Member Function Documentation

c_modifier()

void wreport::bulletin::ScanFeatures::c_modifier ( Varcode  code, Opcodes &  next  )

overridevirtual

Notify of a C modifier.

Whenever the modifier is a supported one, this is followed by an invocation of one of the specific c_* methods.

Parameters

code	The C modifier code

Reimplemented from wreport::bulletin::Interpreter.

define_associated_field_significance()

unsigned wreport::bulletin::ScanFeatures::define_associated_field_significance ( Varinfo  info )

overridevirtual

Request processing of an associated field significance variable (B31021).

Returns

the associated field significance value

Reimplemented from wreport::bulletin::Interpreter.

define_bitmap()

void wreport::bulletin::ScanFeatures::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.

define_bitmap_delayed_replication_factor()

unsigned wreport::bulletin::ScanFeatures::define_bitmap_delayed_replication_factor ( Varinfo  info )

overridevirtual

Request processing of a delayed replication factor variable used to encode the size of a bitmap.

Returns

the repetition count

Reimplemented from wreport::bulletin::Interpreter.

r_replication()

void wreport::bulletin::ScanFeatures::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.
