Class AbstractLayoutAlgorithm

java.lang.Object
org.cytoscape.view.layout.AbstractLayoutAlgorithm
All Implemented Interfaces:
CyLayoutAlgorithm
public abstract class AbstractLayoutAlgorithm extends Object implements CyLayoutAlgorithm
The AbstractLayoutAlgorithm provides a basic implementation of a layout TaskFactory.

Cytoscape Backwards Compatibility (Abstract Class): This class is abstract and meant to be extended by users. This means that we may add methods for minor version updates. Methods will only be removed for major version updates.

  • Field Details

    • undoSupport

      protected final UndoSupport undoSupport
      An undo support object available for use

  • Constructor Details

    • AbstractLayoutAlgorithm

      public AbstractLayoutAlgorithm​(String computerName, String humanName, UndoSupport undoSupport)
      The Constructor.
      Parameters:
      computerName - a computer readable name used to construct property strings.
      humanName - a user visible name of the layout.

  • Method Details

    • createLayoutContext

      public Object createLayoutContext()
      Description copied from interface: CyLayoutAlgorithm
      Returns a new layout context object. This method can be used to create custom configurations for layouts.
      Specified by:
      createLayoutContext in interface CyLayoutAlgorithm
      Returns:
      a new layout context object.

    • getDefaultLayoutContext

      public final Object getDefaultLayoutContext()
      Description copied from interface: CyLayoutAlgorithm
      Returns the default instance of the layout context. This is the default layout configuration used in most cases.
      Specified by:
      getDefaultLayoutContext in interface CyLayoutAlgorithm
      Returns:
      the default instance of the layout context.

    • getName

      public String getName()
      Description copied from interface: CyLayoutAlgorithm
      Returns the computer-readable name of the layout. To get a human readable name, use toString().
      Specified by:
      getName in interface CyLayoutAlgorithm
      Returns:
      The computer-readable name of the layout.

    • toString

      public String toString()
      Description copied from interface: CyLayoutAlgorithm
      Returns the human-readable name of the layout.
      Specified by:
      toString in interface CyLayoutAlgorithm
      Overrides:
      toString in class Object
      Returns:
      The human-readable name of the layout.

    • getSupportedNodeAttributeTypes

      public Set<Class<?>> getSupportedNodeAttributeTypes()
      Description copied from interface: CyLayoutAlgorithm
      Returns the set of node attribute types potentially used by this layout algorithm. May (and frequently will) return an empty set.
      Specified by:
      getSupportedNodeAttributeTypes in interface CyLayoutAlgorithm
      Returns:
      types of allowable attribute types.

    • getSupportedEdgeAttributeTypes

      public Set<Class<?>> getSupportedEdgeAttributeTypes()
      Description copied from interface: CyLayoutAlgorithm
      Returns the set of node attribute types potentially used by this layout algorithm. May (and frequently will) return an empty set.
      Specified by:
      getSupportedEdgeAttributeTypes in interface CyLayoutAlgorithm
      Returns:
      types of allowable attribute types.

    • getSupportsSelectedOnly

      public boolean getSupportsSelectedOnly()
      Description copied from interface: CyLayoutAlgorithm
      Returns true if this algorithm supports being applied to only the currently selected nodes.
      Specified by:
      getSupportsSelectedOnly in interface CyLayoutAlgorithm
      Returns:
      true if this algorithm supports being applied to only the currently selected nodes.

    • isReady

      public boolean isReady​(CyNetworkView view, Object tunableContext, Set<View<CyNode>> nodesToLayout, String attributeName)
      Description copied from interface: CyLayoutAlgorithm
      Returns true if the task factory is ready to produce a task iterator.
      Specified by:
      isReady in interface CyLayoutAlgorithm
      Parameters:
      view - The network view that the layout algorithm should be applied to.
      tunableContext - The layout context for this layout algorithm.
      nodesToLayout - The set of node views to layout.
      attributeName - The possibly null name of the attribute to use for this layout.
      Returns:
      true if the task factory is ready to produce a task iterator.
