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.

JsonParser	createParser(JsonArray array) Creates a JSON parser from the specified JSON array.
JsonParser	createParser(JsonObject obj) Creates a JSON parser from the specified JSON object.
JsonParser	createParser(Reader reader) Creates a JSON parser from a character stream.
Map<String,?>	getConfigInUse() Returns a read-only map of supported provider specific configuration properties that are used to configure the JSON parsers.

Method Detail

createParser

JsonParser createParser(Reader reader)

Creates a JSON parser from a character stream.

Parameters:

reader - a i/o reader from which JSON is to be read

Returns:

the created JSON parser

createParser

JsonParser createParser(InputStream in)

Creates a JSON parser from the specified byte stream. The character encoding of the stream is determined as specified in RFC 7159.

Parameters:

in - i/o stream from which JSON is to be read

Returns:

the created JSON parser

Throws:

JsonException - if encoding cannot be determined or i/o error (IOException would be cause of JsonException)

createParser

JsonParser createParser(InputStream in,
                        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

Map<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
