Class Emitter

  • All Implemented Interfaces:
    Emitable
    public final class Emitter
extends java.lang.Object
implements Emitable
     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
