Rule

java.lang.Object
- org.osgi.util.converter.Rule<F,T>

T - The type to convert to.

All Implemented Interfaces:

TargetRule
```
public abstract class Rule<F,T>
extends java.lang.Object
implements TargetRule

A rule implementation that works by capturing the type arguments via subclassing. The rule supports specifying both from and to types. Filtering on the from by the Rule implementation. Filtering on the to is done by the converter customization mechanism.
