All Implemented Interfaces:

Comparable<ShortBuffer>
```
public abstract class ShortBuffer
extends Buffer
implements Comparable<ShortBuffer>
```
A buffer of shorts.
A short buffer can be created in either of the following ways:
- Allocate a new short array and create a buffer based on it;
- Wrap an existing short array to create a new buffer;
- Use ByteBuffer.asShortBuffer to create a short buffer based on a byte buffer.

  - allocate
```
public static ShortBuffer allocate(int capacity)
```
    Creates a short buffer based on a newly allocated short array.
    
    Parameters:
    
    capacity - the capacity of the new buffer.
    
    Returns:
    
    the created short buffer.
    
    Throws:
    
    IllegalArgumentException - if capacity is less than zero.
  - wrap
```
public static ShortBuffer wrap(short[] array)
```
    Creates a new short buffer by wrapping the given short array.
    Calling this method has the same effect as wrap(array, 0, array.length).
    
    Parameters:
    
    array - the short array which the new buffer will be based on.
    
    Returns:
    
    the created short buffer.
  - wrap
```
public static ShortBuffer wrap(short[] array,
                               int start,
                               int shortCount)
```
    Creates a new short buffer by wrapping the given short array.
    The new buffer's position will be start, limit will be start + shortCount, capacity will be the length of the array.
    
    Parameters:
    
    array - the short array which the new buffer will be based on.
    
    start - the start index, must not be negative and not greater than array.length.
    
    shortCount - the length, must not be negative and not greater than array.length - start.
    
    Returns:
    
    the created short buffer.
    
    Throws:
    
    IndexOutOfBoundsException - if either start or shortCount is invalid.
  - array
```
public final short[] array()
```
    Description copied from class: Buffer
    
    Returns the array that backs this buffer (optional operation). The returned value is the actual array, not a copy, so modifications to the array write through to the buffer.
    Subclasses should override this method with a covariant return type to provide the exact type of the array.
    Use hasArray to ensure this method won't throw. (A separate call to isReadOnly is not necessary.)
    
    Specified by:
    
    array in class Buffer
    
    Returns:
    
    the array
  - arrayOffset
```
public final int arrayOffset()
```
    Description copied from class: Buffer
    
    Returns the offset into the array returned by array of the first element of the buffer (optional operation). The backing array (if there is one) is not necessarily the same size as the buffer, and position 0 in the buffer is not necessarily the 0th element in the array. Use buffer.array()[offset + buffer.arrayOffset() to access element offset in buffer.
    Use hasArray to ensure this method won't throw. (A separate call to isReadOnly is not necessary.)
    
    Specified by:
    
    arrayOffset in class Buffer
    
    Returns:
    
    the offset
  - asReadOnlyBuffer
```
public abstract ShortBuffer asReadOnlyBuffer()
```
    Returns a read-only buffer that shares its content with this buffer.
    The returned buffer is guaranteed to be a new instance, even if this buffer is read-only itself. The new buffer's position, limit, capacity and mark are the same as this buffer's.
    The new buffer shares its content with this buffer, which means this buffer's change of content will be visible to the new buffer. The two buffer's position, limit and mark are independent.
    
    Returns:
    
    a read-only version of this buffer.
  - position
```
public final ShortBuffer position(int newPosition)
```
    Sets the position of this buffer.
    If the mark is set and it is greater than the new position, then it is cleared.
    
    Overrides:
    
    position in class Buffer
    
    Parameters:
    
    newPosition - the new position, must be not negative and not greater than limit.
    
    Returns:
    
    this buffer.
  - limit
```
public final ShortBuffer limit(int newLimit)
```
    Sets the limit of this buffer.
    If the current position in the buffer is in excess of newLimit then, on returning from this call, it will have been adjusted to be equivalent to newLimit. If the mark is set and is greater than the new limit, then it is cleared.
    
    Overrides:
    
    limit in class Buffer
    
    Parameters:
    
    newLimit - the new limit, must not be negative and not greater than capacity.
    
    Returns:
    
    this buffer.
  - mark
```
public final ShortBuffer mark()
```
    Marks the current position, so that the position may return to this point later by calling reset().
    
    Overrides:
    
    mark in class Buffer
    
    Returns:
    
    this buffer.
  - reset
```
public final ShortBuffer reset()
```
    Resets the position of this buffer to the mark.
    
    Overrides:
    
    reset in class Buffer
    
    Returns:
    
    this buffer.
  - clear
```
public final ShortBuffer clear()
```
    Clears this buffer.
    While the content of this buffer is not changed, the following internal changes take place: the current position is reset back to the start of the buffer, the value of the buffer limit is made equal to the capacity and mark is cleared.
    
    Overrides:
    
    clear in class Buffer
    
    Returns:
    
    this buffer.
  - flip
```
public final ShortBuffer flip()
```
    Flips this buffer.
    The limit is set to the current position, then the position is set to zero, and the mark is cleared.
    The content of this buffer is not changed.
    
    Overrides:
    
    flip in class Buffer
    
    Returns:
    
    this buffer.
  - rewind
```
public final ShortBuffer rewind()
```
    Rewinds this buffer.
    The position is set to zero, and the mark is cleared. The content of this buffer is not changed.
    
    Overrides:
    
    rewind in class Buffer
    
    Returns:
    
    this buffer.
  - compact
```
public abstract ShortBuffer compact()
```
    Compacts this short buffer.
    The remaining shorts will be moved to the head of the buffer, starting from position zero. Then the position is set to remaining(); the limit is set to capacity; the mark is cleared.
    
