This function generates the code for the given drag reversing the output into the specified stream.

Function pointer parameters are not well treated by doxygen. TODO fix it.

Parameters

[in]	os	Where to write the code (output stream).
[in]	bd	BinaryDrag<conact> for which generating the code.
[in]	with_gotos	Whether to add gotos or not during code generation.
[in]	before	Pointer to the function which defines the string that should be put in the code before a tree. When dealing with forests for example you will need pass to GenerateDragCode a "before" function like the following one (i identifies the tree): [mapping](int i, const std::string& prefix) -> std::string { return prefix + "tree_" + string(i) + ": if ((c+=1) >= w - 1) goto " + prefix + "break_0_" + string(mapping[0][i]) + ";\n"; } this function is valid for example for thinning algorithms, PRED, SAUF, CTB and all the algorithms that have a unitary horizontal shift. When dealing with algorithm which have an horizontal shift of 2 and for this reason will need multiple end line forests a function like the following one is required: [mapping](int i, const std::string& prefix) -> std::string { return prefix + "tree_" + string(i) + ": if ((c+=2) >= w - 2) { if (c > w - 2) { goto " + prefix + \ "break_0_" + string(mapping_[0][i]) + "; } else { goto " + prefix + \ "break_1_" + string(mapping_[1][i]) + "; } } \n"; } DefaultBefore function returns an empty string and is the default function passed to the GenerateDragCode function.
[in]	after	Pointer to the function which defines the string that should be put into the code after a tree. When dealing with forest for example you will need pass to GenerateDragCode a "before" function like the following one: [mapping](int i, const std::string& prefix) -> std::string { return string(2, '\t') + "continue;\n"; }
[in]	prefix	String to add before tree names. This variable will be passed to the before and after functions
[in]	start_id	Is the id from which start node enumeration when dealing with drags. It is especially useful to avoid multiple defined labels when dealing with multiple forests in the same code, like for example when having a special forest for the first line e for the last one.
[in]	mapping	Mapping between main and end-of-the line trees. Default value is an empty mapping.
[in]	end_group_id	It is the id of the end-line forest group. It is needed when an algorithm requires multiple end-line forest group, such as when dealing with block-based approaches. Default value is zero.

Returns: The last id used during code generation. This is useful when multiple must be written in the same file.

◆ GenerateLineForestCode()

size_t GenerateLineForestCode	(	std::ostream &	os,
		const LineForestHandler &	lfh,
		std::string	prefix,
		size_t	start_id,
		std::string	before_mainsize_t index, const std::string &prefix, const std::vector< std::vector< size_t >> &mapping, size_t end_group_id = `BeforeMainShiftOne`,
		std::string	after_mainsize_t index, const std::string &prefix, const std::vector< std::vector< size_t >> &mapping, size_t end_group_id = `DefaultEmptyFunc`,
		std::string	before_endsize_t index, const std::string &prefix, const std::vector< std::vector< size_t >> &mapping, size_t end_group_id = `BeforeEnd`,
