Class org.codehaus.jackson.map.ObjectMapper

Examples of org.codehaus.jackson.map.ObjectMapper.writeValueAsString()

org.codehaus.jackson.map.ObjectMapper.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. @since 1.3


    ArrayList<String> serializable = new ArrayList<String>();
    serializable.add("foo");


    ObjectMapper mapper = new ObjectMapper();
    String jsonBytes = mapper.writeValueAsString(serializable);
    String typeName = TypeFactory.type(serializable.getClass()).toCanonical();


    String variableKey = "aVariableKey";
