Indexed Properties
An indexed property consists of multiple values. It can be identified by the following design
patterns, where N is the name of the property and T is its type:
public T getN(int index);
public void setN(int index, T value);
public T[ ] getN( );
public void setN(T values[ ]);
Here is an indexed property called data along with its getter and setter methods:
private double data[ ];
public double getData(int index) {
return data[index];
}
public void setData(int index, double value) {
data[index] = value;
}
public double[ ] getData( ) {
return data;
}
public void setData(double[ ] values) {
data = new double[values.length];
System.arraycopy(values, 0, data, 0, values.length);
}
Design Patterns for Events
Beans use the delegation event model that was discussed earlier in this topic. Beans
can generate events and send them to other objects. These can be identified by the
following design patterns, where T is the type of the event:
public void addTListener(TListener eventListener)
public void addTListener(TListener eventListener)
throws java.util.TooManyListenersException
public void removeTListener(TListener eventListener)
