If an object defines encode_with
, then an instance of Psych::Coder
will be passed to the method when the object is being serialized. The Coder
automatically assumes a Psych::Nodes::Mapping
is being emitted. Other objects like Sequence and Scalar may be emitted if seq=
or scalar=
are called, respectively.

# File psych/lib/psych/coder.rb, line 78 def []= k, v @type = :map @map[k] = v end
Emit a map. The coder will be yielded to the block.
# File psych/lib/psych/coder.rb, line 34 def map tag = @tag, style = @style @tag = tag @style = style yield self if block_given? @map end
Emit a map with value
# File psych/lib/psych/coder.rb, line 73 def map= map @type = :map @map = map end
Emit a sequence with map
and tag
# File psych/lib/psych/coder.rb, line 54 def represent_map tag, map @tag = tag self.map = map end
Emit an arbitrary object obj
and tag
# File psych/lib/psych/coder.rb, line 60 def represent_object tag, obj @tag = tag @type = :object @object = obj end
Emit a scalar with value
and tag
# File psych/lib/psych/coder.rb, line 42 def represent_scalar tag, value self.tag = tag self.scalar = value end
Emit a sequence with list
and tag
# File psych/lib/psych/coder.rb, line 48 def represent_seq tag, list @tag = tag self.seq = list end
# File psych/lib/psych/coder.rb, line 24 def scalar *args if args.length > 0 warn "#{caller[0]}: Coder#scalar(a,b,c) is deprecated" if $VERBOSE @tag, @scalar, _ = args @type = :scalar end @scalar end
