Method Details

parseString

public static JsonElement parseString(String json)
                               throws JsonSyntaxException

Parses the specified JSON string into a parse tree. An exception is thrown if the JSON string has multiple top-level JSON elements, or if there is trailing data.

The JSON string is parsed in lenient mode.

Parameters:

json - JSON text

Returns:

a parse tree of JsonElements corresponding to the specified JSON

Throws:

JsonParseException - if the specified text is not valid JSON

JsonSyntaxException

Since:

2.8.6

parseReader

public static JsonElement parseReader(Reader reader)
                               throws JsonIOException,
JsonSyntaxException

Parses the complete JSON string provided by the reader into a parse tree. An exception is thrown if the JSON string has multiple top-level JSON elements, or if there is trailing data.

The JSON data is parsed in lenient mode.

Parameters:

reader - JSON text

Returns:

a parse tree of JsonElements corresponding to the specified JSON

Throws:

JsonParseException - if there is an IOException or if the specified text is not valid JSON

JsonIOException

JsonSyntaxException

parseReader

public static JsonElement parseReader(JsonReader reader)
                               throws JsonIOException,
JsonSyntaxException

Returns the next value from the JSON stream as a parse tree. Unlike the other parse methods, no exception is thrown if the JSON data has multiple top-level JSON elements, or if there is trailing data.

The JSON data is parsed in lenient mode, regardless of the lenient mode setting of the provided reader. The lenient mode setting of the reader is restored once this method returns.

Throws:

JsonParseException - if there is an IOException or if the specified text is not valid JSON

JsonIOException
