getReductionBuf
Create a buffer for performing parallel reduction using the given binary operation. The results of the reduction are placed into this buffer.Operations performed on the returned reduction buffer have the same effect as operations performed on this buffer, except whenever a source item S is put into a destination item D in this buffer, D is set to D op S, that is, the reduction of D and S using the given binary operation (rather than just setting D to S). Create a buffer for performing parallel reduction using the given binary operation. The results of the reduction are placed into this buffer. Create a buffer for performing parallel reduction using the given binary operation. The results of the reduction are placed into this buffer.
- Overrides:
getReductionBuf
in classSharedObjectArrayBuf<T>
- Parameters:
op
- Binary operation.- Returns:
- a
Buf
object. - Throws:
ClassCastException
- (unchecked exception) Thrown if this buffer's element data type and the given binary operation's argument data type are not the same.
