    public T getValue()

    Description copied from interface: ObservableValue
    Returns the current value of this ObservableValue

    Specified by:

    Returns:

    The current value

  • objectExpression

    public static <T> ObjectExpression<T> objectExpression(ObservableObjectValue<T> value)

    Returns an ObjectExpression that wraps an ObservableObjectValue. If the ObservableObjectValue is already an ObjectExpression, it will be returned. Otherwise a new ObjectBinding is created that is bound to the ObservableObjectValue.

    Parameters:

    value - The source ObservableObjectValue

    Returns:

    A ObjectExpression that wraps the ObservableObjectValue if necessary

    Throws:

    NullPointerException - if value is null

  • isEqualTo

    public BooleanBinding isEqualTo(ObservableObjectValue<?> other)

    Creates a new BooleanExpression that holds true if this and another ObservableObjectValue are equal.

    Parameters:

    other - the other ObservableObjectValue

    Returns:

    the new BooleanExpression

    Throws:

    NullPointerException - if other is null

  • isEqualTo

    public BooleanBinding isEqualTo(Object other)

    Creates a new BooleanExpression that holds true if this ObjectExpression is equal to a constant value.

    Parameters:

    other - the constant value

    Returns:

    the new BooleanExpression

  • isNotEqualTo

    public BooleanBinding isNotEqualTo(ObservableObjectValue<?> other)

    Creates a new BooleanExpression that holds true if this and another ObservableObjectValue are not equal.

    Parameters:

    other - the other ObservableObjectValue

    Returns:

    the new BooleanExpression

    Throws:

    NullPointerException - if other is null

  • isNotEqualTo

    public BooleanBinding isNotEqualTo(Object other)

    Creates a new BooleanExpression that holds true if this ObjectExpression is not equal to a constant value.

    Parameters:

    other - the constant value

    Returns:

    the new BooleanExpression

  • isNull

    public BooleanBinding isNull()

    Creates a new BooleanBinding that holds true if this ObjectExpression is null.

    Returns:

    the new BooleanBinding

  • isNotNull

    public BooleanBinding isNotNull()

    Creates a new BooleanBinding that holds true if this ObjectExpression is not null.

    Returns:

    the new BooleanBinding

  • asString

    public StringBinding asString()

    Creates a StringBinding that holds the value of this ObjectExpression turned into a String. If the value of this ObjectExpression changes, the value of the StringBinding will be updated automatically.

    Returns:

    the new StringBinding

    Since:

    JavaFX 8.0

  • asString

    public StringBinding asString(String format)

    Creates a StringBinding that holds the value of the ObjectExpression turned into a String. If the value of this ObjectExpression changes, the value of the StringBinding will be updated automatically.

    The result is formatted according to the formatting String. See java.util.Formatter for formatting rules.

    Parameters:

    format - the formatting String

    Returns:

    the new StringBinding

    Since:

    JavaFX 8.0

  • asString

    public StringBinding asString(Locale locale,
                                  String format)

    Creates a StringBinding that holds the value of the NumberExpression turned into a String. If the value of this NumberExpression changes, the value of the StringBinding will be updated automatically.

    The result is formatted according to the formatting String and the passed in Locale. See java.util.Formatter for formatting rules. See java.util.Locale for details on Locale.

    Parameters:

    format - the formatting String

    Returns:

    the new StringBinding

    Since:

    JavaFX 8.0
