Abstract
Downstream buffer objects are slaved with the immediate upstream buffer object using a conventional “write remaining” method. The write remaining method can be invoked from each of a plurality of modules having access to the read and write pipes, and operates to slave not the data, but wrappers that point to the data and which therefore represent references to a single copy of the data stored as an upstream data buffer object, so that the actual data need exist in only one place after the write remaining method has been invoked, rather than requiring the data to be sequentially copied from one data buffer to the next. This method further has the benefit of allowing control to be returned to the module during the data transfer function, and of allowing additional data to be written to the outbound pipe.
