A set of user properties can be associated with graphic objects.
User properties are a set of key-value pairs, where the key is a
String
object and the value may be any kind of information value. These
user property methods of the class IlvGraphic let you easily connect information
that comes from your application to your graphic objects. You can
keep track of the graphic part of your application by storing the
references to objects you create and connecting this graphic part
to the application by means of user properties, as in the following
example:
Integer index = new Integer(10); String key = "objectIndex"; myobject.setProperty(key, index);
The following IlvGraphic methods help you manage the
properties of an object:
public boolean hasProperty(String key, Object value)
public boolean removeProperty(String key)
public Object getProperty(String key)
public boolean replaceProperty(String key, Object value)
public void setProperty(String key, Object value)
