Method Details
-
provider
Creates a JSON provider object. The provider is loaded using theServiceLoader.load(Class)
method. If there are no available service providers, this method returns the default service provider.- Returns:
- a JSON provider
- See Also:
-
createParser
Creates a JSON parser from a character stream.- Parameters:
reader
- i/o reader from which JSON is to be read- Returns:
- a JSON parser
-
createParser
Creates a JSON parser from the specified byte stream. The character encoding of the stream is determined as defined in RFC 4627 .- Parameters:
in
- i/o stream from which JSON is to be read- Returns:
- a JSON parser
- Throws:
JsonException
- if encoding cannot be determined or i/o error (IOException would be cause of JsonException)
-
createParserFactory
Creates a parser factory for creatingJsonParser
instances. The factory is configured with the specified map of provider specific configuration properties. Provider implementations should ignore any unsupported configuration properties specified in the map.- Parameters:
config
- a map of provider specific properties to configure the JSON parsers. The map may be empty or null- Returns:
- a JSON parser factory
-
createGenerator
Creates a JSON generator for writing JSON text to a character stream.- Parameters:
writer
- a i/o writer to which JSON is written- Returns:
- a JSON generator
-
createGenerator
Creates a JSON generator for writing JSON text to a byte stream.- Parameters:
out
- i/o stream to which JSON is written- Returns:
- a JSON generator
-
createGeneratorFactory
Creates a generator factory for creatingJsonGenerator
instances. The factory is configured with the specified map of provider specific configuration properties. Provider implementations should ignore any unsupported configuration properties specified in the map.- Parameters:
config
- a map of provider specific properties to configure the JSON generators. The map may be empty or null- Returns:
- a JSON generator factory
-
createReader
Creates a JSON reader from a character stream.- Parameters:
reader
- a reader from which JSON is to be read- Returns:
- a JSON reader
-
createReader
Creates a JSON reader from a byte stream. The character encoding of the stream is determined as described in RFC 4627.- Parameters:
in
- a byte stream from which JSON is to be read- Returns:
- a JSON reader
-
createWriter
- Parameters:
writer
- to which JSON object or array is written- Returns:
- a JSON writer
-
createWriter
Creates a JSON writer to write a JSONobject
orarray
structure to the specified byte stream. Characters written to the stream are encoded into bytes using UTF-8 encoding.- Parameters:
out
- to which JSON object or array is written- Returns:
- a JSON writer
-
createWriterFactory
Creates a writer factory for creatingJsonWriter
objects. The factory is configured with the specified map of provider specific configuration properties. Provider implementations should ignore any unsupported configuration properties specified in the map.- Parameters:
config
- a map of provider specific properties to configure the JSON writers. The map may be empty or null- Returns:
- a JSON writer factory
-
createReaderFactory
Creates a reader factory for creatingJsonReader
objects. The factory is configured with the specified map of provider specific configuration properties. Provider implementations should ignore any unsupported configuration properties specified in the map.- Parameters:
config
- a map of provider specific properties to configure the JSON readers. The map may be empty or null- Returns:
- a JSON reader factory
-
createObjectBuilder
Creates a JSON object builder- Returns:
- a JSON object builder
-
createArrayBuilder
Creates a JSON array builder- Returns:
- a JSON array builder
-
createBuilderFactory
Creates a builder factory for creatingJsonArrayBuilder
andJsonObjectBuilder
objects. The factory is configured with the specified map of provider specific configuration properties. Provider implementations should ignore any unsupported configuration properties specified in the map.- Parameters:
config
- a map of provider specific properties to configure the JSON builders. The map may be empty or null- Returns:
- a JSON builder factory
