Module: MultiJson Deprecated

Defined in:
lib/multi_json/legacy_constant.rb

Overview

Deprecated.

Use MultiJSON (all-caps) instead. Will be removed in v2.0.

Backward-compatible alias for the legacy MultiJson constant name

Downstream code that still writes MultiJson.parse(...) or rescue MultiJson::ParseError continues to work, but emits a one-time deprecation warning pointing at MultiJSON. Each public method on MultiJSON gets an explicit forwarder defined on this module, and constant access resolves via MultiJson.const_missing, so both dotted calls and :: constant lookups (including rescue clauses) route through the canonical module.

This file is loaded last by the multi_json entry point so the forwarder snapshot below sees the complete MultiJSON public API, including the deprecated aliases defined in deprecated.rb.

.const_missing(name) ⇒ Object

  • name (Symbol) —

    constant name

Returns:

  • (Object) —

    the resolved constant from MultiJSON
