Method Detail

edges

E[] edges()

Returns an array of all the edges to and from this CFGraphable.

pred

E[] pred()

Returns an array of all the edges entering this CFGraphable.

succ

E[] succ()

Returns an array of all the edges leaving this CFGraphable.

edgeC

List<E> edgeC()

Returns a List of all the edges to and from this HCodeElement.

predC

List<E> predC()

Returns a List of all the edges to this HCodeElement. Each CFGEdge returned is guaranteed to return this in response to a call to to(); the actual predecessor will be returned from from().

Specified by:

predC in interface Graph.Node<CFG extends CFGraphable<CFG,E>,E extends CFGEdge<CFG,E>>

succC

List<E> succC()

Returns a List of all the edges from this HCodeElement. Each CFGEdge returned is guaranteed to return this in response to a call to from(); the actual successor to this will be returned from to().

Specified by:

succC in interface Graph.Node<CFG extends CFGraphable<CFG,E>,E extends CFGEdge<CFG,E>>
