Method Detail

slice

public ShortBuffer slice()
Description copied from class: ShortBuffer
Creates a new short buffer whose content is a shared subsequence of this buffer's content.

The content of the new buffer will start at this buffer's current position. Changes to this buffer's content will be visible in the new buffer, and vice versa; the two buffers' position, limit, and mark values will be independent.

The new buffer's position will be zero, its capacity and its limit will be the number of shorts remaining in this buffer, and its mark will be undefined. The new buffer will be direct if, and only if, this buffer is direct, and it will be read-only if, and only if, this buffer is read-only.

Overrides:
slice in class ByteBufferAsShortBufferB

duplicate

public ShortBuffer duplicate()
Description copied from class: ShortBuffer
Creates a new short buffer that shares this buffer's content.

The content of the new buffer will be that of this buffer. Changes to this buffer's content will be visible in the new buffer, and vice versa; the two buffers' position, limit, and mark values will be independent.

The new buffer's capacity, limit, position, and mark values will be identical to those of this buffer. The new buffer will be direct if, and only if, this buffer is direct, and it will be read-only if, and only if, this buffer is read-only.

Overrides:
duplicate in class ByteBufferAsShortBufferB

asReadOnlyBuffer

public ShortBuffer asReadOnlyBuffer()
Description copied from class: ShortBuffer
Creates a new, read-only short buffer that shares this buffer's content.

The content of the new buffer will be that of this buffer. Changes to this buffer's content will be visible in the new buffer; the new buffer itself, however, will be read-only and will not allow the shared content to be modified. The two buffers' position, limit, and mark values will be independent.

The new buffer's capacity, limit, position, and mark values will be identical to those of this buffer.

If this buffer is itself read-only then this method behaves in exactly the same way as the duplicate method.

Overrides:
asReadOnlyBuffer in class ByteBufferAsShortBufferB

put

public ShortBuffer put(short x)
Description copied from class: ShortBuffer
Relative put method  (optional operation).

Writes the given short into this buffer at the current position, and then increments the position.

Overrides:
put in class ByteBufferAsShortBufferB

put

public ShortBuffer put(int i,
                       short x)
Description copied from class: ShortBuffer
Absolute put method  (optional operation).

Writes the given short into this buffer at the given index.

Overrides:
put in class ByteBufferAsShortBufferB

compact

public ShortBuffer compact()
Description copied from class: ShortBuffer
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.

Overrides:
compact in class ByteBufferAsShortBufferB

isDirect

public boolean isDirect()
Description copied from class: ShortBuffer
Tells whether or not this short buffer is direct.

Overrides:
isDirect in class ByteBufferAsShortBufferB

isReadOnly

public boolean isReadOnly()
Description copied from class: Buffer
Tells whether or not this buffer is read-only.

Overrides:
isReadOnly in class ByteBufferAsShortBufferB

order

public ByteOrder order()
Description copied from class: ShortBuffer
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.

Overrides:
order in class ByteBufferAsShortBufferB

ix

protected int ix(int i)

get

public short get()
Description copied from class: ShortBuffer
Relative get method. Reads the short at this buffer's current position, and then increments the position.

Specified by:
get in class ShortBuffer
Returns:
The short at the buffer's current position

get

public short get(int i)
Description copied from class: ShortBuffer
Absolute get method. Reads the short at the given index.

Specified by:
get in class ShortBuffer
Parameters:
i - The index from which the short will be read
Returns:
The short at the given index
