Method Detail

reset

protected void reset()

Description copied from class: AbstractInjectorGrapher

Resets the state of the grapher before rendering a new graph.

Specified by:

reset in class AbstractInjectorGrapher

setOut

public void setOut(PrintWriter out)

setRankdir

public void setRankdir(String rankdir)

postProcess

protected void postProcess()

Description copied from class: AbstractInjectorGrapher

Performs any post processing required after all nodes and edges have been added.

Specified by:

postProcess in class AbstractInjectorGrapher

getGraphAttributes

protected Map<String,String> getGraphAttributes()

start

protected void start()

finish

protected void finish()

renderNode

protected void renderNode(GraphvizNode node)

getNodeAttributes

protected Map<String,String> getNodeAttributes(GraphvizNode node)

getNodeLabel

protected String getNodeLabel(GraphvizNode node)

Creates the "label" for a node. This is a string of HTML that defines a table with a heading at the top and (in the case of ImplementationNodes) rows for each of the member fields.

renderEdge

protected void renderEdge(GraphvizEdge edge)

getEdgeAttributes

protected Map<String,String> getEdgeAttributes(GraphvizEdge edge)

getArrowString

protected String getArrowString(List<ArrowType> arrows)

Turns a List of ArrowTypes into a String that represents combining them. With Graphviz, that just means concatenating them.

getEdgeEndPoint

protected String getEdgeEndPoint(String nodeId,
                                 String portId,
                                 CompassPoint compassPoint)

htmlEscape

protected String htmlEscape(String str)

htmlEscape

protected List<String> htmlEscape(List<String> elements)

newInterfaceNode

protected void newInterfaceNode(InterfaceNode node)

Description copied from class: AbstractInjectorGrapher

Adds a new interface node to the graph.

Specified by:

newInterfaceNode in class AbstractInjectorGrapher

newImplementationNode

protected void newImplementationNode(ImplementationNode node)

Description copied from class: AbstractInjectorGrapher

Adds a new implementation node to the graph.

Specified by:

newImplementationNode in class AbstractInjectorGrapher

newInstanceNode

protected void newInstanceNode(InstanceNode node)

Description copied from class: AbstractInjectorGrapher

Adds a new instance node to the graph.

Specified by:

newInstanceNode in class AbstractInjectorGrapher

newDependencyEdge

protected void newDependencyEdge(DependencyEdge edge)

Description copied from class: AbstractInjectorGrapher

Adds a new dependency edge to the graph.

Specified by:

newDependencyEdge in class AbstractInjectorGrapher

newBindingEdge

protected void newBindingEdge(BindingEdge edge)

Description copied from class: AbstractInjectorGrapher

Adds a new binding edge to the graph.

Specified by:

newBindingEdge in class AbstractInjectorGrapher
