class Psych::Coder
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.

(tag = @tag, style = @style) { |self| ... }
Emit a map. The coder will be yielded to the block.

(map)
Emit a map with value

(tag, map)
Emit a sequence with map
and tag
# File ext/psych/lib/psych/coder.rb, line 54 def represent_map tag, map @tag = tag self.map = map end
represent_object
(tag, obj)
Emit an arbitrary object obj
and tag

Emit a scalar with value
and tag

(tag, list)
Emit a sequence with list
