capacity - the capacity of the new buffer.IllegalArgumentException - if capacity is less than zero.public static ShortBuffer wrap(short[] array)
Calling this method has the same effect as
wrap(array, 0, array.length).
array - the short array which the new buffer will be based on.public static ShortBuffer wrap(short[] array, int start, int shortCount)
The new buffer's position will be start, limit will be
start + shortCount, capacity will be the length of the array.

array.length.shortCount - the length, must not be negative and not greater than
array.length - start.IndexOutOfBoundsException - if either start or shortCount is invalid.public final short[] array()
BufferSubclasses 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.)
public final int arrayOffset()
Bufferarray 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.)
arrayOffset in class Bufferpublic abstract ShortBuffer asReadOnlyBuffer()
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.
public final ShortBuffer position(int newPosition)
If the mark is set and it is greater than the new position, then it is cleared.
public final ShortBuffer limit(int newLimit)
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.
public final ShortBuffer mark()
reset().public final ShortBuffer reset()
mark.public final ShortBuffer clear()
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.
public final ShortBuffer flip()
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.
public final ShortBuffer rewind()
The position is set to zero, and the mark is cleared. The content of this buffer is not changed.
public abstract ShortBuffer compact()
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.
ReadOnlyBufferException - if no changes may be made to the contents of this buffer.public int compareTo(ShortBuffer otherBuffer)
compareTo in interface Comparable<ShortBuffer>otherBuffer - another short buffer.otherBuffer; 0 if
this equals to otherBuffer; a positive value if this is
greater than otherBuffer.ClassCastException - if otherBuffer is not a short buffer.public int mismatch(ShortBuffer that)
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.
that - The byte buffer to be tested for a mismatch with this bufferpublic abstract ShortBuffer duplicate()
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.
public boolean equals(Object other)
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.

Bufferarray 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.public int hashCode()
hashCode in class ObjectObject.equals(java.lang.Object)public abstract boolean isDirect()
A short buffer is direct if it is based on a byte buffer and the byte buffer is direct.
public abstract ByteOrder order()
If this buffer is not based on a byte buffer, then always return the platform's native byte order.

s - the short to write.BufferOverflowException - if position is equal or greater than limit.ReadOnlyBufferException - if no changes may be made to the contents of this buffer.public final ShortBuffer put(short[] src)

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.
