Node createConnectorNode(LayoutContext context, YList edgesIds, Object representedNodeId)
NodeInfo.TYPE_CONNECTOR
.
Note: all implementations have to use method LayoutContext.createNode(Object)
to create the node.
context
- an object providing relevant layout information, e.g., the current graph as well as
various information about the graph elements.edgesIds
- a list that contains the ids of edges that are split by this connector. Note: multi-edges
(edges connecting the same nodes) may be split by the same connector pair.representedNodeId
- the id of the node that is represented by this connector.
NodeInfo.TYPE_CONNECTOR
,
LayoutContext.createNode(Object)
,
NodeInfo.getRepresentedNode()
Node createProxyReferenceNode(LayoutContext context, Object referringProxyId)
NodeInfo.TYPE_PROXY_REFERENCE
.
Note: all implementations have to use method LayoutContext.createNode(Object)
to create the node.
context
- an object providing relevant layout information, e.g., the current graph as well as
various information about the graph elements.referringProxyId
- the id of the proxy to which the created node refers to.
NodeInfo.TYPE_PROXY_REFERENCE
,
LayoutContext.createNode(Object)
,
NodeInfo.TYPE_PROXY
Node createProxyNode(LayoutContext context, Object origNodeId)
NodeInfo.TYPE_PROXY
.
Note: all implementations have to use method LayoutContext.createNode(Object)
to create the node.
context
- an object providing relevant layout information, e.g., the current graph as well as
various information about the graph elements.origNodeId
- the id of the node for which a proxy has to be created.
LayoutContext.createNode(Object)
,
NodeInfo.TYPE_PROXY
Edge createConnectorEdge(LayoutContext context, Node connector, Node opposite, Object origEdgeId, boolean atTarget)
EdgeInfo.TYPE_CONNECTOR
.
The edge should connect the given connector and opposite node.
Note: all implementations have to use method LayoutContext.createEdge(y.base.Node, y.base.Node, Object)
to create the edge.
context
- an object providing relevant layout information, e.g., the current graph as well as
various information about the graph elements.connector
- the endpoint of the edge that represents the connector node.opposite
- the other endpoint of the edge.origEdgeId
- the id of the edge that is split by the connector edge.atTarget
- whether or not the connector node is the target of the edge.
EdgeInfo.TYPE_CONNECTOR
,
LayoutContext.createEdge(y.base.Node, y.base.Node, java.lang.Object)
Edge createProxyReferenceEdge(LayoutContext context, Node proxyReference, Node opposite, Object referencingCopyId)
EdgeInfo.TYPE_PROXY_REFERENCE
.
This (undirected) edge should connect the given proxy reference and opposite node.
Note: all implementations have to use method LayoutContext.createEdge(y.base.Node, y.base.Node, Object)
to create the edge.
context
- an object providing relevant layout information, e.g., the current graph as well as
various information about the graph elements.proxyReference
- the endpoint of the edge that represents the proxy
reference node.opposite
- the other endpoint of the new edge.referencingCopyId
- the id of the proxy node that is referenced by the
proxy reference node.
EdgeInfo.TYPE_PROXY_REFERENCE
,
NodeInfo.TYPE_PROXY_REFERENCE
,
LayoutContext.createEdge(y.base.Node, y.base.Node, java.lang.Object)
Edge createProxyEdge(LayoutContext context, Node proxyNode, Node opposite, Object replacingEdgeId, Object origNodeId)
EdgeInfo.TYPE_PROXY
.
The edge should connect the given proxy node and opposite node.
Note: all implementations have to use method LayoutContext.createEdge(y.base.Node, y.base.Node, Object)
to create the edge.
context
- an object providing relevant layout information, e.g., the current graph as well as
various information about the graph elements.proxyNode
- the endpoint of the edge that represents the proxy node.opposite
- the other endpoint of the new edge.replacingEdgeId
- the id of the related edge that is connected to the original node.origNodeId
- the id of the original node to which the proxy node refers to.
