Class ResourceConverter
The supportsType method defines what types a ResourceConverter supports. By default it returns true for classes that are equal to the constructor's type argument. The parseType methods converts a string the ResourceConverter's supported type, and the toString does the inverse, it converts a supported type to a String. Concrete ResourceConverter subclasses must override parseType() and, in most cases, the toString method as well.
This class maintains a registry of ResourceConverters. The forType method returns the first ResourceConverter that supports a particular type, new ResourceConverters can be added with register(). A small set of generic ResourceConverters are registered by default. They support the following types:
- Boolean
- Integer
- Float
- Double
- Long
- Short
- Byte
- MessageFormat
- URL
- URI
The Boolean ResourceConverter returns true for "true", "on", "yes", false otherwise. The other primitive type ResourceConverters rely on the corresponding static parseType method, e.g. Integer.parseInt(). The MessageFormat ResourceConverter just creates MessageFormat object with the string as its constructor argument. The URL/URI converters just apply the corresponding constructor to the resource string.
