Method Detail

asReadOnlyBufferback to summary
public DoubleBuffer asReadOnlyBuffer()

Overrides java.nio.DirectDoubleBufferU.asReadOnlyBuffer.

Doc from java.nio.DoubleBuffer.asReadOnlyBuffer.

Creates a new, read-only double 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, mark values, and byte order 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.

compactback to summary
public DoubleBuffer compact()

Overrides java.nio.DirectDoubleBufferU.compact.

Doc from java.nio.DoubleBuffer.compact.

Compacts this buffer  (optional operation).

The doubles between the buffer's current position and its limit, if any, are copied to the beginning of the buffer. That is, the double at index p = position() is copied to index zero, the double at index p + 1 is copied to index one, and so forth until the double 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 doubles copied, rather than to zero, so that an invocation of this method can be followed immediately by an invocation of another relative put method.

duplicateback to summary
public DoubleBuffer duplicate()

Overrides java.nio.DirectDoubleBufferU.duplicate.

Doc from java.nio.DoubleBuffer.duplicate.

Creates a new double 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, mark values, and byte order 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.

isDirectback to summary
public boolean isDirect()

Overrides java.nio.DirectDoubleBufferU.isDirect.

Doc from java.nio.DoubleBuffer.isDirect.

Tells whether or not this double buffer is direct.

isReadOnlyback to summary
public boolean isReadOnly()

Overrides java.nio.DirectDoubleBufferU.isReadOnly.

Doc from java.nio.Buffer.isReadOnly.

Tells whether or not this buffer is read-only.

orderback to summary
public ByteOrder order()

Overrides java.nio.DirectDoubleBufferU.order.

Doc from java.nio.DoubleBuffer.order.

Retrieves this buffer's byte order.

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

putback to summary
public DoubleBuffer put(double x)

Overrides java.nio.DirectDoubleBufferU.put.

Doc from java.nio.DoubleBuffer.put.

Relative put method  (optional operation).

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

putback to summary
public DoubleBuffer put(int i, double x)

Overrides java.nio.DirectDoubleBufferU.put.

Doc from java.nio.DoubleBuffer.put.

Absolute put method  (optional operation).

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

sliceback to summary
public DoubleBuffer slice()

Overrides java.nio.DirectDoubleBufferU.slice.

Doc from java.nio.DoubleBuffer.slice.

Creates a new double 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 doubles remaining in this buffer, its mark will be undefined, and its byte order will be identical to that 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.

sliceback to summary
public DoubleBuffer slice(int index, int length)

Overrides java.nio.DirectDoubleBufferU.slice.

Doc from java.nio.DoubleBuffer.slice.

Creates a new double buffer whose content is a shared subsequence of this buffer's content.

The content of the new buffer will start at position index in this buffer, and will contain length elements. 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 length, its mark will be undefined, and its byte order will be identical to that 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.
