type.
Parameters:
value - Initial value of the Property
Parameters:
type - The type of the value. | | public | ObjectProperty(Object value, Class type, boolean readOnly)
Creates a new instance of ObjectProperty with the given value, type
and read-only mode status.
Parameters:
value - Initial value of the property.
Parameters:
type - The type of the value. |
| ObjectProperty | | public ObjectProperty(Object value)(Code) | | Creates a new instance of ObjectProperty with the given value.
The type of the property is automatically initialized to be
the type of the given value.
Parameters:
value - Initial value of the Property |
| ObjectProperty | | public ObjectProperty(Object value, Class type)(Code) | | Creates a new instance of ObjectProperty with the given value and
type.
Parameters:
value - Initial value of the Property
Parameters:
type - The type of the value. The value must be assignable togiven type |
| ObjectProperty | | public ObjectProperty(Object value, Class type, boolean readOnly)(Code) | | Creates a new instance of ObjectProperty with the given value, type
and read-only mode status.
Parameters:
value - Initial value of the property.
Parameters:
type - The type of the value. value must beassignable to this type.
Parameters:
readOnly - Sets the read-only mode. |
| addListener | | public void addListener(Property.ValueChangeListener listener)(Code) | | Registers a new value change listener for this ObjectProperty.
Parameters:
listener - the new Listener to be registered |
| getType | | final public Class getType()(Code) | | Returns the type of the ObjectProperty. The methods
getValue and setValue must be compatible
with this type: one must be able to safely cast the value returned
from getValue to the given type and pass any variable
assignable to this type as an argument to setValue.
type of the Property |
| getValue | | public Object getValue()(Code) | | Gets the value stored in the Property.
the value stored in the Property |
| isReadOnly | | public boolean isReadOnly()(Code) | | Tests if the Property is in read-only mode. In read-only mode calls
to the method setValue will throw
ReadOnlyExceptions and will not modify the value of the
Property.
true if the Property is in read-only mode,false if it's not |
| removeListener | | public void removeListener(Property.ValueChangeListener listener)(Code) | | Remove a previously registered value change listener.
Parameters:
listener - listener to be removed |
| setReadOnly | | public void setReadOnly(boolean newStatus)(Code) | | Sets the Property's read-only mode to the specified status.
Parameters:
newStatus - new read-only status of the Property |
| setValue | | public void setValue(Object newValue) throws Property.ReadOnlyException, Property.ConversionException(Code) | | Set the value of the property. This method supports setting from
Strings if either String is directly
assignable to property type, or the type class contains a string
constructor.
Parameters:
newValue - New value of the property. Property.ReadOnlyException if the object is inread-only mode Property.ConversionException ifnewValue can't be converted into the Property's nativetype directly or through String |
| toString | | public String toString()(Code) | | Returns the value of the ObjectProperty in human readable textual
