# 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

- ## Method Details

  - ### 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`
      `format` - the `Format` used to convert between this `StringProperty` and the other `Property`
    Throws:
      `NullPointerException` - if `other` or `format` is `null`
      `IllegalArgumentException` - if `other` is `this`
    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.
    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`
    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`
      `IllegalArgumentException` - if `other` is `this`
    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.
