Class TypedProperties

java.lang.Object
org.moeaframework.util.TypedProperties
All Implemented Interfaces:
Displayable
public class TypedProperties extends Object implements Displayable
Stores a collection of key-value pairs similar to Properties but has support for reading and writing primitive types. Internally, this handles converting specific types to a string representation that can be saved and read from files. In addition to primitive types, arrays of those primitives are also supported using either the default "," separator or a user-configurable string. Leading and trailing whitespace is automatically trimmed from each entry. Be mindful that values saved in arrays should not include the separator character(s) - no escaping is performed! From version 3.0+, keys are case-insensitive.
