convert

public java.lang.Object convert(java.util.Properties properties,
                                java.lang.String type)

Description copied from interface: Converter

Turn a String-based tree-structure into an Object. Additionally the type of object desired is known. This is usually a Java class, but this is not mandatory.

The properties structure is located at the point of the lookup key, so if the code asked for a com.example.Foo object, the properties structure would be everything below Foo.

To get at the value of com.example.Foo itself, request the empty string, "".

TODO: No way for a converter to know the delimiter-type.

Specified by:

convert in interface Converter

Parameters:

properties - a Properties data structure

type - a String representation of object desired
