class:ShortBuffer [CHANGED]
  • All Implemented Interfaces:
    Comparable<ShortBuffer> 

    public abstract class ShortBuffer
extends Buffer
implements Comparable<ShortBuffer>
    A short buffer.

    This class defines four categories of operations upon short buffers:

    • Absolute and relative get and put methods that read and write single shorts;

    • Relative bulk get methods that transfer contiguous sequences of shorts from this buffer into an array; and

    • Relative bulk put methods that transfer contiguous sequences of shorts from a short array or some other short buffer into this buffer; and

    • MethodsA method for compacting, duplicating, andslicing a short buffer.

    Short buffers can be created either by allocation, which allocates space for the buffer's content, by wrapping an existing short array into a buffer, or by creating a view of an existing byte buffer.

    Like a byte buffer, a short buffer is either direct or non-direct . A short buffer created via the wrap methods of this class will be non-direct. A short buffer created as a view of a byte buffer will be direct if, and only if, the byte buffer itself is direct. Whether or not a short buffer is direct may be determined by invoking the isDirect method.

    Methods in this class that do not otherwise have a value to return are specified to return the buffer upon which they are invoked. This allows method invocations to be chained.

    This method transfers the shorts remaining in the given source buffer into this buffer. If there are more shorts remaining in the source buffer than in this buffer, that is, if src.remaining() > remaining(), then no shorts are transferred and a BufferOverflowException is thrown.

    Otherwise, this method copies n = src.remaining() shorts from the given buffer into this buffer, starting at each buffer's current position. The positions of both buffers are then incremented by n.

    In other words, an invocation of this method of the form dst.put(src) has exactly the same effect as the loop

         while (src.hasRemaining())
         dst.put(src.get());
    except that it first checks that there is sufficient space in this buffer and it is potentially much more efficient.

                       int length)
    Relative bulk put method  (optional operation) .

    This method transfers shorts into this buffer from the given source array. If there are more shorts to be copied from the array than remain in this buffer, that is, if length > remaining(), then no shorts are transferred and a BufferOverflowException is thrown.

    Otherwise, this method copies length shorts from the given array into this buffer, starting at the given offset in the array and at the current position of this buffer. The position of this buffer is then incremented by length.

    In other words, an invocation of this method of the form dst.put(src, off, len) has exactly the same effect as the loop

    
     for (int i = off; i < off + len; i++)
         dst.put(a[i]);

    This buffer
    Throws:

    reset in class Buffer
    Returns:
    This buffer
    Since:
    9

method:clear() [ADDED]

  • clear 

    public final ShortBuffer clear()
    Clears this buffer. The position is set to zero, the limit is set to the capacity, and the mark is discarded.

    Invoke this method before using a sequence of channel-read or put operations to fill this buffer. For example: 

     
buf.clear();     // Prepare buffer for reading
 in.read(buf);    // Read data

    This method does not actually erase the data in the buffer, but it is named as if it did because it will most often be used in situations in which that might as well be the case.

    Overrides:
    clear in class Buffer
    Returns:
    This buffer
    Since:
    9

method:flip() [ADDED]

  • flip 

    public final ShortBuffer flip()
    Flips this buffer. The limit is set to the current position and then the position is set to zero. If the mark is defined then it is discarded.

    After a sequence of channel-read or put operations, invoke this method to prepare for a sequence of channel-write or relative get operations. For example: 

     
buf.put(magic);    // Prepend header
 in.read(buf);      // Read data into rest of buffer
 buf.flip();        // Flip buffer
 out.write(buf);    // Write header + data to channel

    This method is often used in conjunction with the compact method when transferring data from one place to another.

    Overrides:
    flip in class Buffer
    Returns:
    This buffer
    Since:
    9

method:rewind() [ADDED]

  • rewind 

    public final ShortBuffer rewind()
    Rewinds this buffer. The position is set to zero and the mark is discarded.

    Invoke this method before a sequence of channel-write or get operations, assuming that the limit has already been set appropriately. For example: 

     
out.write(buf);    // Write remaining data
 buf.rewind();      // Rewind buffer
 buf.get(array);    // Copy data into array
    Overrides:
    rewind in class Buffer
    Returns:
    This buffer
    Since:
    9

method:compact() [NONE]

  • compact

    public abstract ShortBuffer compact()
    Compacts this buffer  (optional operation) .

    The shorts between the buffer's current position and its limit, if any, are copied to the beginning of the buffer. That is, the short at index p = position() is copied to index zero, the short at index p + 1 is copied to index one, and so forth until the short at index limit() - 1 is copied to index n = limit() - 1 - p. The buffer's position is then set to n+1 and its limit is set to its capacity. The mark, if defined, is discarded.

    The buffer's position is set to the number of shorts copied, rather than to zero, so that an invocation of this method can be followed immediately by an invocation of another relative put method.

    Returns:
    This buffer
    Throws:
    ReadOnlyBufferException - If this buffer is read-only

method:isDirect() [NONE]

  • isDirect

    public abstract boolean isDirect()
    Tells whether or not this short buffer is direct.
    Specified by:
    isDirect in class Buffer
    Returns:
    true if, and only if, this buffer is direct

method:toString() [NONE]

  • toString

    public String toString()
    Returns a string summarizing the state of this buffer.
    Overrides:
    toString in class Object
    Returns:
    A summary string

method:hashCode() [NONE]

  • hashCode

    public int hashCode()
    Returns the current hash code of this buffer.

    The hash code of a short buffer depends only upon its remaining elements; that is, upon the elements from position() up to, and including, the element at limit() - 1.

    Because buffer hash codes are content-dependent, it is inadvisable to use buffers as keys in hash maps or similar data structures unless it is known that their contents will not change.

    Overrides:
    hashCode in class Object
    Returns:
    The current hash code of this buffer
    See Also:
    Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)

method:equals(java.lang.Object) [NONE]

  • equals

    public boolean equals(Object ob)
    Tells whether or not this buffer is equal to another object.

    Two short buffers are equal if, and only if,

    1. They have the same element type,

    2. They have the same number of remaining elements, and

    3. The two sequences of remaining elements, considered independently of their starting positions, are pointwise equal.

    A short buffer is not equal to any other type of object.

    Overrides:
    equals in class Object
    Parameters:
    ob - The object to which this buffer is to be compared
    Returns:
    true if, and only if, this buffer is equal to the given object
    See Also:
    Object.hashCode(), HashMap

method:compareTo(java.nio.ShortBuffer) [NONE]

  • compareTo

    public int compareTo(ShortBuffer that)
    Compares this buffer to another.

    Two short buffers are compared by comparing their sequences of remaining elements lexicographically, without regard to the starting position of each sequence within its corresponding buffer. Pairs of short elements are compared as if by invoking Short.compare(short,short).

    A short buffer is not comparable to any other type of object.

    Specified by:
    compareTo in interface Comparable<ShortBuffer>
    Parameters:
    that - the object to be compared.
    Returns:
    A negative integer, zero, or a positive integer as this buffer is less than, equal to, or greater than the given buffer

method:order() [NONE]

  • order

    public abstract ByteOrder order()
    Retrieves this buffer's byte order.

    The byte order of a short buffer created by allocation or by wrapping an existing short array is the native order of the underlying hardware. The byte order of a short buffer created as a view of a byte buffer is that of the byte buffer at the moment that the view is created.

    Returns:
    This buffer's byte order
