  info.javelot.functionalj.reflect.helper.impl.ReflectFinderImpl

All Implemented Interfaces:

ReflectFinder

public class ReflectFinderImpl
extends Object
implements ReflectFinder

Implementation of a way to find Methods and Constructors.

Finding methods by name

This implementation searches methods by name in the following manner, in order of priority. For example, searching for "name" will look for:

• Exact match: "name"
• Corresponding getter: "getName"
• Corresponding setter: "setName"
• Corresponding boolean flag: "isName"
