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.
