const Varcode *	end
	One-past-the-last element of the varcode sequence.

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

next()

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, and Opcodes().

pop_left() [1/2]

Varcode wreport::Opcodes::pop_left ( )

inline

Return the first element and advance begin to the next one.

If the sequence is empty, throw an exception

References begin, and empty().

pop_left() [2/2]

Opcodes wreport::Opcodes::pop_left ( unsigned  count )

inline

Return the first count elements and advance begin to the first opcode after the sequence.

If the sequence has less that count elements, throw an exception

References begin, size(), and wreport::error_consistency::throwf().
