  • getValue

    public String getValue()

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

    Specified by:

    getValue in interface ObservableValue<String>

    Returns:

    The current value

  • getValueSafe

    public final String getValueSafe()

    Returns usually the value of this StringExpression. Only if the value is null an empty String is returned instead.

    Returns:

    the value of this StringExpression or the empty String

  • stringExpression

    public static StringExpression stringExpression(ObservableValue<?> value)

    Returns a StringExpression that wraps a ObservableValue. If the ObservableValue is already a StringExpression, it will be returned. Otherwise a new StringBinding is created that holds the value of the ObservableValue converted to a String.

    Parameters:

    value - The source ObservableValue

    Returns:

    A StringExpression that wraps the ObservableValue if necessary

    Throws:

    NullPointerException - if value is null

  • concat

    public StringExpression concat(Object other)

    Returns a StringExpression that holds the value of this StringExpression concatenated with another Object.

    If the value of this StringExpression changes, the value of the resulting StringExpression is updated automatically. Also if the other Object is an implementation of ObservableValue, changes in the other Object are reflected automatically in the resulting StringExpression.

    Parameters:

    other - the other Object

    Returns:

    the new StringExpression

  • isEqualTo

    public BooleanBinding isEqualTo(ObservableStringValue other)

    the new BooleanBinding

  • isEqualTo

    public BooleanBinding isEqualTo(String other)

    Creates a new BooleanBinding that holds true if this StringExpression is equal to a constant value.
