Example 1 with ThrowingInstruction

use of org.jetbrains.plugins.groovy.lang.psi.controlFlow.impl.ThrowingInstruction in project intellij-community by JetBrains.

the class ControlFlowUtils method visitAllExitPointsInner.

private static boolean visitAllExitPointsInner(Instruction last, Instruction first, boolean[] visited, ExitPointVisitor visitor) {
    if (first == last)
