```
short getShort(long index)
```
    Reads the short at the given index.
    
    Parameters:
    
    index - the index from which the float will be read
    
    Returns:
    
    the short at the given index
    
    Throws:
    
    IndexOutOfBoundsException - if index is negative or not smaller than the buffer size
  - setShort
```
ShortDataBuffer setShort(short value,
                         long index)
```
    Writes the given short into this buffer at the given index.
    
    Parameters:
    
    value - the short to be written
    
    index - the index at which the value will be written
    
    Returns:
    
    this buffer
    
    Throws:
    
    IndexOutOfBoundsException - if index is negative or not smaller than the buffer size
    
    ReadOnlyBufferException - if this buffer is read-only
  - read
```
default ShortDataBuffer read(short[] dst)
```
    Bulk get method, using short arrays.
    This method transfers values from this buffer into the given destination array. If there are fewer values in the buffer than are required to satisfy the request, that is, if dst.length > size(), then no values are transferred and a BufferUnderflowException is thrown.
    Otherwise, this method copies n = dst.length values from this buffer into the given array.
    
    Parameters:
    
    dst - the array into which values are to be written
    
    Returns:
    
    this buffer
    
    Throws:
    
    BufferUnderflowException - if there are not enough values to copy from this buffer
  - read
```
ShortDataBuffer read(short[] dst,
                     int offset,
                     int length)
```
    Bulk get method, using short arrays.
    This method transfers values from this buffer into the given destination array. If there are fewer values in the buffer than are required to satisfy the request, that is, if length > size(), then no values are transferred and a BufferUnderflowException is thrown.
    Otherwise, this method copies n = length values from this buffer into the given array starting at the given offset.
    
    Parameters:
    
    dst - the array into which values are to be written
    
    offset - the offset within the array of the first value to be written; must be non-negative and no larger than dst.length
    
    length - the maximum number of values to be written to the given array; must be non-negative and no larger than dst.length - offset
    
    Returns:
    
    this buffer
    
    Throws:
    
    BufferUnderflowException - if there are fewer than length values remaining in this buffer
    
    IndexOutOfBoundsException - if the preconditions on the offset and length parameters do not hold
  - write
```
default ShortDataBuffer write(short[] src)
```
    Bulk put method, using short arrays.
    This method transfers the values in the given source array into this buffer. If there are more values in the source array than in this buffer, that is, if src.length > size(), then no values are transferred and a BufferOverflowException is thrown.
    Otherwise, this method copies n = src.length values from the given array.
    
    Parameters:
    
    src - the source array from which values are to be read
    
    Returns:
    
    this buffer
    
    Throws:
    
    BufferOverflowException - if there is insufficient space in this buffer for the values in the source array
    
    ReadOnlyBufferException - if this buffer is read-only
  - write
```
ShortDataBuffer write(short[] src,
                      int offset,
                      int length)
```
    Bulk put method, using short arrays.
    This method transfers the values in the given source array into this buffer. If there are more values in the source array than in this buffer, that is, if length > size(), then no values are transferred and a BufferOverflowException is thrown.
    Otherwise, this method copies n = length values from the given array into this buffer, starting at the given offset.
    
    Parameters:
    
    src - the source array from which values are to be read
    
    offset - the offset within the array of the first value to be read; must be non-negative and no larger than src.length
    
    length - the number of values to be read from the given array; must be non-negative and no larger than src.length - offset
    
    Returns:
    
    this buffer
    
    Throws:
    
    BufferOverflowException - if there is insufficient space in this buffer for the values in the source array
    
    IndexOutOfBoundsException - if the preconditions on the offset and length parameters do not hold
    
    ReadOnlyBufferException - if this buffer is read-only
  - getObject
```
default Short getObject(long index)
```
    Description copied from interface: DataBuffer
    
    Reads the value at the given index. Important: Usage of this method should be limited to buffers of non-primitive types or when the data type is not deterministically known by the caller. In any other case, prefer the usage of its primitive variant which will significantly improve performances (e.g. IntDataBuffer.getInt(idx)
    
    Specified by:
    
    getObject in interface DataBuffer<Short>
    
    Parameters:
    
    index - the index from which the float will be read
    
    Returns:
    
    the value at the given index
  - setObject
```
default ShortDataBuffer setObject(Short value,
                                  long index)
```
    Description copied from interface: DataBuffer
    
