question: synchronized private void outputBufferedChunk ( ) { if ( smallChunks == null || chunkSize == 0 ) { return ; } if ( smallChunks . size ( ) == 1 ) { outputChunk ( smallChunks . get ( 0 ) ) ; chunkSize = 0 ; smallChunks = null ; return ; } final IBindingSet [ ] chunk = new IBindingSet [ chunkSize ] ; int destPos = 0 ; for ( IBindingSet [ ] e : smallChunks ) { System . arraycopy ( e , 0 , chunk , destPos , e . length ) ; destPos += e . length ; } outputChunk ( chunk ) ; chunkSize = 0 ; smallChunks = null ; }
target:  Output the internal buffer.
