Detailed Description

Sequence of opcodes, as a slice of a Varcode vector.

This is used for BUFR and CREX encoding and decoding.

It can be considered as a sort of subroutine to be interpreted by the encoders/decoders.

Member Function Documentation

Opcodes wreport::Opcodes::next ( ) const [inline]

List of all opcodes after the first one.

If the list is empty, return the empty list

References begin, end, Opcodes(), and vals.

Opcodes& wreport::Opcodes::operator= ( const Opcodes & o ) [inline]

Assignment only works if the Opcodes share the same vector.

References begin, and end.

Walk the structure of the opcodes sending events to an opcode::Visitor.

Initialise e.dtable with dtable.

void wreport::Opcodes::visit ( opcode::Visitor & e ) const

Walk the structure of the opcodes sending events to an opcode::Visitor.

Assume that e.dtable is already initialised.
