Detailed Description

Constructor & Destructor Documentation

◆ DDSPrinter()

wreport::bulletin::DDSPrinter::DDSPrinter	(	const Bulletin &	b,
		FILE *	out,
		unsigned	subset_idx
	)

Create a new DDS printer.

Parameters

b	Reference to the bulletin being visited
out	FILE to print to

Member Function Documentation

◆ define_bitmap()

void wreport::bulletin::DDSPrinter::define_bitmap ( unsigned bitmap_size )

overridevirtual

Request processing of a data present bitmap.

Parameters

code	The C modifier code that defines the bitmap
rep_code	The R replicator that defines the bitmap
delayed_code	The B delayed replicator that defines the bitmap length (it is 0 if the length is encoded in the YYY part of rep_code
ops	The replicated opcodes that define the bitmap

Returns: The bitmap that has been processed.

Reimplemented from wreport::bulletin::Interpreter.

◆ encode_associated_field()

void wreport::bulletin::DDSPrinter::encode_associated_field ( const Var & var )

overridevirtual

Encode an attribute for an associated field.

Var is the variable that the associated field refers to. The actual value of the associated field can be looked up using the functions in this->associated_field.

Reimplemented from wreport::bulletin::UncompressedEncoder.

◆ encode_var()

void wreport::bulletin::DDSPrinter::encode_var	(	Varinfo	info,
		const Var &	var
	)

overridevirtual

Encode a variable.

By default, this raises error_unimplemented. For decoders that encode normal variables, delayed replication factors, bitmap delayed replication factors, and associated field significances in the same way, can just override this method and use the default define_* implementations.

Reimplemented from wreport::bulletin::UncompressedEncoder.

◆ r_replication()

void wreport::bulletin::DDSPrinter::r_replication	(	Varcode	code,
		Varcode	delayed_code,
		const Opcodes &	ops
	)

overridevirtual

Handle a replicated section.

Parameters

code	The R replication code
delayed_code	The delayed replication B code, or 0 if delayed replication is not used
ops	The replicated operators

Reimplemented from wreport::bulletin::Interpreter.

◆ run_d_expansion()

void wreport::bulletin::DDSPrinter::run_d_expansion ( Varcode code )

overridevirtual

Executes the expansion of code, which has been put on top of the opcode stack.

By default it just calls run(), but it can be overridden to execute operations before and after.

Parameters

code	The D code that is being run

Reimplemented from wreport::bulletin::Interpreter.