    Returns:
    
    this buffer.
    
    Throws:
    
    ReadOnlyBufferException - if no changes may be made to the contents of this buffer.
  - compareTo
```
public int compareTo(ShortBuffer otherBuffer)
```
    Compare the remaining shorts of this buffer to another short buffer's remaining shorts.
    
    Specified by:
    
    compareTo in interface Comparable<ShortBuffer>
    
    Parameters:
    
    otherBuffer - another short buffer.
    
    Returns:
    
    a negative value if this is less than otherBuffer; 0 if this equals to otherBuffer; a positive value if this is greater than otherBuffer.
    
    Throws:
    
    ClassCastException - if otherBuffer is not a short buffer.
  - mismatch
```
public int mismatch(ShortBuffer that)
```
    Finds and returns the relative index of the first mismatch between this buffer and a given buffer. The index is relative to the position of each buffer and will be in the range of 0 (inclusive) up to the smaller of the remaining elements in each buffer (exclusive).
    If the two buffers share a common prefix then the returned index is the length of the common prefix and it follows that there is a mismatch between the two buffers at that index within the respective buffers. If one buffer is a proper prefix of the other then the returned index is the smaller of the remaining elements in each buffer, and it follows that the index is only valid for the buffer with the larger number of remaining elements. Otherwise, there is no mismatch.
    
    Parameters:
    
    that - The byte buffer to be tested for a mismatch with this buffer
    
    Returns:
    
    The relative index of the first mismatch between this and the given buffer, otherwise -1 if no mismatch.
    
    Since:
    
    11
  - duplicate
```
public abstract ShortBuffer duplicate()
```
    Returns a duplicated buffer that shares its content with this buffer.
    The duplicated buffer's position, limit, capacity and mark are the same as this buffer. The duplicated buffer's read-only property and byte order are the same as this buffer's.
    The new buffer shares its content with this buffer, which means either buffer's change of content will be visible to the other. The two buffers' position, limit and mark are independent.
    
    Specified by:
    
    duplicate in class Buffer
    
    Returns:
    
    The new buffer
  - equals
```
public boolean equals(Object other)
```
    Checks whether this short buffer is equal to another object.
    If other is not a short buffer then false is returned. Two short buffers are equal if and only if their remaining shorts are exactly the same. Position, limit, capacity and mark are not considered.
    
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    other - the object to compare with this short buffer.
    
    Returns:
    
    true if this short buffer is equal to other, false otherwise.

  - get
```
public ShortBuffer get(short[] dst)
```
    Reads shorts from the current position into the specified short array and increases the position by the number of shorts read.
    Calling this method has the same effect as get(dst, 0, dst.length).
    
    Parameters:
    
    dst - the destination short array.
    
    Returns:
    
    this buffer.
    
    Throws:

  - get
```
public ShortBuffer get(short[] dst,
                       int dstOffset,
                       int shortCount)
```
    Reads shorts from the current position into the specified short array, starting from the specified offset, and increases the position by the number of shorts read.
    
    Parameters:
    
    dst - the target short array.
    
    dstOffset - the offset of the short array, must not be negative and not greater than dst.length.

    index - the index, must not be negative and less than limit.
    
    Returns:
    
    a short at the specified index.
    
    Throws:
    
    IndexOutOfBoundsException - if index is invalid.
  - hasArray
```
public final boolean hasArray()
```
    Description copied from class: Buffer
    
    Returns true if array and arrayOffset won't throw. This method does not return true for buffers not backed by arrays because the other methods would throw UnsupportedOperationException, nor does it return true for buffers backed by read-only arrays, because the other methods would throw ReadOnlyBufferException.
    
    Specified by:
    
    hasArray in class Buffer
  - hashCode
```
public int hashCode()
```
    Calculates this buffer's hash code from the remaining chars. The position, limit, capacity and mark don't affect the hash code.

    the hash code calculated from the remaining shorts.
    
    See Also:
    
    Object.equals(java.lang.Object)
  - isDirect
```
public abstract boolean isDirect()
```
    Indicates whether this buffer is direct. A direct buffer will try its best to take advantage of native memory APIs and it may not stay in the Java heap, so it is not affected by garbage collection.
    A short buffer is direct if it is based on a byte buffer and the byte buffer is direct.
    
    Specified by:
    
    isDirect in class Buffer

  - put
```
public final ShortBuffer put(short[] src)
```
    Writes shorts from the given short array to the current position and increases the position by the number of shorts written.

    src - the source short array.
    
    Returns:
    
    this buffer.

    IndexOutOfBoundsException - if either srcOffset or shortCount is invalid.
    
    ReadOnlyBufferException - if no changes may be made to the contents of this buffer.
  - put
```
public ShortBuffer put(ShortBuffer src)
```
    Writes all the remaining shorts of the src short buffer to this buffer's current position, and increases both buffers' position by the number of shorts copied.
    
    Parameters:
    
    src - the source short buffer.
    
    Returns:
    
    this buffer.

```
    Returns a sliced buffer that shares its content with this buffer.
    The sliced buffer's capacity will be this buffer's remaining(), and its zero position will correspond to this buffer's current position. The new buffer's position will be 0, limit will be its capacity, and its mark is cleared. The new buffer's read-only property and byte order are same as this buffer's.
    The new buffer shares its content with this buffer, which means either buffer's change of content will be visible to the other. The two buffers' position, limit and mark are independent.
    
    Specified by:
    
    slice in class Buffer
    
    Returns:
