public class PropertyEditorManager extends 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 primitive types "boolean", "byte", "short", "int", "long", "float", and "double"; and for the classes java.lang.String. java.awt.Color, and java.awt.Font.

null,
then any existing definition will be removed.
Thus this method can be used to cancel the registration.
The registration is canceled automatically
if either the target or editor class is unloaded.
If there is a security manager, its checkPropertiesAccess
method is called. This could result in a SecurityException.
