Class com.fasterxml.jackson.databind.ObjectWriter

Examples of com.fasterxml.jackson.databind.ObjectWriter.writeValueAsString()

com.fasterxml.jackson.databind.ObjectWriter.writeValueAsString()
Method that can be used to serialize any Java value as a String. Functionally equivalent to calling {@link #writeValue(Writer,Object)} with {@link java.io.StringWriter}and constructing String, but more efficient.
Note: prior to version 2.1, throws clause included {@link IOException}; 2.1 removed it.

        final FilterProvider filters = new SimpleFilterProvider().addFilter("storedDataFilter", SimpleBeanPropertyFilter.serializeAllExcept("storedData"));


        final ObjectWriter ssWriter = mapper.writer(filters);
        final ObjectReader ssReader = mapper.reader(sus.getClass());
        
        final String susString = ssWriter.writeValueAsString(sus);
        System.out.println(susString);
        final StorelessUnivariateStatistic newSus = ssReader.readValue(susString);
        
        assertEquals(expected, newSus.getResult(), 0.1);
