		ncx_module_t *	mod,
		typ_def_t *	typdef,
		const xmlChar *	defval,
		obj_template_t *	obj
	)

Resolve a type-stmt.

Analyze the typdef within a single leaf or leaf-list statement Finish if a named type, and/or range clauses present, which were left unfinished due to possible forward references

  Algorithm for checking named types in 4 separate loops:
    1) resolve all open type name references
    2) check for any name loops in all named types
    3) check that all base types and builtin types
       in each type chain are correct.  Also check that
       all restrictions given are correct for that type
    4) Check all range clauses and resolve all min/max
       keyword uses to decimal numbers and validate that
       each range is well-formed.

Error messages are printed by this function!! Do not duplicate error messages upon error return

Parameters

pcb	parser control block
tkc	token chain from parsing (needed for error msgs)
mod	module in progress
typdef	typdef struct from leaf or leaf-list to check
defval	default value string for this leaf (may be NULL)
obj	obj_template containing this typdef NULL if this is a top-level union typedef, checking its nested unnamed type clauses

Returns: status of the operation

◆ yang_typ_resolve_type_final()

status_t yang_typ_resolve_type_final	(	tk_chain_t *	tkc,
		ncx_module_t *	mod,
		typ_def_t *	typdef,
		const xmlChar *	name,
		const xmlChar *	defval,
		obj_template_t *	obj
	)

Resolve a type-stmt (final pass)

Check default values for XPath types

Error messages are printed by this function!! Do not duplicate error messages upon error return

Parameters

tkc	token chain from parsing (needed for error msgs)
mod	module in progress
typdef	typdef struct from leaf or leaf-list to check

Resovlve the typeQ of typedefs.

Analyze the entire typeQ within the module struct Finish all the named types and range clauses, which were left unfinished due to possible forward references

Check all the types in the Q If a type has validation errors, it will be removed from the typeQ

  Algorithm for checking named types in 4 separate loops:

    2) check for any name loops in all named types
    3) check that all base types and builtin types
       in each type chain are correct.  Also check that
       all restrictions given are correct for that type
    4) Check all range clauses and resolve all min/max
       keyword uses to decimal numbers and validate that
       each range is well-formed.
