Detailed Description

The interpose_stateful class is used to represent the processing to translate a stateful key stream into a stateless key stream.

Constructor & Destructor Documentation

interpose_stateful::~interpose_stateful

(

)

[virtual]

The destructor.

Definition at line 26 of file stateful.cc.

interpose_stateful::interpose_stateful	(	const interpose::pointer &	deeper,
		bool	jumper
	)		[private]

The constructor.

Parameters:

deeper	Where to send the stateless key stream.
jumper	whether or not to treat "UJ" statefully to become opcode_extended_goto.

Definition at line 31 of file stateful.cc.

interpose_stateful::interpose_stateful

(

)

[private]

The default constructor. Do not use.

interpose_stateful::interpose_stateful

(

const interpose_stateful &

)

[private]

The copy constructor. Do not use.

Member Function Documentation

interpose::pointer interpose_stateful::create	(	const interpose::pointer &	deeper,
		bool	jumper = false
	)		[static]

The create class method is used to create new dynamically allocated instances of this class.

Parameters:

deeper	Where to send the stateless key stream.
jumper	whether or not to treat "UJ" statefully to become opcode_extended_goto.

Definition at line 40 of file stateful.cc.

void interpose_stateful::on_error_v	(	const char *	fmt,
		va_list	ap
	)		[protected, virtual]

The on_error_v method is used to report errors processing the key stream.

Parameters:

fmt	The format of the error. This controls the numer and types of the following arguments.
ap	The following arguments.

Implements interpose.

Definition at line 341 of file stateful.cc.

void interpose_stateful::on_opcode	(	opcode_t	op,
		const location::pointer &	where
	)		[protected, virtual]

The on_opcode method is used to process keys that have a corresponding opcode.

Parameters:

op	The opcode (usually a key stroke) of interest
where	The source file location, or NULL if not available.

Implements interpose.

Definition at line 47 of file stateful.cc.

interpose_stateful& interpose_stateful::operator=

(

const interpose_stateful &

)

[private]

The assignment operator. Do not use.

bool interpose_stateful::strict_memory_number_checking_required

(

void

)

const [protected, virtual]

The strict_memory_number_checking_required method is used to determine whether or not the number keys following M3~ keys (et al) must be followed by a digit key (true) or any key (false). The actual 1614P silently permits any key, and uses only the lower 4 bits.

Implements interpose.

Member Data Documentation

pointer interpose_stateful::deeper [private]

The deeper instance variable is used to remember where to send the stateless key stream.

Definition at line 75 of file stateful.h.

pointer interpose_stateful::diversion [private]

The diversion instance variable is used to remember where to send the stateless key stream, when multiple keys need to be folded into one virtual key.

Definition at line 88 of file stateful.h.

bool interpose_stateful::jumper [private]

The jumper instance variuable is used to remember whether or not to treat "UJ" statefully to become opcode_extended_goto.

Definition at line 81 of file stateful.h.
