Member Function Documentation

interpose::pointer interpose_ope::create

(

calculator *

subject

)

[static]

The create class method si sued to create new dynamically allocated istances of this class

Parameters:

subject

The calculator instance to drive.

Definition at line 34 of file ope.cc.

void interpose_ope::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 48 of file ope.cc.

void interpose_ope::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 41 of file ope.cc.

interpose_ope& interpose_ope::operator=

(

const interpose_ope &

)

[private]

The assignment operator. Do not use.

bool interpose_ope::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.
