com.sas.lang.DoubleData

All Implemented Interfaces:

com.sas.beans.PropertyChangeSource, com.sas.beans.VetoableChangeSource, ComponentInterface, com.sas.lang.DoubleDataInterface, com.sas.lang.StringDataInterface, LinkPropertiesInterface, ModelInterface, com.sas.PublicClonable, ViewInterface, MultipleValueEventSourceInterface, java.beans.PropertyChangeListener, java.io.ObjectInputValidation, java.io.Serializable, java.lang.Cloneable, java.util.EventListener

public class DoubleData
implements com.sas.PublicClonable, com.sas.lang.DoubleDataInterface, com.sas.lang.StringDataInterface

DoubleData is an implementation of DoubleDataInterface, for holding a double integer. The DoubleData container has a bound doubleData property, so the DoubleData object fires a PropertyChangeEvent when the object is changed with setDoubleData(Double).

Creating a DoubleData Component

DoubleData doubleData1 = new DoubleData(); doubleData1.initialize();

The DoubleData class also maintains a bound text property which is always equal to the String value of the doubleData property.

Usage

The DoubleData component stores double data:

 doubleData1.addPropertyChangeListener(listener);
 doubleData1.setDoubleData(l);
 ...
 l = doubleData1.getDoubleData();
