static <TextendsIGraphNode<T> HashMap<T, ArrayList<T> > com.google.security.zynamics.binnavi.API.helpers.GraphAlgorithms.getBackEdges	(	final IDirectedGraph< T,?>	graph,
		final T	rootNode
	)			throws MalformedGraphException [static]

Calculates the back edges of the current graph.

Parameters:

	graph	The input graph.
	rootNode	The root node of the graph.

Returns:

A HashMap which contains the relation of nodes and their respective back edges.

Exceptions:

MalformedGraphException

Thrown if the graph has more then one entry node.

static <TextendsIGraphNode<T> Tree<T> com.google.security.zynamics.binnavi.API.helpers.GraphAlgorithms.getDominatorTree	(	final IDirectedGraph< T,?>	graph,
		final T	rootNode,
		final HashMap< T, ITreeNode< T >>	mapping
	)			throws MalformedGraphException [static]

Parameters:

	graph	The input graph.
	rootNode	The root node of the graph.
	mapping	Output parameter which will contain the mapping between API object and internal TreeType.

Returns:

The generated dominator tree.

Exceptions:

MalformedGraphException

static <TextendsIGraphNode<T> ArrayList<Set<T> > com.google.security.zynamics.binnavi.API.helpers.GraphAlgorithms.getGraphLoops

(

final IDirectedGraph< T,?>

graph

)

throws MalformedGraphException [static]

Calculates the loops contained in a graph.

Parameters:

graph

the input graph

Returns:

A List of Sets where each set contains the nodes of one loop.

Exceptions:

MalformedGraphException

Thrown if the graph has more than one entry node.

static <NodeTypeextendsIGraphNode<NodeType> Set<NodeType> com.google.security.zynamics.binnavi.API.helpers.GraphAlgorithms.getLoopNodes	(	final NodeType	srcNode,
		final NodeType	dstNode
	)			[static]

Gets the nodes of a loop

Parameters:

	srcNode	The source node of the loop where the back edge originates from.
	dstNode	The destination node of the loop where the back edge points to.

Returns:

The Set of nodes which belong to the loop.

static <NodeTypeextendsIGraphNode<NodeType> Set<NodeType> com.google.security.zynamics.binnavi.API.helpers.GraphAlgorithms.getPredecessors

(

final NodeType

node

)

[static]

Returns all predecessors of a graph node.

Parameters:

node

The node which is the starting point of the predecessor search.

Returns:

The predecessors of the node in the graph.

static <NodeTypeextendsIGraphNode<NodeType> Set<NodeType> com.google.security.zynamics.binnavi.API.helpers.GraphAlgorithms.getSuccessors

(

final NodeType

node

)

[static]

Returns all successors of a graph node.

Parameters:

node

The node which is the starting point of the successor search.

Returns:

The successors of the node in the graph.
