Class org.codehaus.jackson.map.ObjectMapper

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

org.codehaus.jackson.map.ObjectMapper.readValue()
Method to deserialize Json content into a non-container type (it can be an array type, however): typically a bean, array or a wrapper type (like {@link java.lang.Boolean}).
Note: this method should NOT be used if the result type is a container ( {@link java.util.Collection} or {@link java.util.Map}. The reason is that due to type erasure, key and value types can not be introspected when using this method.
