Package javax.json.stream

Interface JsonParserFactory


  • public interface JsonParserFactory
    Factory for creating JsonParser instances. If a factory instance is configured with a configuration, the configuration applies to all parser instances created using that factory instance.

    The class Json also provides methods to create JsonParser instances, but using JsonParserFactory is preferred when creating multiple parser instances as shown in the following example: 

     
 JsonParserFactory factory = Json.createParserFactory();
 JsonParser parser1 = factory.createParser(...);
 JsonParser parser2 = factory.createParser(...);

    All the methods in this class are safe for use by multiple concurrent threads.

        the created JSON parser

      • createParser

        JsonParser createParser​(java.io.InputStream in)
        Creates a JSON parser from the specified byte stream. The character encoding of the stream is determined as specified in RFC 7159.

      • createParser

        JsonParser createParser​(java.io.InputStream in,
                        java.nio.charset.Charset charset)
        Creates a JSON parser from the specified byte stream. The bytes of the stream are decoded to characters using the specified charset.
        Parameters:
        in - i/o stream from which JSON is to be read
        charset - a charset
        Returns:
        the created JSON parser

      • createParser

        JsonParser createParser​(JsonObject obj)
        Creates a JSON parser from the specified JSON object.
        Parameters:
        obj - a JSON object
        Returns:
        the created JSON parser

      • createParser

        JsonParser createParser​(JsonArray array)
        Creates a JSON parser from the specified JSON array.
        Parameters:
        array - a JSON array
        Returns:
        the created JSON parser

      • getConfigInUse

        java.util.Map<java.lang.String,?> getConfigInUse​()
        Returns a read-only map of supported provider specific configuration properties that are used to configure the JSON parsers. If there are any specified configuration properties that are not supported by the provider, they won't be part of the returned map.
        Returns:
        a map of supported provider specific properties that are used to configure the created parsers. The map may be empty but not null
