type of connections between object instances

define - create new linktype definition

  linktype define   AdminName {LinkType_DefineOption} [force];

clone - duplicate a linktype and set the properties for the new instance

  linktype clone  AdminName define AdminName {LinkType_EditOption} [force];

edit - update the linktype properties [data for removed fields will be lost]

  linktype edit   AdminName {LinkType_EditOption} [force];

show - print the linktype properties

  linktype show   AdminName [LinkType_GetOption] [Token_Option] [ExportFile_Option] ;

select - extract linktypes on the base of query filters

  linktype select AdminPatternList [moddate Date_Range] [LinkType_GetOption]
                                     [Token_Option] [ExportFile_Option] ;

undefine - remove a linktype from the database [all link instances will be deleted]

  linktype undefine AdminName ;

KEYWORDs
	application	the associated application menu
	clone	specifies the behaviour in case of from/to side object clonation: none link instances are kept at the reference objects move link instances are moved to the new objects duplicate link instances are replicated for the new objects
	duplicate	if false inhibits the creation of more than one link instance between the same two objects
	description	the linktype description
	event	event associated to a check or action trigger
	field	link field(s)
	force	this flag allows to ignore errors during the creation/update (for example, the trigger programs, the classes or fields not yet defined)
	form	default form used to edit the link field values in the user interface
	fromside / from.	cardinality the from-side link cardinality ( single = 1 / multiple = N ) class classes of objects allowed at the from side of the connection clone specifies the behaviour in case of clonation of from side objects note describes the from side connection meaning revision specifies the behaviour in case of revision of from side objects
	hidden	administration hidden objects are not visible/usable
	image	local path for the linktype icon to upload
	imagedata	base64 code for the linktype icon
	moddate	last modification date
	name	the linktype name
	program	trigger program associated to a specific event
	revision	specifies the behaviour in case of from/to side object revision: none link instances are kept at the reference objects move link instances are moved to the new objects duplicate link instances are replicated for the new objects
	toside / to.	cardinality the to-side link cardinality ( single = 1 / multiple = N ) class classes of objects allowed at the to side of the connection clone specifies the behaviour in case of clonation of to side objects note describes the to side connection meaning revision specifies the behaviour in case of revision of to side objects
	selflink	if false inhibits the creation of link instances of an object with itself
	svnrev	SVN repository revision number
	workflow	workflow associated to a specific event (starts automatically)
