Class ReaderUser<ResultType,DataType>

java.lang.Object

rife.tools.ReaderUser<ResultType,DataType>

All Implemented Interfaces:

Cloneable

public abstract class ReaderUser<ResultType,DataType>
extends Object
implements Cloneable

By extending this class it's possible to provide the logic that should be executed by methods that allow interaction with a Reader.

This class has both a default constructor and one that can take a data object. This can be handy when using it as an extending anonymous inner class when you need to use variables inside the inner class that are cumbersome to change to final in the enclosing class.

Since:

1.0
