StringPropertyBase (JavaFX 17)

Module javafx.base
Package javafx.beans.property

## Class StringPropertyBase

- java.lang.Object
- - javafx.beans.binding.StringExpression
  - - javafx.beans.property.ReadOnlyStringProperty
    - - javafx.beans.property.StringProperty
      - - javafx.beans.property.StringPropertyBase

- All Implemented Interfaces:
    `Observable`, `Property<String>`, `ReadOnlyProperty<String>`, `ObservableObjectValue<String>`, `ObservableStringValue`, `ObservableValue<String>`, `WritableObjectValue<String>`, `WritableStringValue`, `WritableValue<String>`
  Direct Known Subclasses:
    `SimpleStringProperty`, `StyleableStringProperty`

      public abstract class StringPropertyBase
      extends StringProperty

  The class `StringPropertyBase` is the base class for a property wrapping a `String` value. It provides all the functionality required for a property except for the `ReadOnlyProperty.getBean()` and `ReadOnlyProperty.getName()` methods, which must be implemented by extending classes.
  Since:
    JavaFX 2.0
  See Also:
    `StringProperty`

- - ### Constructor Detail

    - #### StringPropertyBase

          public StringPropertyBase()

      The constructor of the `StringPropertyBase`.

    - #### StringPropertyBase

          public StringPropertyBase​(String initialValue)

      The constructor of the `StringPropertyBase`.
      Parameters:
        `initialValue` - the initial value of the wrapped `String`

  - ### Method Detail

    - #### fireValueChangedEvent

          protected void fireValueChangedEvent()

      Sends notifications to all attached `InvalidationListeners` and `ChangeListeners`. This method is called when the value is changed, either manually by calling `WritableObjectValue.set(java.lang.String)` or in case of a bound property, if the binding becomes invalid.

    - #### invalidated

          protected void invalidated()

      The method `invalidated()` can be overridden to receive invalidation notifications. This is the preferred option in `Objects` defining the property, because it requires less memory. The default implementation is empty.

    - #### toString

          public String toString()

      Returns a string representation of this `StringPropertyBase` object.
      Overrides:
        `toString` in class `StringProperty`
      Returns:
        a string representation of this `StringPropertyBase` object.
