Class StringProperty

java.lang.Object
  • javafx.beans.binding.StringExpression
    • javafx.beans.property.ReadOnlyStringProperty
      • javafx.beans.property.StringProperty

All Implemented Interfaces:

Observable, Property<String>, ReadOnlyProperty<String>, ObservableObjectValue<String>, ObservableStringValue, ObservableValue<String>, WritableObjectValue<String>, WritableStringValue, WritableValue<String>

Direct Known Subclasses:

JavaBeanStringProperty, 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().

Since:

JavaFX 2.0

    • 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 void bindBidirectional(Property<?> other,
                                    Format format)
      Create a bidirectional binding between this StringProperty and another arbitrary property. Relies on an implementation of Format for conversion.

      Parameters:

      other - the other Property

      Throws:

      NullPointerException - if other or format is null

      Since:

      JavaFX 2.1

    • 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.

      Parameters:

      other - the other Property

      Throws:

      NullPointerException - if other or converter is null

      Since:

      JavaFX 2.1

    • 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

      Since:

      JavaFX 2.1

    • 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.
