Interface ConfigSource

All Superinterfaces:

DataSource

public interface ConfigSource
extends DataSource

Represents an Embulk configuration for a plugin.

It had two following methods that return Jackson's instances till v0.9, but they are removed so that Jackson on the core side can be hidden from plugins.

• Iterable<Map.Entry<String, JsonNode>> getAttributes()
• ObjectNode getObjectNode()
