Constructor Detail

mxFastOrganicLayout

public mxFastOrganicLayout(mxGraph graph)

Constructs a new fast organic layout for the specified graph.

Method Detail

isVertexIgnored

public boolean isVertexIgnored(java.lang.Object vertex)

Returns a boolean indicating if the given should be ignored as a vertex. This returns true if the cell has no connections.

Overrides:

isVertexIgnored in class mxGraphLayout

Parameters:

vertex - Object that represents the vertex to be tested.

Returns:

Returns true if the vertex should be ignored.

isUseInputOrigin

setUseInputOrigin

public void setUseInputOrigin(boolean value)

Parameters:

value -

isResetEdges

public boolean isResetEdges()

setResetEdges

public void setResetEdges(boolean value)

Parameters:

value -

isDisableEdgeStyle

public boolean isDisableEdgeStyle()

setDisableEdgeStyle

public void setDisableEdgeStyle(boolean value)

Parameters:

Parameters:

value -

getMaxDistanceLimit

public double getMaxDistanceLimit()

Returns:

moveCell

public void moveCell(java.lang.Object cell,
                     double x,
                     double y)

Description copied from interface: mxIGraphLayout

Notified when a cell is being moved in a parent that has automatic layout to update the cell state (eg. index) so that the outcome of the layout will position the vertex as close to the point (x, y) as possible.

Specified by:

moveCell in interface mxIGraphLayout

Overrides:

moveCell in class mxGraphLayout

Parameters:

cell - Cell which is being moved.

x - X-coordinate of the new cell location.

y - Y-coordinate of the new cell location.

execute

public void execute(java.lang.Object parent)

Description copied from interface: mxIGraphLayout

Executes the layout for the children of the specified parent.

Specified by:

execute in interface mxIGraphLayout

Overrides:

execute in class mxGraphLayout

Parameters:

parent - Parent cell that contains the children to be layed out.
