Examples of com.fasterxml.jackson.core.SerializableString

com.fasterxml.jackson.core.SerializableString
Interface that defines how Jackson package can interact with efficient pre-serialized or lazily-serialized and reused String representations. Typically implementations store possible serialized version(s) so that serialization of String can be done more efficiently, especially when used multiple times. @see com.fasterxml.jackson.core.io.SerializedString
