Package com.thetransactioncompany.jsonrpc2.util Description

Utility classes for typed retrieval of JSON-RPC 2.0 request parameters on the server side.

The following parameter type conversion choices are available:

• JSON true/false to Java boolean
• JSON number to Java int, long, float or double
• JSON string to java.lang.String
• Predefined (enumerated) JSON string to a Java enum constant or java.lang.String
• JSON array to Java boolean[], int[], long[], float[], double[] or string[] array, or to mixed type java.util.List
• JSON object to java.util.Map

If a parameter cannot be retrieved, either because it's missing or is of the wrong type, a standard JSONRPC2Error.INVALID_PARAMS exception is thrown.

There are two concrete classes:

• The PositionalParamsRetriever class is for extracting positional parameters (packed in a JSON array).
• The NamedParamsRetriever class is for extracting named parameters (packed in a JSON object).

Package dependencies: The classes in this package depend on the sister com.thetransactioncompany.jsonrpc2 package.
