Method Detail

evaluate

Object evaluate(JSRealm realm,
                com.oracle.truffle.api.nodes.Node lastNode,
                com.oracle.truffle.api.source.Source code)

Evaluate using the global execution context. For example, this method can be used to compute the result of indirect calls to eval.

Parameters:

lastNode - the node invoking the eval or null

evaluate

Object evaluate(JSRealm realm,
                com.oracle.truffle.api.nodes.Node lastNode,
                com.oracle.truffle.api.source.Source source,
                com.oracle.truffle.api.frame.MaterializedFrame frame,
                Object thisObj,
                Object currEnv)

Evaluate using the local execution context. For example, this method can be used to compute the result of direct calls to eval.

Parameters:

lastNode - the node invoking the eval or null

parseDate

Integer[] parseDate(JSRealm realm,
                    String date)

parseToJSON

String parseToJSON(JSContext context,
                   String code,
                   String name,
