Class com.fasterxml.jackson.databind.ObjectMapper

Examples of com.fasterxml.jackson.databind.ObjectMapper.writeValueAsBytes()

com.fasterxml.jackson.databind.ObjectMapper.writeValueAsBytes()
Method that can be used to serialize any Java value as a byte array. Functionally equivalent to calling {@link #writeValue(Writer,Object)} with {@link java.io.ByteArrayOutputStream}and getting bytes, but more efficient. Encoding used will be UTF-8.
