Class java.beans.PropertyEditorManager

java.lang.Object
   |
   +----java.beans.PropertyEditorManager

public class PropertyEditorManager
extends Object
The PropertyEditorManager can be used to locate a property editor for any given type name. This property editor must support the java.beans.PropertyEditor interface for editing a given object.

The PropertyEditorManager uses three techniques for locating an editor for a given type. First, it provides a registerEditor method to allow an editor to be specifically registered for a given type. Second it tries to locate a suitable class by adding "Editor" to the full qualified classname of the given type (e.g. "foo.bah.FozEditor"). Finally it takes the simple classname (without the package name) adds "Editor" to it and looks in a search-path of packages for a matching class.

So for an input class foo.bah.Fred, the PropertyEditorManager would first look in its tables to see if an editor had been registered for foo.bah.Fred and if so use that. Then it will look for a foo.bah.FredEditor class. Then it will look for (say) standardEditorsPackage.FredEditor class.

Default PropertyEditors will be provided for the Java builtin types "boolean", "byte", "short", "int", "long", "float", and "double"; and for the classes java.lang.String. java.awt.Color, and java.awt.Font.
