class.

```java
public java.lang.String toString()
```

### hash(byte[] buf, int off, int len, long seed)

Source: https://www.javadoc.io/doc/org.lz4/lz4-java/1.8.0/net/jpountz/xxhash/XXHash64.html

Computes the 64-bits hash of a byte array slice using a specified seed. This method is abstract and intended to be implemented by subclasses.

```APIDOC
## hash(byte[] buf, int off, int len, long seed)

### Description
Computes the 64-bits hash of `buf[off:off+len]` using seed `seed`.

### Method
abstract long

### Parameters
#### Path Parameters
- **buf** (byte[]) - the input data
- **off** (int) - the start offset in buf
- **len** (int) - the number of bytes to hash
- **seed** (long) - the seed to use

### Returns
- **long** - the hash value
```

--------------------------------

### hash(ByteBuffer buf, int off, int len, long seed)

Source: https://www.javadoc.io/doc/org.lz4/lz4-java/1.8.0/net/jpountz/xxhash/XXHash64.html

Computes the hash of a given slice of a ByteBuffer using a specified seed. The buffer's position and limit remain unmodified after this operation.

```APIDOC
## hash(ByteBuffer buf, int off, int len, long seed)

### Description
Computes the hash of the given slice of the `ByteBuffer`. `position` and `limit` are not modified.

### Method
abstract long

### Parameters
#### Path Parameters
- **buf** (ByteBuffer) - the input data
- **off** (int) - the start offset in buf
- **len** (int) - the number of bytes to hash
- **seed** (long) - the seed to use

### Returns
- **long** - the hash value
```

--------------------------------

### Hash Byte Array

Source: https://www.javadoc.io/doc/org.lz4/lz4-java/1.8.0/net/jpountz/xxhash/XXHash64.html

Computes the 64-bit hash of a byte array slice using a seed. The input data, offset, length, and seed are specified.

```java
public abstract long hash(byte[] buf,
        int off,
        int len,
        long seed)
```

--------------------------------

### hash(ByteBuffer buf, long seed)

Source: https://www.javadoc.io/doc/org.lz4/lz4-java/1.8.0/net/jpountz/xxhash/XXHash64.html

Computes the hash of a given ByteBuffer using a specified seed. The buffer's position is updated to reflect the bytes that have been read.

```APIDOC
## hash(ByteBuffer buf, long seed)

### Description
Computes the hash of the given `ByteBuffer`. The `position` is moved in order to reflect bytes which have been read.

### Method
final long

### Parameters
#### Path Parameters
- **buf** (ByteBuffer) - the input data
- **seed** (long) - the seed to use

### Returns
- **long** - the hash value
```

--------------------------------

### Hash ByteBuffer

Source: https://www.javadoc.io/doc/org.lz4/lz4-java/1.8.0/net/jpountz/xxhash/XXHash64.html

Computes the hash of a given ByteBuffer. The position of the ByteBuffer is updated to reflect the bytes that have been read.

```java
public final long hash(java.nio.ByteBuffer buf,
        long seed)
```

--------------------------------

### Hash ByteBuffer Slice

Source: https://www.javadoc.io/doc/org.lz4/lz4-java/1.8.0/net/jpountz/xxhash/XXHash64.html

Computes the hash of a given slice of a ByteBuffer. The position and limit of the ByteBuffer are not modified by this method.

```java
public abstract long hash(java.nio.ByteBuffer buf,
        int off,
        int len,
        long seed)
```
