## Class CBORFactory

- java.lang.Object
- - com.fasterxml.jackson.core.JsonFactory
  - - com.fasterxml.jackson.dataformat.cbor.CBORFactory

- All Implemented Interfaces:
    com.fasterxml.jackson.core.Versioned, Serializable

      public class CBORFactory
      extends com.fasterxml.jackson.core.JsonFactory

  Factory used for constructing `CBORParser` and `CBORGenerator` instances; both of which handle CBOR encoded data.

  Extends `JsonFactory` mostly so that users can actually use it in place of regular non-CBOR factory instances.

  Note on using non-byte-based sources/targets (char based, like `Reader` and `Writer`): these can not be used for CBOR documents; attempt will throw exception.

  - ### Constructor Detail

    - #### CBORFactory

          public CBORFactory()

      Default constructor used to create factory instances. Creation of a factory instance is a light-weight operation, but it is still a good idea to reuse limited number of factory instances (and quite often just a single instance): factories are used as context for storing some reused processing objects (such as symbol tables parsers use) and this reuse only works within context of a single factory instance.