    Writes the given value into this buffer at the given index. Important: Usage of this method should be limited to buffers of non-primitive types or when the data type is not deterministically known by the caller. In any other case, prefer the usage of its primitive variant which will significantly improve performances (e.g. IntDataBuffer.setInt(idx)
    
    Specified by:
    
    setObject in interface DataBuffer<Short>
    
    Parameters:
    
    value - the value to be written
    
    index - the index at which the value will be written
    
    Returns:
    
    this buffer
  - copyTo
```
ShortDataBuffer copyTo(DataBuffer<Short> dst,
                       long size)
```
    Description copied from interface: DataBuffer
    
    Write the references of the objects in the source array into this buffer.
    If there are more values to copy than the destination buffer size, i.e. size > dst.size(), then no values are transferred and a BufferOverflowException is thrown. On the other hand, if there are more values to copy that the source buffer size, i.e. > src.size(), then a BufferUnderfloatException is thrown.
    Otherwise, this method copies n = size values from this buffer into the destination buffer.
    
    Specified by:
    
    copyTo in interface DataBuffer<Short>
    
    Parameters:
    
    dst - the destination buffer into which values are copied; must not be this buffer
    
    size - number of values to copy to the destination buffer
    
    Returns:
    
    this buffer
  - offset
```
default ShortDataBuffer offset(long index)
```
    Description copied from interface: DataBuffer
    
    Creates a new buffer whose content is a shared subsequence of this buffer's content, starting at the given index.
    The index must not be greater than this buffer size. Changes to this buffer's content will be visible in the new buffer and vice versa. The new buffer will be read-only if, and only if, this buffer is read-only.
    This call is equivalent to slice(index, size() - index)
    
    Specified by:
    
    offset in interface DataBuffer<Short>
    
    Parameters:
    
    index - index of the first value of the new buffer created, must not be greater than size()
    
    Returns:
    
    the new buffer
  - narrow
```
default ShortDataBuffer narrow(long size)
```
    Description copied from interface: DataBuffer
    
    Creates a new buffer whose content is a shared subsequence of this buffer's content, whose size is set to the given value.
    The new size must not be greater than this buffer size. Changes to this buffer's content will be visible in the new buffer and vice versa. The new buffer will be read-only if, and only if, this buffer is read-only.
    This call is equivalent to slice(0, size)
    
    Specified by:
    
    narrow in interface DataBuffer<Short>
    
    Parameters:
    
    size - size of this new buffer
    
    Returns:
    
    the new buffer
  - slice
```
ShortDataBuffer slice(long index,
                      long size)
```
    Description copied from interface: DataBuffer
    
    Creates a new buffer whose content is a shared subsequence of this buffer's content, starting at the given index and of the given size.
    The index plus the new size must not be greater than this buffer size. Changes to this buffer's content will be visible in the new buffer and vice versa. The new buffer will be read-only if, and only if, this buffer is read-only.
    
    Specified by:
    
    slice in interface DataBuffer<Short>
    
    Parameters:
    
    index - index of the first value of the new buffer created
    
    size - size of this new buffer, must not be greater than size()
    
    Returns:
    
    the new buffer
  - window
```
default DataBufferWindow<ShortDataBuffer> window(long size)
```
    Description copied from interface: DataBuffer
    Creates a DataBufferWindow that provides a partial view of this buffer.
    The created window has a fixed size and can "slide" along this buffer to provide different views of the data without allocating a new buffer instance, like DataBuffer.offset(long) does. This improves overall performance when this operation is repeated frequently. For example:
```
 IntDataBuffer bufferA = DataBuffers.ofInts(1024);
 // ... init buffer data
 IntDataBuffer bufferB = DataBuffers.ofInts(1, 2, 3, 4);

 // Return the index of the first occurrence of bufferB in bufferA using a sliding window
 DataBufferWindow<IntDataBuffer> windowA = bufferA.window(4);
 for (int i = 0; i < bufferA.size() - bufferB.size(); ++i) {
     if (windowA.slideTo(i).buffer().equals(bufferB)) {
         return i;
     }
 }
 
```
    The returned object is stateful and is not thread-safe.
    Specified by:
    
    window in interface DataBuffer<Short>
    
    Parameters:
    
    size - size of the window
    
    Returns:
    
    a new window that starts at the index 0 of this buffer
