asReadOnlyBuffer back to summary

asReadOnlyBuffer	back to summary
public DoubleBuffer asReadOnlyBuffer() Implements abstract java.nio.DoubleBuffer.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.

public DoubleBuffer asReadOnlyBuffer()

compact back to summary

compact	back to summary
public DoubleBuffer compact() Implements abstract java.nio.DoubleBuffer.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.
