public Reflection(java.lang.Object instance,
                  java.lang.Class<T> valueType,
                  java.lang.reflect.Method getter,
                  java.lang.reflect.Method setter)
```
    Create a support with method objects specified. The methods must be public.
    
    Parameters:
    
    instance - (Bean) object to work on
    
    valueType - type of the property
    
    getter - getter method, can be null
    
    setter - setter method, can be null
    
    Throws:
    
    java.lang.IllegalArgumentException - if the methods are not public
  - Reflection
```
public Reflection(java.lang.Object instance,
                  java.lang.Class<T> valueType,
                  java.lang.String getter,
                  java.lang.String setter)
           throws java.lang.NoSuchMethodException
```
    Create a support with methods specified by name. The instance class will be examined for the named methods. But if the instance class is not public, the nearest public superclass will be used instead, so that the getters and setters remain accessible.
    
    Parameters:
    
    instance - (Bean) object to work on
    
    valueType - type of the property
    
    getter - name of getter method, can be null
    
    setter - name of setter method, can be null
    
    Throws:
    
    java.lang.NoSuchMethodException - if the getter or setter methods cannot be found
  - Reflection
```
public Reflection(java.lang.Object instance,
                  java.lang.Class<T> valueType,
                  java.lang.String property)
           throws java.lang.NoSuchMethodException
```
    Create a support based on the property name. The getter and setter methods are constructed by capitalizing the first letter in the name of propety and prefixing it with get and set, respectively.
    
    Parameters:
    
    instance - object to work on
    
    valueType - type of the property
    
    property - name of property
    
    Throws:
    
    java.lang.NoSuchMethodException - if the getter or setter methods cannot be found
- Method Detail
  - canRead
```
public boolean canRead()
```
    Description copied from class: Node.Property
    
    Test whether the property is readable.
    
    Specified by:
    
    canRead in class Node.Property<T>
    
    Returns:
    
    true if it is
  - getValue
```
public T getValue()
           throws java.lang.IllegalAccessException,
                  java.lang.IllegalArgumentException,
                  java.lang.reflect.InvocationTargetException
```
    Description copied from class: Node.Property
    
    Get the value.
    
    Specified by:
    
    getValue in class Node.Property<T>
    
    Returns:
    
    the value of the property
    
    Throws:
    
    java.lang.IllegalAccessException - cannot access the called method
    
    java.lang.reflect.InvocationTargetException - an exception during invocation
    
    java.lang.IllegalArgumentException
  - canWrite
```
public boolean canWrite()
```
    Description copied from class: Node.Property
    
    Test whether the property is writable.
    
    Specified by:
    
    canWrite in class Node.Property<T>
    
    Returns:
    
    true if the read of the value is supported
  - setValue
```
public void setValue(T val)
              throws java.lang.IllegalAccessException,
                     java.lang.IllegalArgumentException,
                     java.lang.reflect.InvocationTargetException
```
    Description copied from class: Node.Property
    
    Set the value.
    
    Specified by:
    
    setValue in class Node.Property<T>
    
    Parameters:
    
    val - the new value of the property
    
    Throws:
    
    java.lang.IllegalAccessException - cannot access the called method
    
    java.lang.IllegalArgumentException - wrong argument
    
    java.lang.reflect.InvocationTargetException - an exception during invocation
  - getPropertyEditor
```
public java.beans.PropertyEditor getPropertyEditor()
```
    Description copied from class: Node.Property
    
    Get a property editor for this property. The default implementation uses standard Java PropertyEditorManager. If a property editor is found, its instance is cached using SoftReference. Caching happens per thread - e.g. it is guaranteed that multiple threads accessing the editor will get different instance.
    
    Overrides:
    
    getPropertyEditor in class Node.Property<T>
    
    Returns:
    
    the property editor, or null if there is no editor
  - setPropertyEditorClass
```
public void setPropertyEditorClass(java.lang.Class<? extends java.beans.PropertyEditor> clazz)
```
    Set the property editor explicitly.
    
    Parameters:
    
    clazz - class type of the property editor
