YAML::PP::Constructor

Constructing data structure from parsing events

METHODS

• new

  The Constructor constructor

  my $constructor = YAML::PP::Constructor->new(
      schema => $schema,
      cyclic_refs => $cyclic_refs,
  );
  

• init

  Resets any data being used during construction.

  $constructor->init;
  

• document_start_event, document_end_event, mapping_start_event, mapping_end_event, sequence_start_event, sequence_end_event, scalar_event, alias_event, stream_start_event, stream_end_event

  These methods are called from YAML::PP::Parser:

  $constructor->document_start_event($event);
  

• anchors, set_anchors

  Helper for storing anchors during construction

• docs, set_docs

  Helper for storing resulting documents during construction

• stack, set_stack

  Helper for storing data during construction

• cyclic_refs, set_cyclic_refs

  Option for controlling the behaviour when finding circular references

• schema, set_schema

  Holds a YAML::PP::Schema object

• stringify_complex

  When constructing a hash and getting a non-scalar key, this method is used to stringify the key.

  It uses a terse Data::Dumper output. Other modules, like YAML::XS, use the default stringification, ARRAY(0x55617c0c7398) for example.
