Example 1 with Indenter

use of com.fasterxml.jackson.core.util.DefaultPrettyPrinter.Indenter in project rdf4j by eclipse.

        Indenter indenter = DefaultIndenter.SYSTEM_LINEFEED_INSTANCE;
        // By default Jackson does not pretty print, so enable this unless
        // PRETTY_PRINT setting is disabled
        DefaultPrettyPrinter pp = new DefaultPrettyPrinter().withArrayIndenter(indenter).withObjectIndenter(indenter);

                // contexts are optional, so this may return empty in some
                // scenarios depending on the interpretation of the way contexts
                // work
