Examples of com.fasterxml.jackson.core.JsonFactory

com.fasterxml.jackson.core.JsonFactory
The main factory class of Jackson package, used to configure and construct reader (aka parser, {@link JsonParser}) and writer (aka generator, {@link JsonGenerator}) instances.
Factory instances are thread-safe and reusable after configuration (if any). Typically applications and services use only a single globally shared factory instance, unless they need differently configured factories. Factory reuse is important if efficiency matters; most recycling of expensive construct is done on per-factory basis.
Creation of a factory instance is a light-weight operation, and since there is no need for pluggable alternative implementations (as there is no "standard" JSON processor API to implement), the default constructor is used for constructing factory instances. @author Tatu Saloranta
