类 JsonStringEncoder

java.lang.Object

org.codehaus.jackson.io.JsonStringEncoder

public final class JsonStringEncoder
extends Object

Helper class used for efficient encoding of JSON String values (including JSON field names) into Strings or UTF-8 byte arrays.

Note that methods in here are somewhat optimized, but not ridiculously so. Reason is that conversion method results are expected to be cached so that these methods will not be hot spots during normal operation.
