## Class JsonStreamFactory

- java.lang.Object
- - org.apache.synapse.commons.staxon.core.json.stream.JsonStreamFactory

- Direct Known Subclasses:
    JsonStreamFactoryImpl

      public abstract class JsonStreamFactory
      extends Object

  Abstract JSON stream (`JsonStreamSource` and `JsonStreamTarget`) factory.

  This class provides the static `newFactory()` method to lookup and instantiate a default implementation using the Services API (as detailed in the JAR specification).

    - #### newFactory

          public static JsonStreamFactory newFactory()
                                              throws FactoryConfigurationError

      Create a new instance of a JsonStreamFactory.

      Determines the class to instantiate as follows:

      1. Use the Services API (as detailed in the JAR specification). If a resource with the name of META-INF/services/de.odysseus.staxon.json.stream.JsonStreamFactory exists, then its first line, if present, is used as the UTF-8 encoded name of the implementation class.
      2. Use the properties file "lib/staxon.properties" in the JRE directory. If this file exists and is readable by the java.util.Properties.load(InputStream) method, and it contains an entry whose key is "de.odysseus.staxon.json.stream.JsonStreamFactory", then the value of that entry is used as the name of the implementation class.
      3. Use the de.odysseus.staxon.json.stream.JsonStreamFactory system property. If a system property with this name is defined, then its value is used as the name of the implementation class.
      4. Use platform default: "de.odysseus.staxon.json.stream.impl.JsonStreamFactoryImpl".
      Returns:
        An instance of JsonStreamFactory.
      Throws:
        `FactoryConfigurationError` - if a factory class cannot be found or instantiation fails.
