Method Detail

setSourceObject

public void setSourceObject(java.lang.Object obj)

Description copied from interface: IBoundObject

Set the source object that will be used as a reference for the bound object.

Specified by:

setSourceObject in interface IBoundObject

Overrides:

setSourceObject in class ObjectReference

Parameters:

obj - the source object

getValue

public java.lang.Object getValue(java.lang.String property)

Get the value of the given property from the source object.
If the source object is another IDataObject, the getValue call will be delegated to the source object.

Specified by:

getValue in interface IDataObject

Parameters:

property - the property to retrieve

Returns:

the value of the property, or null if there's a problem retrieving the value.

getHelper

protected PropertyHelper getHelper(java.lang.String property)

Get the property helper for the given property. The property helper is cached. If a helper for the given property isn't available, one is created.

Parameters:

property - the target property

Returns:

the PropertyHelper for this property

setValue

public void setValue(java.lang.String property,
                     java.lang.Object value)

Set the value of the given property on the source object to the given value.
If the source object is another IDataObject, the setValue call will be delegated to the source object.

Specified by:

setValue in interface IDataObject

Parameters:

property - the property to set

value - the value of the target property

toString

public java.lang.String toString()

Overrides:

toString in class ObjectReference

firePropertyChanged

protected void firePropertyChanged(java.beans.PropertyChangeEvent event)

Specified by:

refresh in interface IBoundObject

Overrides:

Parameters:

property - the property to check

Returns:

true, if the property does not have a setter method, false otherwise

Throws:

java.lang.IllegalArgumentException - if the target property is invalid

isPrimitive

public boolean isPrimitive(java.lang.String property)
                    throws java.lang.IllegalArgumentException

Description copied from interface: IDataObject

Get to see if the type of the given property is a Java primitive type.
