Clipboard
Clipboard — Click element; copies data from one packet to another
Clipboard(RANGE_1, ..., RANGE_N)
Ports: 2 inputs, 2 outputs
Processing: agnostic
Takes as arguments one or more byte ranges to copy. When Clipboard receives a packet on input 0, it copies the selected bytes to the clipboard buffer and emits the packet unchanged on output 0. When receiving a packet on input 1, Clipboard updates the packet with the bytes from the buffer and outputs the modified packet on output 1. This way, data from a single packet can be copied to 0 or more packets.
Each RANGE is on the form x/n, where x is the offset and n the number
of bytes.
Each Clipboard input/output pair can work in either a push or a pull context.
Clipboard can also be used to copy data from one place in a packet to another, by looping the same packet back through Clipboard and using Strip and Unstrip to offset the packet data.
Passing a packet through input/output 1 before any packets have passed through input/output 0 will cause undefined data to be written into the packet. Passing a packet through input/output 1 which is too small for any one of the ranges will cause the packet contents to be undefined.
