Northwoods.GoXam.Model Namespace > GraphLinksModel<NodeType,NodeKey,PortKey,LinkType> Class : IsLinkValid Method

fromdata
a node key identifying the node data from which the link comes
fromparam
an optional value identifying which port on the "from" node the link is connected to
todata
a node key identify the node data to which the link goes
toparam
an optional value identifying which port on the "to" node the link is connected to
This predicate is true if adding a link between two nodes/ports would result in a valid graph.

Syntax

Visual Basic (Declaration) 
Public Function IsLinkValid( _
   ByVal fromdata As NodeType, _
   ByVal fromparam As PortKey, _
   ByVal todata As NodeType, _
   ByVal toparam As PortKey _
) As Boolean
C# 
public bool IsLinkValid( 
   NodeType fromdata,
   PortKey fromparam,
   NodeType todata,
   PortKey toparam
)

Parameters

fromdata
a node key identifying the node data from which the link comes
fromparam
an optional value identifying which port on the "from" node the link is connected to
todata
a node key identify the node data to which the link goes
toparam
an optional value identifying which port on the "to" node the link is connected to

Remarks

This just calls CheckLinkValid to do the actual graph structure check.
