Class StringProperty

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

public abstract class StringProperty extends ReadOnlyStringProperty implements Property<String>, WritableStringValue
This class provides a full implementation of a Property wrapping a String value. The value of a StringProperty can be get and set with ObservableObjectValue.get(), StringExpression.getValue(), WritableObjectValue.set(Object), and setValue(String). A property can be bound and unbound unidirectional with Property.bind(ObservableValue) and Property.unbind(). Bidirectional bindings can be created and removed with bindBidirectional(Property) and unbindBidirectional(Property). The context of a StringProperty can be read with ReadOnlyProperty.getBean() and ReadOnlyProperty.getName().

    • setValue

      public void setValue(String v)
      Set the wrapped value.
      Specified by:
      setValue in interface WritableValue<String>
      Parameters:
      v - The new value
    • bindBidirectional

      public void bindBidirectional(Property<String> other)
      Create a bidirectional binding between this Property and another one. Bidirectional bindings exists independently of unidirectional bindings. So it is possible to add unidirectional binding to a property with bidirectional binding and vice-versa. However, this practice is discouraged.

      It is possible to have multiple bidirectional bindings of one Property.

      JavaFX bidirectional binding implementation use weak listeners. This means bidirectional binding does not prevent properties from being garbage collected.

      Specified by:
      bindBidirectional in interface Property<String>
      Parameters:
      other - the other Property
    • bindBidirectional

      public <T> void bindBidirectional(Property<T> other, StringConverter<T> converter)
      Create a bidirectional binding between this StringProperty and another arbitrary property. Relies on an implementation of StringConverter for conversion.
      Type Parameters:
      T - the type of the wrapped Object
      Parameters:
      other - the other Property
      converter - the StringConverter used to convert between this StringProperty and the other Property
      Throws:
      NullPointerException - if other or converter is null
      IllegalArgumentException - if other is this

    • unbindBidirectional

      public void unbindBidirectional(Property<String> other)
      Remove a bidirectional binding between this Property and another one. If no bidirectional binding between the properties exists, calling this method has no effect. It is possible to unbind by a call on the second property. This code will work:
           property1.bindBirectional(property2);
           property2.unbindBidirectional(property1);
       
      Specified by:
      unbindBidirectional in interface Property<String>
      Parameters:
      other - the other Property
    • unbindBidirectional

      public void unbindBidirectional(Object other)
      Remove a bidirectional binding between this Property and another one. If no bidirectional binding between the properties exists, calling this method has no effect.
      Parameters:
      other - the other Property
      Throws:
      NullPointerException - if other is null
      IllegalArgumentException - if other is this

    • toString

      public String toString()
      Returns a string representation of this StringProperty object.
      Overrides:
      toString in class ReadOnlyStringProperty
      Returns:
      a string representation of this StringProperty object.
