| Creates a FloatArrayBuffer object that wraps the given array. | |||||||||

| Create a FloatArrayBuffer that mirrors this one, meaning it shares a reference to this buffers ByteArrayAdapter and when changes are made to that data it is reflected in both. | |||||||||
| virtual | ~FloatArrayBuffer () | ||||||||
| virtual float * | array () | ||||||||
Returns the float array that backs this buffer (optional operation).Modifications to this buffer's content will cause the returned array's content to be modified, and vice versa.Invoke the hasArray method before invoking this method in order to ensure that this buffer has an accessible backing array.
| |||||||||
| virtual int | arrayOffset () | ||||||||
Returns the offset within this buffer's backing array of the first element of the buffer (optional operation).Invoke the hasArray method before invoking this method in order to ensure that this buffer has an accessible backing array.
| |||||||||
| virtual FloatBuffer * | asReadOnlyBuffer () const | ||||||||
Creates a new, read-only float 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.If this buffer is itself read-only then this method behaves in exactly the same way as the duplicate method.The new buffer's capacity, limit, position, and mark values will be identical to those of this buffer.
| |||||||||
| virtual FloatBuffer & | compact () | ||||||||
Compacts this buffer.The bytes between the buffer's current position and its limit, if any, are copied to the beginning of the buffer. That is, the byte at index p = position() is copied to index zero, the byte at index p + 1 is copied to index one, and so forth until the byte 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 bytes copied, rather than to zero, so that an invocation of this method can be followed immediately by an invocation of another relative put method.
| |||||||||
| virtual FloatBuffer * | duplicate () | ||||||||
Creates a new float 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 read-only if, and only if, this buffer is read-only.

Absolute get method.Reads the value at the given index.
| |||||||||
| virtual bool | hasArray () const | ||||||||
Tells whether or not this buffer is backed by an accessible float array.If this method returns true then the array and arrayOffset methods may safely be invoked. Subclasses should override this method if they do not have a backing array as this class always returns true.
| |||||||||
| virtual bool | isReadOnly () const | ||||||||
Tells whether or not this buffer is read-only.
| |||||||||

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

Writes the given floats into this buffer at the given index.
| |||||||||
| virtual FloatBuffer * | slice () const | ||||||||
Creates a new FloatBuffer 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 bytes remaining in this buffer, and its mark will be undefined. The new buffer will be read-only if, and only if, this buffer is read-only.
