Interface JsonReaderFactory

public interface JsonReaderFactory

Factory to create JsonReader instances. If a factory instance is configured with some configuration, that would be used to configure the created reader instances.

JsonReader can also be created using Json's createReader methods. If multiple reader instances are created, then creating them using a reader factory is preferred.

For example:

 
 JsonReaderFactory factory = Json.createReaderFactory(...);
 JsonReader reader1 = factory.createReader(...);
 JsonReader reader2 = factory.createReader(...);
 
 

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

Method Detail

createReader

JsonReader createReader(Reader reader)

Creates a JSON reader from a character stream. The reader is configured with the factory configuration.

Parameters:

reader - a reader from which JSON is to be read

JsonReader createReader(InputStream in,
                        Charset charset)

Creates a JSON reader from a byte stream. The bytes of the stream are decoded to characters using the specified charset. The reader is configured with the factory configuration.

Parameters:

in - a byte stream from which JSON is to be read

charset - a charset

Returns:

a JSON reader

getConfigInUse

Map<String,?> getConfigInUse()

Returns read-only map of supported provider specific configuration properties that are used to configure the created JSON readers. 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 readers. The map be empty but not null.
