  yext.graphml.writer.YGraphElementProvider
      yext.graphml.compat.DotnetGraphElementProvider

All Implemented Interfaces:

GraphElementProvider

public class DotnetGraphElementProvider

extends YGraphElementProvider

Implementation of GraphElementProvider that also writes port elements for .NET graphml. The port elements are generated from the edges' source resp. target points. This class is meant to be used together with WriteEdgeLayoutHandler, WriteNodeLayoutHandler, WritePortLayoutHandler

Constructor Detail

DotnetGraphElementProvider

public DotnetGraphElementProvider(Graph graph)

Creates a new instance for a given graph.

Parameters:

graph - the graph which stores the data for this instance.

Method Detail

isMergePorts

public boolean isMergePorts()

Returns whether ports at the same location should be merged to a single port.

Returns:

true iff ports at the same location should be merged to a single port.

See Also:

setMergePorts(boolean)

setMergePorts

public void setMergePorts(boolean mergePorts)

Sets whether ports at the same location should be merged to a single port. If false, each edge will connect to a unique port, even if the ports location is identical to other edge ports. Default is false.

Parameters:

mergePorts -
