Class ReflectionMap<V>

java.lang.Object

org.apache.juneau.utils.ReflectionMap<V>

Type Parameters:

V - The type of object in this map.

public class ReflectionMap<V>
extends Object

Allows arbitrary objects to be mapped to classes and methods base on class/method name keys.

The valid pattern matches are:

• Classes:
  • Fully qualified:
    • "com.foo.MyClass"
  • Fully qualified inner class:
    • "com.foo.MyClass$Inner1$Inner2"
  • Simple:
    • "MyClass"
  • Simple inner:
    • "MyClass$Inner1$Inner2"
    • "Inner1$Inner2"
    • "Inner2"
• Methods:
  • Fully qualified with args:
    • "com.foo.MyClass.myMethod(String,int)"
    • "com.foo.MyClass.myMethod(java.lang.String,int)"
    • "com.foo.MyClass.myMethod()"
  • Fully qualified:
    • "com.foo.MyClass.myMethod"
  • Simple with args:
    • "MyClass.myMethod(String,int)"
    • "MyClass.myMethod(java.lang.String,int)"
    • "MyClass.myMethod()"
  • Simple:
    • "MyClass.myMethod"
  • Simple inner class:
    • "MyClass$Inner1$Inner2.myMethod"
    • "Inner1$Inner2.myMethod"
    • "Inner2.myMethod"
• Fields:
  • Fully qualified:
    • "com.foo.MyClass.myField"
  • Simple:
    • "MyClass.myField"
  • Simple inner class:
    • "MyClass$Inner1$Inner2.myField"
    • "Inner1$Inner2.myField"
    • "Inner2.myField"
• Constructors:
  • Fully qualified with args:
    • "com.foo.MyClass(String,int)"
    • "com.foo.MyClass(java.lang.String,int)"
    • "com.foo.MyClass()"
  • Simple with args:
    • "MyClass(String,int)"
    • "MyClass(java.lang.String,int)"
    • "MyClass()"
  • Simple inner class:
    • "MyClass$Inner1$Inner2()"
    • "Inner1$Inner2()"
    • "Inner2()"
• A comma-delimited list of anything on this list.
