Constructor Detail

Loop

public Loop(NodeList<CFG,Statement,Edge> cfgMatrix,
            Statement condition,
            Statement firstFollower,
            java.util.Collection<Statement> body)

Builds the loop.

Parameters:

cfgMatrix - the matrix of the cfg containing this loop

condition - the condition of the loop

firstFollower - the first statement after the loop exits

body - the statements in the loop body
