Description copied from interface: Converter

Converts the given object into an object of the target type. Conversions can be implemented in any way that makes sense. Normally, converters will return null for null, but some converters may choose to interpret null as an indicator to return a default-initialized target object. An example of this type of conversion is the ShellExecutor. null simply indicates that no preference overrides of any kind have been provided.

Specified by:

fromObject in interface Converter<java.lang.String>

Parameters:

obj - the source object.

ctx - the context in which the conversion takes place.

Returns:

an instance of the target type or null.
