Package de.iip_ecosphere.platform.connectors.parser

Class JsonInputParser

java.lang.Object

de.iip_ecosphere.platform.connectors.parser.JsonInputParser

All Implemented Interfaces:

InputParser<de.iip_ecosphere.platform.support.json.JsonIterator>

@MachineParser
public final class JsonInputParser
extends Object
implements InputParser<de.iip_ecosphere.platform.support.json.JsonIterator>

Implements the default input parser for JSON data. Name-based access shall be rather fast, however, index-based access is currently a limited compromise. Warning: This implementation is not stable and may change during performance optimization.
