User Defined Attributes : UDAs in User Elements

UDAs in User Elements

UDAs are applicable to all database types.

Having defined and compiled a set of UDAs in LEXICON, those elements defined as using UDAs will have the UDA UDNAME, preceded by a colon and followed by the UDA’s default setting, added to their standard attribute lists. For example, suppose an INTEGER UDA has been defined as follows:


	Name /INT
	Lock false
	Owner /UGRO1
	Udname ’CAPACITY’
	Ablen 3
	Utype INT
	Ulen 1
	Rptx text
	Dflt 80
	Descript text
	Elelist SITE
	Reflist

Querying the attributes of a SITE element in MODEL would give something like:


	Name /SITE1
	Lock false
	Owner /*
	Position E 0mm N 0mm U 0mm
	Orient
		Y is N
	and	Z is U
	:CAP 80

The UDA instance, that is, the reference to the UDA definition, appears at the end of the attribute list, with a colon as its first character.
