Class GProperties

java.lang.Object
ghidra.framework.options.GProperties
Direct Known Subclasses:
JSonProperties, XmlProperties
public class GProperties extends Object
Class for saving name/value pairs as XML or Json. Classes that want to be able to save their state can do so using the GProperies object. The idea is that each state variable in the class is first saved into a GProperties object via a String key. Then the GProperties object is written out as XML or Json. When the GProperties object is restored, the GProperties object is constructed with an XML Element or JsonObject that contains all of the name/value pairs. There are convenience subclasses for reading these from a file (XmlProperties and JsonProperties). Since the "get" methods require a default value, the object that is recovering its state variables will be successfully initialized even if the given key,value pair is not found in the SaveState object.

Note: Names for property names are assumed to be unique. When a putXXX() method is called, if a value already exists for a name, it will be overwritten.

The GProperties supports the following types: 

      java primitives
      arrays of java primitives
      String
      Color
      Font
      KeyStroke
      File
      Date
      Enum
      GProperties (values can be nested GProperties)
