        The constructor of ReadOnlyListProperty.
    • Method Detail

      • bindContentBidirectional

        public void bindContentBidirectional​(ObservableList<E> list)
        Creates a bidirectional content binding of the ObservableList, that is wrapped in this ReadOnlyListProperty, and another ObservableList.

        A bidirectional content binding ensures that the content of two ObservableLists is the same. If the content of one of the lists changes, the other one will be updated automatically.

        Parameters:
        list - the ObservableList this property should be bound to
        Throws:
        NullPointerException - if list is null
        IllegalArgumentException - if list is the same list that this ReadOnlyListProperty points to
      • unbindContentBidirectional

        public void unbindContentBidirectional​(Object object)
        Deletes a bidirectional content binding between the ObservableList, that is wrapped in this ReadOnlyListProperty, and another Object.
        Parameters:
        object - the Object to which the bidirectional binding should be removed
        Throws:
        NullPointerException - if object is null
        IllegalArgumentException - if object is the same list that this ReadOnlyListProperty points to
      • bindContent

        public void bindContent​(ObservableList<E> list)
        Creates a content binding between the ObservableList, that is wrapped in this ReadOnlyListProperty, and another ObservableList.

        A content binding ensures that the content of the wrapped ObservableLists is the same as that of the other list. If the content of the other list changes, the wrapped list will be updated automatically. Once the wrapped list is bound to another list, you must not change it directly.

        Parameters:
        list - the ObservableList this property should be bound to
        Throws:
        NullPointerException - if list is null
        IllegalArgumentException - if list is the same list that this ReadOnlyListProperty points to
      • unbindContent

        public void unbindContent​(Object object)
        Deletes a content binding between the ObservableList, that is wrapped in this ReadOnlyListProperty, and another Object.
        Parameters:
        object - the Object to which the binding should be removed
        Throws:
        NullPointerException - if object is null
        IllegalArgumentException - if object is the same list that this ReadOnlyListProperty points to
      • equals

        public boolean equals​(Object obj)
        Description copied from class: Object
        Indicates whether some other object is "equal to" this one.

        The equals method implements an equivalence relation on non-null object references:

        • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
        • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
        • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
        • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
        • For any non-null reference value x, x.equals(null) should return false.

        The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).

        Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

        Specified by:
        equals in interface Collection<E>
        Specified by:
        equals in interface List<E>
        Overrides:
        equals in class Object
        Parameters:
        obj - the reference object with which to compare.
        Returns:
        true if this object is the same as the obj argument; false otherwise.

      • hashCode

        public int hashCode​()
        Description copied from class: Object
        Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

        The general contract of hashCode is:

        • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
        • If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
        • It is not required that if two objects are unequal according to the Object.equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

        As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (The hashCode may or may not be implemented as some function of an object's memory address at some point in time.)

        Specified by:
        hashCode in interface Collection<E>
        Specified by:
        hashCode in interface List<E>
        Overrides:
        hashCode in class Object
        Returns:
        a hash code value for this object.

      • toString

        public String toString​()
        Returns a string representation of this ReadOnlyListProperty object.
        Overrides:
        toString in class Object
        Returns:
        a string representation of this ReadOnlyListProperty object.
