instance:EmptyPortsCandidateProvider [read-only] A static instance of this class.
public static function get instance():EmptyPortsCandidateProvider| getCandidateSourcePortCandidates | () | method |
public function getCandidateSourcePortCandidates(context:IInputModeContext, target:IPortCandidate):IterableReturns the source port candidates for the current node which apply for the provided (opposite) target port candidate.
The iterable may contain valid, invalid and dynamic port candidates.
This method is currently not queried by library classes.
Parameters
context:IInputModeContext — The context for which the candidates should be provided.
| |
target:IPortCandidate — The opposite port candidate.
|
Iterable — An Iterable over all port candidates that are associated with the given opposite port.
|
| getCandidateTargetPortCandidates | () | method |
public function getCandidateTargetPortCandidates(context:IInputModeContext, source:IPortCandidate):IterableReturns the target port candidates for the current node which apply for the provided (opposite) source port candidate.
The iterable may contain valid, invalid and dynamic port candidates.
This method is used during edge creation to collect possible target locations.
Parameters
context:IInputModeContext — The context for which the candidates should be provided.
| |
source:IPortCandidate — The opposite port candidate.
|
Iterable — An Iterable over all port candidates that are associated with the given opposite port.
|
| getEdgeSourcePortCandidates | () | method |
public function getEdgeSourcePortCandidates(context:IInputModeContext, edge:IEdge):IterableReturns all port candidates the provided edge's source side can connect to.
The iterable may contain valid, invalid and dynamic port candidates.
This method is used during relocation of the source side of an existing edge to collect possible locations at
the current source node.
Note that if using the AllCandidatesEdgePortCandidateProvider for edge relocation,
getGraphSourcePortCandidates is used instead of this method to return possible source locations.
Parameters
context:IInputModeContext — The context for which the candidates should be provided.
| |
edge:IEdge — The edge for which source port candidates are sought.
|
Iterable — An Iterable over all port candidates that are associated with the given edge.
|
| getEdgeTargetPortCandidates | () | method |
public function getEdgeTargetPortCandidates(context:IInputModeContext, edge:IEdge):IterableReturns all port candidates the provided edge's target side can connect to.
The iterable may contain valid, invalid and dynamic port candidates.
This method is used during relocation of the target side of an existing edge to collect possible locations at
the current target node.
Note that if using the AllCandidatesEdgePortCandidateProvider for edge relocation,
getGraphTargetPortCandidates is used instead of this method to return possible target
locations.
Parameters
context:IInputModeContext — The context for which the candidates should be provided.
| |
edge:IEdge — The edge for which target port candidates are sought.
|
Iterable — An Iterable over all port candidates that are associated with the given edge.
|
| getGraphSourcePortCandidates | () | method |
public function getGraphSourcePortCandidates(context:IInputModeContext):IterableReturns all source port candidates that belong to the context of this provider.
The iterable may contain valid, invalid and dynamic port candidates.
This method is used during edge creation to collect possible start points.
In addition if using the AllCandidatesEdgePortCandidateProvider for edge relocation,
this method is used instead of getEdgeSourcePortCandidates to return possible source and target
locations.
Parameters
context:IInputModeContext — The context for which the candidates should be provided.
|
Iterable — An iterable over all source port candidates that are associated with the current context.
|
| getGraphTargetPortCandidates | () | method |
public function getGraphTargetPortCandidates(context:IInputModeContext):IterableReturns all target port candidates that belong to the context of this provider.
The iterable may contain valid, invalid and dynamic port candidates.
This method is not used per default.
Note however that if using the AllCandidatesEdgePortCandidateProvider for edge relocation,
this method is used instead of getEdgeTargetPortCandidates to return possible target locations.
Parameters
context:IInputModeContext — The context for which the candidates should be provided.
|
Iterable — An iterable over all target port candidates that are associated with the current context.
