DoubleBuffer

Creates a double buffer based on a newly allocated double array.

Returns the array that backs this buffer (optional operation). The returned value is the actual array, not a copy, so modifications to the array write through to the buffer.

Subclasses 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.)

Returns the offset into the array returned by array 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.)

Returns a read-only buffer that shares its content with this buffer.

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 that this buffer's change of content will be visible to the new buffer. The two buffer's position, limit and mark are independent.

Compacts this double buffer.

The remaining doubles will be moved to the head of the buffer, staring from position zero. Then the position is set to remaining() ; the limit is set to capacity; the mark is cleared.

Compare the remaining doubles of this buffer to another double buffer's remaining doubles.

Returns a duplicated buffer that shares its content with this buffer.

The duplicated buffer's position, limit, capacity and mark are the same as this buffer's. The duplicated buffer's read-only property and byte order are the same as this buffer's, too.

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.

Checks whether this double buffer is equal to another object. If other is not a DoubleBuffer then false is returned.

Two double buffers are equal if their remaining doubles are equal. Position, limit, capacity and mark are not considered.

This method considers two doubles a and b to be equal if a == b or if a and b are both NaN . Unlike equals(Object) , this method considers -0.0 and +0.0 to be equal.

Returns a double at the specified index; the position is not changed.

Reads doubles from the current position into the specified double array, starting from the specified offset, and increases the position by the number of doubles read.

Reads doubles from the current position into the specified double array and increases the position by the number of doubles read.

Calling this method has the same effect as get(dst, 0, dst.length) .

Returns the double at the current position and increases the position by 1.

Returns true if array 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 .

Calculates this buffer's hash code from the remaining chars. The position, limit, capacity and mark don't affect the hash code.

Indicates whether this buffer is direct. A direct buffer will try its best to take advantage of native memory APIs and it may not stay in the Java heap, so it is not affected by garbage collection.

A double buffer is direct if it is based on a byte buffer and the byte buffer is direct.

Returns the byte order used by this buffer when converting doubles from/to bytes.

If this buffer is not based on a byte buffer, then this always returns the platform's native byte order.

Writes doubles from the given double array, starting from the specified offset, to the current position and increases the position by the number of doubles written.

Writes all the remaining doubles of the src double buffer to this buffer's current position, and increases both buffers' position by the number of doubles copied.

Write a double to the specified index of this buffer and the position is not changed.

Writes doubles from the given double array to the current position and increases the position by the number of doubles written.

Calling this method has the same effect as put(src, 0, src.length) .

Writes the given double to the current position and increases the position by 1.

Returns a sliced buffer that shares its content with this buffer.

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 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.

Creates a new double buffer by wrapping the given double array.

The new buffer's position will be start , limit will be start + doubleCount , capacity will be the length of the array.

Creates a new double buffer by wrapping the given double array.

Calling this method has the same effect as wrap(array, 0, array.length) .
