Detailed Description

The interpose_memory class is used to represent the processing required to glue a key stroke to an xM3~ key, to build a complete xM(n) pseudo keystroke.

Constructor & Destructor Documentation

interpose_memory::~interpose_memory

(

)

[virtual]

The destructor.

Definition at line 21 of file memory.cc.

interpose_memory::interpose_memory	(	const pointer &	deeper,
		int	base,
		const location::pointer &	start
	)		[protected]

The constructor. For use by derived classes only.

Parameters:

deeper	Where to send the stateless key stream.
base	The base value of the range of opcodes corresponding to digits, counting from zero (even if zero isn't legal).
start	where the XM3~ token was

Definition at line 26 of file memory.cc.

interpose_memory::interpose_memory

(

)

[private]

The default constructor. Do not use.

interpose_memory::interpose_memory

(

const interpose_memory &

rhs

)

[private]

The copy constructor. Do not use.

Parameters:

rhs	The right hand side of the initialization.

Member Function Documentation

void interpose_memory::on_error_v	(	const char *	fmt,
		va_list	ap
	)		[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 350 of file memory.cc.

void interpose_memory::on_opcode	(	opcode_t	op,
		const location::pointer &	where
	)		[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 40 of file memory.cc.

interpose_memory& interpose_memory::operator=

(

const interpose_memory &

rhs

)

[private]

The assignment operator. Do not use.

Parameters:

rhs	The right hand side of the assignment.

bool interpose_memory::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.

Definition at line 357 of file memory.cc.

Member Data Documentation

int interpose_memory::base [private]

The base instance variable is used to remember the base value of the range of opcodes corresponding to digits, counting from zero (even if zero isn't legal).

Definition at line 74 of file memory.h.

pointer interpose_memory::deeper [private]

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

Definition at line 67 of file memory.h.

location::pointer interpose_memory::start [private]

The location of the first opcode, the one that is being extended.

Definition at line 79 of file memory.h.
