Examples of de.ddb.conversion.Converter

de.ddb.conversion.Converter

Basic interface for all converters.

A CharstreamConverter operates on Character streams. You can use it to define Conversions between record or document formats.
It is possible to pipe multiple Converters using the setPreConverter and setPostConverter methods.

Any {@link Converter} has to provide a {@link ConverterContext} object. Thisis used to access converter specific details or properties.
