Class MutableBoolean

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<MutableBoolean>, Mutable<java.lang.Boolean>
    public class MutableBoolean
extends java.lang.Object
implements Mutable<java.lang.Boolean>, java.io.Serializable, java.lang.Comparable<MutableBoolean>
    A mutable boolean wrapper.

    Note that as MutableBoolean does not extend Boolean, it is not treated by String.format as a Boolean parameter.
