configure

public void configure(int t)

Description copied from interface: ConfigurableTransformer

If a transformer can handle more then one destination format, it can be configured with this. There must be a default, since to can be null.

Specified by:

configure in interface ConfigurableTransformer

Used when registering this class as a possible Transformer

Specified by:

transformers in interface ConfigurableTransformer

Returns:

A Map with String Integer/Class pairs.
