Constructor Detail

SchemaDiagram

public SchemaDiagram(ISchemaDataSet model)

Schema diagram constructor.

Parameters:

model - The schema presentation data set

Method Detail

initDiagramLayout

public void initDiagramLayout(org.eclipse.core.runtime.IProgressMonitor monitor)

If diagram has not been initialized before (is just created), the method performs default layout for all IVisualSchemaNode elements. Otherwise it keeps original positions.

Specified by:

initDiagramLayout in interface ISchemaDiagram

Parameters:

monitor - progress monitor used to set progress bar

layoutSelectedNode

public void layoutSelectedNode(Collection<ISchemaNode> visualNodes,
                               ILayoutAlgorithm layout,
                               org.eclipse.core.runtime.IProgressMonitor monitor)

Performs the specified layout on the given visual nodes.

Specified by:

layoutSelectedNode in interface ISchemaDiagram

Parameters:

visualNodes - nodes on which the layout will be performed

layout - layout to perform

monitor - progress monitor

ISchemaDiagram.layoutSelectedNode(java.util.Collection, pl.edu.agh.cast.schema.editor.layout.algorithm.ILayoutAlgorithm, org.eclipse.core.runtime.IProgressMonitor)

getDefaultLayout

public static ILayoutAlgorithm getDefaultLayout()

Returns a default layout algorithm for schema diagram.

Returns:

layout algorithm
