Examples of org.yaml.snakeyaml.emitter.Emitter$ExpectFirstFlowMappingKey

org.yaml.snakeyaml.emitter.Emitter

 Emitter expects events obeying the following grammar: stream ::= STREAM-START document* STREAM-END document ::= DOCUMENT-START node DOCUMENT-END node ::= SCALAR | sequence | mapping sequence ::= SEQUENCE-START node* SEQUENCE-END mapping ::= MAPPING-START (node node)* MAPPING-END
