This package contains classes to dynamically box and unbox KNIME types from and to Java types. A extension point is provided to allow implementors of custom KNIME data types to provide compatibility with nodes like the Java Snippet node, which use the KNIME Converter Framework.
org.knime.core.data.convert.datacell- For converting from DataCell to Java types.
org.knime.core.data.convert.java- For converting from Java types to DataCell.
Each of the aforementioned packages contain a
*ConverterRegistry class. All of the converters of the
respective types are registered and can be retrieved here.
For both of the converter types (
DataCellToJava) there are
*ConverterFactory classes which produce instances of
*Converter classes respectively. This
is required since the converter instances may require information only available during node execution and therefore
cannot be instantiated before this point.
If there is a Converter from e.g.
Integer, the framework can automatically
handle conversions form
Integer vice versa. Additionally there may
be explicit converters from a collection cell or array to a specific Java or DataCell type.
