Class DatevStreamWriter.Builder

java.lang.Object
io.github.mrtyldr.datev.plain.DatevStreamWriter.Builder
Enclosing class:
DatevStreamWriter
public static final class DatevStreamWriter.Builder extends Object
Configures a streaming writer, including the optional EXTF management record.

The static factories cover the common cases; this builder exists so schema, validator and metadata can be combined without a factory per combination. Nothing is written until one of the build methods is called. Instances are not thread-safe.
