SexpProcessor

CompositeSexpProcessor

Implements the Composite pattern on SexpProcessor. Need we say more?

Yeah… probably. Implements a SexpProcessor of SexpProcessors so you can easily chain multiple to each other. At some stage we plan on having all of them run process and but only ever output something when generate is called, allowing for deferred final processing.

Attributes
