Method Detail

call

public void call(byte[] buf_kv,
                 int ofs_kv,
                 byte[] buf_s,
                 int ofs_s)

Description copied from interface: UnboxedFunction

The function MUST support situations where the argument and return buffers overlap.

Specified by:

call in interface UnboxedFunction<Pair<K extends java.io.Serializable,java.lang.Double>,Pair<java.lang.Double,java.lang.Double>>

multiply

public void multiply(byte[] buf1,
                     int ofs1,
                     byte[] buf2,
                     int ofs2,
                     byte[] buf_dest,
                     int ofs_dest)

Description copied from interface: AssociativeOperation

Compute (buf1,ofs1)*(buf2,ofs2) and write it to (buf_dest,ofs_dest). MUST support the case where (buf1,ofs1)==(buf_dest,ofs_dest) or (buf2,ofs2)==(buf_dest,ofs_dest) or ther is some overlap. MUST BE ABLE TO DEAL WITH THE CASE WHERE DESTINATION BUFFER OVERLAPS ONE OF SOURCE BUFFERS!!!
