    Gets a node preceding this node in the CFG.

    from ControlFlowNode
    getASuccessor

    Gets a node succeeding this node in the CFG.

    from ControlFlowNode
    getBasicBlock

    Gets the basic block this node belongs to.

    from ControlFlowNode
    getContainer

    Gets the function or toplevel to which this node belongs.

    from NodeInStmtContainer
    getEndLine

    Gets the line on which this element ends.

    from Locatable
    getFile

    Gets the file this program element comes from.

    from Locatable
    getLocation

    Gets this element’s location.

    from Locatable
    getNumLines

    Gets the number of lines covered by this element.

    from Locatable
    getStartLine

    Gets the line on which this element starts.

    from Locatable
    isAFinalNode

    Holds if this is a final node, that is, a CFG node where execution of a toplevel or function terminates.

    from ControlFlowNode
    isAFinalNodeOfContainer

    Holds if this is a final node of container, that is, a CFG node where execution of that toplevel or function terminates.

    from ControlFlowNode
    isBranch

    Holds if this is a node with more than one successor.

    from ControlFlowNode
    isJoin

    Holds if this is a node with more than one predecessor.

    from ControlFlowNode
    isStart

    Holds if this is a start node, that is, the CFG node where execution of a toplevel or function begins.

    from ControlFlowNode
    isUnreachable

    Holds if this node is unreachable, that is, it has no predecessors in the CFG. Entry nodes are always considered reachable.

    from ControlFlowNode
    toString

    Gets a textual representation of this element.
