Class EmbulkYamlTagResolver

java.lang.Object

org.yaml.snakeyaml.resolver.Resolver

org.embulk.util.snakeyaml.EmbulkYamlTagResolver

public final class EmbulkYamlTagResolver
extends Resolver

Embulk's customized SnakeYaml Resolver which converts a node (scalar, sequence, map, or !!tag with them) to a tag (INT, FLOAT, STR, SEQ, MAP, ...).

For example, it converts "123" (scalar) to 123 (INT), or "true" (scalar) to true (BOOL). This is called by SnakeYaml's Composer which converts parser events into an object.

Note that jackson-dataformat-yaml doesn't use this because it traverses parser events without using Composer.
