Class ControlFlowLogic


  • public class ControlFlowLogic
    extends Object
    Consider Control Flow to determine which statements are reachable. Except for the special treatment of while, do, and for statements whose condition expression has the constant value true, the values of expressions are not taken into account in the flow analysis. See JLS 14.21

      • breakTarget

        public com.github.javaparser.ast.stmt.Statement breakTarget​(com.github.javaparser.ast.stmt.BreakStmt breakStmt)
        A break statement with no label attempts to transfer control to the innermost enclosing switch, while, do, or for statement of the immediately enclosing method or initializer; this statement, which is called the break target, then immediately completes normally. A break statement with label Identifier attempts to transfer control to the enclosing labeled statement (ยง14.7) that has the same Identifier as its label; this statement, which is called the break target, then immediately completes normally. In this case, the break target need not be a switch, while, do, or for statement.
      • exitTheStatement

        public boolean exitTheStatement​(com.github.javaparser.ast.stmt.BreakStmt breakStmt)
        A reachable break statement exits a statement if, within the break target, either there are no try statements whose try blocks contain the break statement, or there are try statements whose try blocks contain the break statement and all finally clauses of those try statements can complete normally.
      • continueADoStatement
