Most of these settings can also be configured from the command-line. They control features of the unparser directly without the programmer having to invervene by creating a subclss or chaining a new parser. Most of the switches simply turn things on and off.

Copying an unparser also copies its settings.

overrideprotectedvirtual

Mid-level unparser function.

This function emits some entity to the specified output stream. All call-specific state is supplied in the State reference so that this function can be called with a const parser references and is thread safe per state object. The high-level functions create the state – states are not intended for end users – before calling this mid-level function.

This mid-level function uses a combination of C++ virtual function calls and object chaining. The virtual functions allow subclasses to override or augment behavior from the base class, so that, e.g., an x86 operand expression can be output in a different format than an m68k expression. The object chaining allows one unparser to override or augment the behavior of another function and is used, for example, to provide HTML wrapping around various entities.

The object chaining is implemented in two parts: every unparser object has a nextUnparser pointer and the final unparser in the list has a null pointer for this property; the Unparser::State object has a frontUnparser method that returns the first unparser in this list. This mid-level function is expected to always invoke functions on the front unparser in order to give every parser in the chain a chance to influence behavior. The base implementation of this mid-level function defers to the next parser in the chain if there is one, otherwise it performs some default output that's hopefully appropriate for most unparsers.

All such chained and virtual emitters begin with the letters "emit".
